Let the number be x
(3/7) x = t
I can't think of anything useful to add to this. How about an example?
Let x = 49
(3/7) x = t
(3/7) * 49 = t seven will go into 49
3 * 49 = t
t = 147
(3/7) x = t

Question
Amy has for gerbils Which Way 20 G 22 G 24 and 26 G what is the total weight of the gerbils in milligrams
Solution 1
First, I'll translate the problem into English:
Amy has four gerbils whose masses are 20 g, 22 g, 24 g, and 26 g.
What is the total mass of the gerbils in milligrams?
First add the masses in grams:
20 g + 22 g + 24 g + 26 g = 92 g
Now convert grams into milligrams.
1 gram = 1000 milligrams
92 g * 1000 = 92,000 mg
Answer: The total mass is 92,000 mg.

Question
How do i simplify 40 15×40 2
Solution 1
I am going to assume that you meant 40(15 x 40)2,, but if not then please let me know and I will fix my answer for you.
The first step for solving this is to multiply the numbers in the parenthesis.
40 x 600 x 2
Now multiply the first two numbers together.
24000 x 2
Multiply the final two numbers together to get your answer.

Question
Emilio borrows $1200 from a bank with 8% simple interest per year. How much interest will he have to pay back in 2 years?
Solution 1
The interest per year on the amount of money that Emillio borrowed from the bank at the rate of 8% interest is $192
- Interest can be regarded as the charges that is added to the principal, usually some percentage of the principal.
- Principal is the amount of money that is been lent out.
- Rate can be regarded as the percentage increase of the principal.
- Time (t) can be regarded as the period that is needed to pay the money that was lent out back.
- were were given rate (r) as
%
- with
as ?
From the the formula for expressing
- Then substitute into the formula
Therefore, the interest on the money is $192

Solution 2
Simple Interest equation is I=p×r×t
P= is the principal amount (1200)
R= is the interest rate per year (8% or 0.08)
T= time in years (2)
I= 1200 × 0.08 × 2= 192.00
Interest is 192.00
P= is the principal amount (1200)
R= is the interest rate per year (8% or 0.08)
T= time in years (2)
I= 1200 × 0.08 × 2= 192.00
Interest is 192.00

Question
solve the equation. choose the answer in simplest form. 4x= 8/7 (A) 1/28 (B) 1/7 (C) 2/7 (D) 7/2
Solution 1
4x=8/7
x=(8/7)÷4
x=2/7
x=(8/7)÷4
x=2/7
Solution 2
4x = 8/7
/4 /4
x = (8/7)/4 (Keep, change, flip)
x = 8/7 * 1/4
x = 8/28
x = 2/7
/4 /4
x = (8/7)/4 (Keep, change, flip)
x = 8/7 * 1/4
x = 8/28
x = 2/7
Question
The width of a rectangle is twice it’s height if the perimeter is 54 inches find the area
Solution 1
The area is 162.
You can get this by solving for the sides. One side will be 9 and the other will be 18. This is because the perimeter must be 6x since one side is x and the other would be 2x.
You can get this by solving for the sides. One side will be 9 and the other will be 18. This is because the perimeter must be 6x since one side is x and the other would be 2x.
Solution 2
Let the height be x.
⇒ Height = x
The width of a rectangle is twice it’s height.
⇒ Width = 2x
Perimeter = 54
⇒2 (x + 2x) = 54
Solve x:
2 (x + 2x) = 54
Combine like terms:
2 (3x) = 54
Distribute 2:
6x = 54
Divide both sides by 6:
x = 9
Height = x = 9
Width = 2x = 2(9) = 18
Area = 9 x 18 = 162 in²
Answer: 162 in²
⇒ Height = x
The width of a rectangle is twice it’s height.
⇒ Width = 2x
Perimeter = 54
⇒2 (x + 2x) = 54
Solve x:
2 (x + 2x) = 54
Combine like terms:
2 (3x) = 54
Distribute 2:
6x = 54
Divide both sides by 6:
x = 9
Height = x = 9
Width = 2x = 2(9) = 18
Area = 9 x 18 = 162 in²
Answer: 162 in²
Question
What is the length of the diagonal of a square with 8 foot sides?
Solution 1
Using the Pythagorean Theorem,
a² + b² = c²
c² = 8² + 8²
c² = 64 + 64
c² = 128
c = √128
c =8√2 (radical form) or 11.31 feet (nearest hundredth)
Answer: 11.31 feet
a² + b² = c²
c² = 8² + 8²
c² = 64 + 64
c² = 128
c = √128
c =8√2 (radical form) or 11.31 feet (nearest hundredth)
Answer: 11.31 feet
Question
A library is open til' 5:00 P.M. On Wednesdays, the library closes 2 hours early. How many hours for a month is the library open.
Solution 1
So
if you assume that the month has 30 days and that the library opens at midnight, then
24 hours in a day
5 pm=12+5=17 hours
on wednessday=17-2=15 hours
wednessday=1/7 of week
so we find 1/7 of 30 which is 30/7=4 and 2/7
then subtract that from 30
30-4 and 2/7=25 and 5/7
ok so then we have
25 and 5/7 days is 17 hours and
4 and 2/7 days is 15 hours
so just multipy them and add
25 and 5/7 times 17=437.143 hours
4 and 2/7 days times 15 =64.2857
add
437.143+64.2856=501.429
so aprox 501.429
the real equation is![[(\frac{1}{7})(n)(15)]+[ (\frac{6}{7}) (n)(17)]=hours](https://tex.z-dn.net/?f=%5B%28%5Cfrac%7B1%7D%7B7%7D%29%28n%29%2815%29%5D%2B%5B%20%28%5Cfrac%7B6%7D%7B7%7D%29%20%28n%29%2817%29%5D%3Dhours "[(\frac{1}{7})(n)(15)]+[ (\frac{6}{7}) (n)(17)]=hours")
where n represents the number of days in the month

Question
How do i solve 3 (2y-4)=8y+9-9y
Solution 1
3(2y - 4) = 8y + 9 - 9y
Distribute 3:
6y - 12 = 8y + 9 - 9y
Combine like terms:
6y - 12 = -y + 9
Add y to both sides:
7y - 12 = 9
Add 12 to both sides:
7y = 21
Divide both sides by 3:
y = 3
Distribute 3:
6y - 12 = 8y + 9 - 9y
Combine like terms:
6y - 12 = -y + 9
Add y to both sides:
7y - 12 = 9
Add 12 to both sides:
7y = 21
Divide both sides by 3:
y = 3
Solution 2
The first step for solving this equation is to distribute 3 through the parenthesis.
6y - 12 = 8y + 9 - 9y
Collect the like terms with y.
6y - 12 = -y + 9
Move the variable to the left side and then change its sign.
6y + y - 12 = 9
Now move the constant to the right side and change its sign.
6y + y = 9 + 12
Add the terms on the left side of the equation.
7y = 9 + 12
Add the numbers on the right side.
7y = 21
Lastly,, divide both sides of the equation by 7 to find your final answer.
y = 3
This means that y = 3 is the correct answer to your question.
Let me know if you have any further questions.
