Zach mows lawns. He charges $5 plus $3 per hour. Alex also mows lawns He charges $2 plus $4 per hour. How many hours do they need to work to make the same amount
Answer:
They both need to work 3 hours to get the same amount of $14.
Step-by-step explanation:
If you have a graphing calculator handy, just graph the two expressions 3x + 5 and 4x + 2 and look for the point where they intersect. If you don't have a graphing calculator set up the equation 3x + 5 = 4x + 2. Subtract 4x from both sides to get -x + 5 = 2. Then subtract 5 from both sides to get -x = -3. Since x shouldn't be negative, divide both sides by -1. You do this because just like x is 1x, -x is -1x. After dividing, you should get x = 3.
bob is on his way home in his car. he has driven 30 miles so far, which is three-fifths of the way home. what is the total length of his drive?
The length of Bob's drive as a fraction = 5/5
Let the length of his total drive be = x
30 miles driven by Bob as a fraction =
= 3/5 of x = 30
= 3/5x = 30
= 5/x = 30 ÷ 3 ( transposing ×3 from LHS to RHS changes ×3 to ÷3 )
=5/x = 10
= x = 10 × 5 ( transposing ÷5 from LHS to RHS changes ÷5 to ×5 )
= x = 50
Now we have to see what is =
= 2/5 of 50
= 2/5 × 50
= 100/5
= 20 miles
So , total length of Bob's drive = 30 miles + 20 miles = 50 miles .
∴ The total length of Bob's drive is 50 miles .

Simplify the algebraic expression by combining like (or similar) terms.
5+9x+2
Answer:
7 + 9x
Step-by-step explanation:
add 5 and 2 and 9x doesn't have a like term so it stays the same
Answer:
9x + 7
Step-by-step explanation:
Like terms are terms that have the same variables and powers. Here, for 9x, there is no other term that is multiplied by x. So, the only terms we can combine is 2 and 5 which leaves us with 9x+7.

Answer:
7
Step-by-step explanation:
7x7=49+5=54
Answer:
y = 7
Step-by-step explanation:
Alrighty, here we go!
First step is to subtract 5 from 5 and from 54. Cancel out the 5's.
After doing so, you have 7y = 49.
Now, divide 7 from 7y and from 49. Cancel out the 7's.
Now you have y = 7
There is your answer!

Melody is factoring the expression x^3 - 2x^2 + 4x - 8. Her first two steps are shown.
x^3 - 2x^2 + 4x - 8 = x^2(x - 2) + 4(x - 2)
= (x^2 + 4)(x - 2)
What should Melody do next to finish factoring the expression?
A. Melody has completely factored the expression.
B. Melody should rewrite (x^2 + 4) as (x - 2)^2
C. Melody should rewrite (x^2 + 4) as (x - 2)(x + 2)
D. Melody should rewrite (x^2 + 4) as (x + 2)^2
Answer:
A, melody completed factoring
Step-by-step explanation:
Melody has completely factored the expression which is correct option(A).
What is expression?Expressions is the defined as mathematical statements that have a minimum of two terms containing variables or numbers.
Given the expression,
⇒ x³ - 2x² + 4x - 8
⇒ x²(x - 2) + 4(x - 2)
⇒ (x² + 4)(x - 2)
So, factors of given expression are (x² + 4) and (x - 2).
Hence, Melody has completely factored the expression.

b. 2/3 ounce of icing per cupcake.
c. 1/2 ounce of icing per cupcake.
d. 3/4 ounce of icing per cupcake.
Answer:
b. 2/3 ounce of icing per cupcake.
Step-by-step explanation:
Given parameters:
Number of cupcakes = 24 cupcakes
Ounces of whipped icing = 16 ounces
Unknown:
How much icing was used in each cupcake = ?
Solution:
To find the number icing used per cupcake;
= [tex]\frac{number of ounces of whipped icing}{Number of cupckakes}[/tex]
Input the parameters;
= [tex]\frac{16 ounce of icing }{24 cupcake}[/tex]
= [tex]\frac{2}{3}[/tex] ounce of icing per cupcake

Answer please ? Find the perimeter of the figure ( must include all sides )
Answer:
32 ft
Step-by-step explanation:
First we can add up all the sides we already know as perimeter is the sum of all the lengths of a shape. 9+6+3+4 = 22
There are two unknown side lengths in the diagram, the long one at the top, and the short one between the 3ft side and the 4ft side. Luckily these can be easily found using the given sides. Since this shape is rectangular in nature (all 90-degree angles), the top length is the same as the bottom length. We know the total bottom length to be 7ft (3+4) so the top length must be 7ft as well.
Similarly, all the vertical lengths on the right side must be equal to the 9ft length on the left side, therefore the unknown length is 3ft (9-6).
Adding on these two new lengths and our total perimeter is 22+7+3 = 32ft.
Hope this helped!

The original price for a jacket is $124.95. It is on sale for 20% off. Which of the following gives the best estimate of the savings?
Answer:
24.99
Step-by-step explanation:
We first must figure out the current price of the jacket, we need to multiply the original price (124.95) times .80 (1.00 - .20). Doing so we get a total of 99.96. In order to find the savings, we subtract the original price by the new price. 124.95-99.96 = a savings of 24.99
Answer:
You would be saving 24.99 dollars
Step-by-step explanation:
Find 20% of 124.95 using P(percentage in decimal form) times X(original number) and you should have your answer.

On a coordinate plane, a function has a maximum of 0 and minimum of negative 4. It completes one period at 2 pi. It decreases through the y-axis at (0, negative 2).
Answer:
its b on edge 2021
Step-by-step explanation:
The required function h(x) is [tex]h (x) = 2 cos (x + \frac{11\pi }{8} ) - 3[/tex] . Option d is correct.
Function g(x) = [tex]2 cos (x +\frac{\pi }{2} )- 2[/tex]
Equation which includes trigonometric operators eg sin, cos.. etc.. In algebraic processes.
Here, the phase of the curve is increase by 7π/8.
So the phase = π/2 + 7π/8
= 11 π/8
And Shift of curve along y axis is by -1.
So, the total shift = -2-1
= -3
⇒ h(x) = [tex]2 cos (x + \frac{11\pi }{8} ) - 3[/tex]
Thus, h(x) = [tex]2 cos (x + \frac{11\pi }{8} ) - 3[/tex].

Use the personal tax per capita in a sentence explaining what this value means. 4 points
Answer:
Step-by-step explanation:
a. The personal tax collected for 2019 is $103.0 billion.
The tax in scientific notation = $1.03 x [tex]10^{11}[/tex]
b. The population in California is 39.50 million people.
The population in scientific notation = 3.95 x [tex]10^{7}[/tex]
c. Assuming that the whole population of people in Califonia are working i.e employed, the the Personal Tax Per Capita can be determined by;
Personal Tax Per Capita = [tex]\frac{income tax revenue}{taxable population}[/tex]
= [tex]\frac{103000000000}{39500000}[/tex]
= 2607.595
= 2.61 x [tex]10^{3}[/tex]
= 3.00 x [tex]10^{3}[/tex]
d. Therefore provided that the whole population of people in California for 2019 are employed, then each person pays an average of $2607.595 per annum in the year 2019.

Fifty students are going on a field trip. Twenty of the students are boys. What percent of the students are girls?
Answer:
60% would be the correct answer
Step-by-step explanation:
The girls percentage among students is 60%.
What is a percentage?A percentage is a proportion that shows a number as parts per hundred. If we have to calculate percent of a number, divide the number by the whole and multiply by 100.
For the given situation,
Total number of students = 50
Number of boys = 20
Number of girls = [tex]50-20[/tex]
⇒ [tex]30[/tex]
Thus, girls percentage is
⇒ [tex]\frac{30}{50}(100)[/tex]
⇒ [tex]60[/tex]
Hence we can conclude that the girls percentage among students is 60%.
