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.

**Principa**l 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=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

Fernando has a bucket that holds 3 gallons of water.he is filling the bucket using a 1-pint container.how many times will he have to fill the pint container in order to fill the bucket

Solution 1

48 times he will need to fill the pint container.

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

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)

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 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(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.
