Question
How would you find the number, 3/7 of which is equal to t? (let's say it was any number, just need the equation)
Solution 1
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 = 147Â
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 15Ã—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
48000

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 Â 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%
• withas ?

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=pÃ—rÃ—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 Ã— 0.08 Ã— 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)Ã·4
x=2/7
Solution 2
4x = 8/7
/4Â  Â  Â /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 itâ€™s height if the perimeter is 54 inches find the area
Solution 1
The area is 162.Â

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.Â
Solution 2
Let the height be x.
â‡’ Height = x

The width of a rectangle is twice itâ€™s height.
â‡’ Width = 2x

Perimeter = 54
â‡’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 inÂ²

Question
What is the length of the diagonal of a square with 8 foot sides?
Solution 1
Using the Pythagorean Theorem,Â

aÂ² + bÂ² = cÂ²

cÂ² = 8Â² + 8Â²

cÂ² = 64 + 64

cÂ² = 128

c =Â âˆš128

c =8âˆš2 (radical form) orÂ Â 11.31 feet (nearest hundredth)

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

437.143+64.2856=501.429
so aprox 501.429

the real equation isÂ  where n represents the number of days in the month

apros 501.429
Question
How do i solve 3 (2y-4)=8y+9-9y
Solution 1
3(2yÂ -Â 4)Â =Â 8yÂ +Â 9Â -Â 9y

DistributeÂ 3:
6y - 12 = 8y + 9 - 9y

Combine like terms:
6y - 12 = -y + 9

7y - 12 = 9Â

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.
