sum of which is 45, so
that if 2 is added to
the first number, 2 is
subtracted from the
second number, the third
number is multiplied by
2, while the fourth
number is divided by 2,
then the four numbers so
produced are all the
same.

Troy needs to complete 45 hours of training. During the fall, Troy completed 12 hours of training, and during the spring he completed twice as many hours as he had during the fall. Which equation can be used to find how many more hours of training (h) Troy needs to complete? Select one:
Answer:
[tex]36 + h = 45[/tex]
[tex]h = 9[/tex]
Step-by-step explanation:
Given
[tex]Total = 45[/tex]
[tex]Fall = 12[/tex]
[tex]Spring = 2 * Fall[/tex]
Required
Determine the equation to find the hours (h) left
The sum of the hours spent during the fall, spring and the hours left must be equal to the total hours.
In other word;
[tex]Fall + Spring + h = Total[/tex]
Substitute 2 * Fall for Spring
[tex]Fall + 2 * Fall + h =Total[/tex]
Substitute values for Fall and Total
[tex]12 + 2 * 12 + h = 45[/tex]
[tex]12 + 24 + h = 45[/tex]
[tex]36 + h = 45[/tex]
The above represents the equation,
Solving further for h
[tex]h = 45 - 36[/tex]
[tex]h = 9[/tex]
Hence, there are 9 hours left
x divided by 8= 1.5 divided by 2
What is x?
When x divided by 8= 1.5 divided by 2 then the value of x is 6.
To solve for x in the equation "x divided by 8 equals 1.5 divided by 2," we can cross-multiply.
The equation can be written as:
x/8 = 1.5/2
To eliminate the fractions, we can multiply both sides of the equation by 8:
8×(x/8) = 8 × (1.5/2)
On the left side, the 8 in the numerator and denominator cancels out, leaving us with just x:
x = 8 × (1.5/2)
Now, let's simplify the right side of the equation:
x = 8 × 0.75
Multiplying 8 by 0.75 gives us:
x = 6
Therefore, x is equal to 6 in the given equation.

Can you work this out: 14 x 14?
Answer:
14x14 is 196
Step-by-step explanation:
Use a calculator lol 14x14 is simple
The product of the 14 x 14 is 196.
Given that we need to calculate 14 x 14,
To calculate 14 multiplied by 14, you simply multiply the two numbers together.
Here's the step-by-step process:
Start by multiplying the ones digit of the first number (4) by the ones digit of the second number (also 4).
4 x 4 = 16
Write down the ones digit of the result (6) and carry over the tens digit (1).
Next, multiply the tens digit of the first number (1) by the ones digit of the second number (4).
1 x 4 = 4
Add the carried over tens digit (1) to the result.
4 + 1 = 5
Write down the tens digit of the result (5) and carry over any remaining digits (none in this case).
Finally, multiply the tens digit of the first number (1) by the tens digit of the second number (1).
1 x 1 = 1
Write down the tens digit of the result (1).
Putting it all together, we get:
14 x 14 = 196
Operation:
14
× 14
------
56 (4 × 14)
+140 (10 × 14)
------
196
Therefore, 14 multiplied by 14 equals 196.

7,2,-3,-8,-13,-18
find the 97 term
Answer:
- 473
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 2 - 7 = - 3 - 2 = - 8 - (- 3) = - 13 - (- 8) = - 18 - (- 13) = - 5
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = - 5, thus
[tex]a_{97}[/tex] = 7 + (96 × - 5) = 7 - 480 = - 473
A one-year membership to Metro Gym costs $460. There is a fee of $40 when you join, and the rest is paid monthly. Write an equation to represent what you will pay monthly for the yearlong membership. Write an equation that would help members find how much they pay per month.
Answer: See explanation
Step-by-step explanation:
Let the amount of money to be paid per month be represented by x. The information given in the question can then be formed into an equation as:
$40 + 12x = $460
From the equation, the amount that'll be paid monthly will be:
$40 + 12x = $460
12x = $460 - $40
12x = $420
x = $420/12
x = $35
The amount paid monthly is $35

–3.4(x – 2) = 9.8 – 4x
Answer:
X= 5
Explanation (Steps):
Step 1: Simplify both sides of the equation.
−3.4(x−2)=9.8−4x
(−3.4)(x)+(−3.4)(−2)=9.8+−4x(Distribute)
−3.4x+6.8=9.8+−4x
−3.4x+6.8=−4x+9.8
Step 2: Add 4x to both sides.
−3.4x+6.8+4x=−4x+9.8+4x
0.6x+6.8=9.8
Step 3: Subtract 6.8 from both sides.
0.6x+6.8−6.8=9.8−6.8
0.6x=3
Step 4: Divide both sides by 0.6.
0.6x0.6=3/0.6

It is not equivalent.
Step-by-step explanation:
You have to expand the brackets :
(x-4)(x+3)
= x(x) + x(3) - 4(x) - 4(3)
= x² + 3x - 4x - 12
= x² - x - 12
Therefore, x² - x - 12 / (x-4)(x+3) is not equivalent to x² - 4x - 12.

Hue is arranging chairs. She can form 6 rows of a given length with 3 chairs left over, or 8 rows of that
same length if she gets 15 more chairs. Complete the equation and solve it to find how many chairs are inthat row length. In your equation, use the variable x to represent the number of chairs in each row.
Answer:
8r + 15 = x
Step-by-step explanation:
So being that they can form 6 rows but have 3 left over we know that there are more than three chairs in each row. So for example:
6r + 3 = x
or (x = chairs, r = chairs in the row)
8r + 15 = x

Juan invested $3,100 in an account paying an interest rate of 3.6% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest dollar, would be in the account after 19 years?
Answer:
A=6143.54( to the nearest dollar A=6144)
Step-by-step explanation:
A=Pe^(r(t))
P=3100 r=0.036 t=19
A=3100e^0.036(19)
A=3100e^(0.684)
There will be $6070 money in the account of Juan after 19 years.
What is Compound Interest?It is the interest on a loan or deposit calculated based on both the initial principal and accumulated interest from previous periods. It is calculated as:
[tex]Amount=P(1+\frac{r}{n} )^{nt}[/tex]
where,
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of periods elapsed
We have
principal, P= $3100
Rate, r = 3.6%=[tex]\frac{3.6}{100}[/tex]
time, t = 19years
number of times interest compounded per year, n=1
Formula Used:
[tex]Amount=P(1+\frac{r}{n} )^{nt}[/tex]
Substitute the values in the above formula
[tex]Amount=3100(1+\frac{3.6}{100} )^{19}[/tex]
[tex]Amount=[/tex]$6070
Hence, there will be $6070 in account after 19 years.

Martin has 60 magazines and 42 books to put into stacks. Each stack will have 7 magazines and 4 books. How many complete stacks of 7 magazines and 4 books can Ms. Martin make?
Answer:
8 complete stacks
Step-by-step explanation:
Total magazine = 60
Total books = 42
Each stack will have 7 magazines and 4 books.
Each stack = 7 magazines + 4 books
How many complete stacks of 7 magazines and 4 books can Ms. Martin make?
Number of stack of 7 magazines possible = total magazines / magazines per stack
= 60/7
= 8 4/7
Complete stacks with 7 magazines = 8
Number of stack of 4 books possible = total books / books per stack
= 42/4
= 10 1/2
Complete stacks with 4 books = 10
If 7 magazines on each stacks can make 8 complete stacks
Then, 4 books on each stack can make 8 complete stacks
Note: after 8 stacks using 7 magazines each, magazines will not be available to complete other stacks
