Answer:
t=6
Step-by-step explanation:
Solve for tt by simplifying both sides of the equation, then isolating the variable.
Answer:
t=6
Step-by-step explanation:
We first use the addition property of equality by adding 8 to both sides. This cancels out the "-8" on the left-hand side of the equation.
We get: 1/3t= 2.
Then, we multiply 3 to both sides of the equation to cancel out the fraction on the left-hand side of the equation.
We get: t=6
This is your final answer.

Explain the error in the work and how you might prevent it
Answer:
The error is -12x² - 14x = - 26x² because 12x² and 14x are unlike terms, so we can not add them
To prevent it the dividend must be written as 6x³ + 0x² - 14x + 1
Step-by-step explanation:
In the division, you must arrange the dividend according to the greatest power of the variable, and put 0 as a coefficient of the missing term to avoid adding, unlike terms.
Example:
If the dividend is 3x³ - 2x + 5, then you must write it as 3x³ + 0x² - 2x + 5
Let us solve our question
∵ The dividend is 6x³ + 1 - 14x
→ You must arrange it from the greatest power of x
∴ The dividend is 6x³ - 14x + 1
∵ The term of x² is missing
→ Write it in the dividend with a coefficient of 0
∴ The dividend is 6x³ + 0x² - 14x + 1
The error is the adding of unlike terms
∵ 6x³ - 14x + 1 ÷ 3x + 6 = 2x² and [6x³ - 14x + 1 - 6x³ - (6x³ + 12x²)]
∵ [6x³ - 14x + 1 - 6x³ - (6x³ + 12x²)] = 6x³ - 14x + 1 - 6x³ - 12x²
∵ 6x³ - 14x + 1 - 6x³ - 12x² = 0 - 12x² - 14x + 1
∵ 0 - 12x² - 14x + 1 = -26x² + 1 ⇒ error
∴ The error is -12x² - 14x = - 26x² because 12x² and 14x are unlike terms,
so we can not add them
→ To prevent it, write 0 as a coefficient of the missing term
∵ The missing term is the term of x²
∴ Add to the dividend the term 0x²
∴ The dividend must be written as 6x³ + 0x² - 14x + 1
Answer:
-14x and 12x² are not like terms, so they can’t be subtracted.
To prevent this error, be sure to line up like terms

An arctic woolly-bear caterpillar lives for 7 years and spends 90% of its life frozen. How many days of its life is the arctic woolly-bear frozen? Round to the nearest whole day.
Answer:
2,300 days are without activities
Step-by-step explanation:
We start by calculating the number of days in 7 years
Mathematically, that would be 7 * 2,555
From the question, 90% of days are without activities
The number of days without activities will be;
90/100 * 2,555 = 2,299.5 which is approximately 2,300 days

Dwayne bought 11 shirts for the members of a club. He paid $7 for 10 shirts and $10 for 1 shirt. He also paid a one-time fee of $60 and $4 to embroider the club name on each shirt. Which expression could be used to determine how much he paid altogether for the 11 shirts?
Answer:
T = (7 * 10) + 10 + 60 + (4 * 11)
Step-by-step explanation:
The expression that can be used to determine the total cost would be the following ...
T = (7 * 10) + 10 + 60 + (4 * 11)
This expression sums up the cost of each shirt, the one-time fee, and the embroidery costs. Since 10 of the shirts cost $7 each then you need to multiply the cost by the number of shirts that cost that amount. The same goes for embroidery. Since there are a total of 11 shirts and each one costs $4 to embroider then you do 4 * 11
You live in a small town where the population is currently 5000 people.
However, the population is increasing by 20% each year. What will the
population be in the year 2035 if it continues to grow at that rate? Round to
the nearest person. (Hint: It will be 2035 in 15 years.] *
Answer:
The population of each year is,
20/100 * 5000 = 1000
The population of 15 years is,
1000 * 15 = 15000
The total of 15 plus the 5000 years is,
15000 + 5000 = 20000

A race car travels 276 feet each second. How many yards does the race car travel in 5 seconds if it maintains that speed?
Answer:
460 yards
Step-by-step explanation:
3 feet are in a yard so 276 feet / 1 second * 1 yard / 3 feet=92 yards per second
92 * 5 = 460 yards
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
If the car travels at a speed of 276 feet per second, the number of yards the race car travels in 5 seconds is 460 yards.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
Example:
A man can travel 3 miles in 60 minutes.
The man can travel 1 mile in 20 minutes.
We have,
A car travels 276 feet each second.
This can be written as:
276 feet = 1 second
Multiply both sides by 5 we get,
5 x 276 feet = 5 x 1 second
1380 feet = 5 second ____(1)
1 yard = 3 feet
Multiply both sides by 460.
460 x 1 yard = 460 x 3 feet
460 yard = 1380 feet ____(1)
From (1) and (2) we get,
460 yard = 5 seconds
Thus,
If the car travels at a speed of 276 feet per second, the number of yards the race car travels in 5 seconds is 460 yards.

Tom sold magazines for 4 days last week. The table above gives the total number of magazines Tom had
sold for the week at the end of each of the 4 days. Which of the following best models the relationship
between the total number M of magazines Tom sold and the number x of days selling?
O M(x)=x+4
O M(x)= 1.5x +4
20 M(x)= 4x + 4
> M(x)= 6x+4
Answer:
C. [tex] M(x) = 4x + 4 [/tex]
Step-by-step explanation:
Find the rate of change/slope (m) using two pairs (1, 8) and (2, 12):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 8}{2 - 1} = \frac{4}{1} = 4 [/tex]
(Note: M(x) = y)
Find y-intercept (b) by substituting x = 1, M(x) = 8, and m = 4 in M(x) = mx + b.
Thus:
8 = (4)(1) + b
8 = 4 + b
Subtract 4 from each side
8 - 4 = b
4 = b
b = 4
substitute m = 4, and b = 4 in M(x) = mx + b, to get the equation that models the relationship.
The equation would be:
✅ [tex] M(x) = 4x + 4 [/tex]
In this hanger, the weight of the triangle is x and the weight of the square is y. 1. Write an equation using x and y to represent the hanger. x + y = x + y 2. If x is 6, what is y?
Answer:
a. Equation is 3x - 2y = 0
b. x = 6 and y = 9
Step-by-step explanation:
a.
Given that
The Weight of the square is y
And, the weight of the triangle is x
Now the equation according to the attached diagram is
x + 3y = 4x + y
4x - x + 3y - y = 0
3x - 2y = 0
b.
Now if x = 6
So, y would be
3x - 2y = 0
3x = 2y
3(6) = 2y
18 = 2y
y = 9
We simply applied the above equation so that the correct value could come

Larry says 5 × 900 is less than 5 × 9,000. Doni says 5 × 900 is greater than 5 × 9,000. Which statements about the two products are correct? Choose all that apply.
Answer:
Larry's statement is correct
Step-by-step explanation:
Larry says 5 × 900 is less than 5 × 9,000.
Doni says 5 × 900 is greater than 5 × 9,000.
5 × 900 = 4500
5 × 9000 = 45,000
45,000 is greater than 4500 because the place value of 45,000 is tens thousands and 4500 is Thousands.
Hence, Larry's statement is correct.(Larry says 5 × 900 is less than 5 × 9,000.)

What is the length of the hypotenuse of a right triangle if each of the two legs is 4 units? (5 points)
Square root of 8 units
4 units
Square root of 32 units
8 units
Answer:
sq rt of 32 units
Step-by-step explanation:
use the pythagorean theorem:
4^2 + 4^2 = c^2
16 + 16 = c^2
32 = c^2
sq rt of 32 = c
The length of the hypotenuse of a right triangle is 4√2.
What is Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
Given:
P= 4 units, B= 4 units
Now, using Pythagoras theorem
H² = P² + B²
H² = 4² + 4²
H²= 16+ 16
H² =32
H= √32
H= 4√2
Hence, the Hypotenuse is 4√2.

What is the image of the point (-7, -3) after a rotation of 90° counterclockwise
about the origin?
The new point after rotation of point (-7, -3) counterclockwise by 90 degrees will be ( 3, -7).
What are coordinates?
A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).
Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.
For example (5,3) here 5 will be for the x and 3 will be for the y.
Another example is (9,0) here 9 is for x and 0 is for y.
Given,
Point A = (-7, -3)
Let's say after rotation this point moves to a new coordinate (x, y) which is point B
Let's say the origin is O
Slope of line segment AO = (-3-0)/(-7-0) = 3/7
Slope of line segment BO = (y - 0)/(x - 0) = y/x
Now,
Since both lines are perpendicular to each other so
Slope AO × Slope BO = -1
3/7 × y/x = -1 ⇒ 3y = -7x
Now if we observe the result then it will be clear that if we put x = 3 than y = -7 will be the new coordinate.
Hence, The new point after rotation of point (-7, -3) counterclockwise by 90 degrees will be ( 3, -7).
