Given :

Emily sells erasers for $2 per package and pencils for $5 per package. she sells 220 total packages and earns $695.

To Find :

The number of packages of erasers and pencils that were sold .

Solution :

Let, number of erasers are x and pencils are y.

So, x + y = 220    ....1

Also, 2x + 5y = 695   ....2

Solving equation 1 and 2, we get :

2(220-y)+5y = 695\\\\440 - 2y + 5y = 695\\\\3y = 255\\\\y=85

x = 220 - 85 = 135

Therefore, the number of packages of erasers and pencils that were sold are 135 and 85 respectively.

Hence, this is the required solution.

For math Equations what is 4x + 5 = x + 8??
vfiekz [6]

Answer:

x = 1

Step-by-step explanation:

To solve for a variable, you need to get the variable on one side of the equation, and by itself.

4x + 5 = x + 8

4x = x + 3 --- subtract 5 from both sides

3x = 3 --- subtract x from both sides

x = 1 --- divide both sides by 3

A rectangular prism has a volume 144 centimeters. The base is a square with a length of 4 cm. What is the height of the prism?
Vitek1552 [10]
The volume is the product of the height and the area of the base.
  V = Bh
The area of the square base is (4 cm)² = 16 cm², so the height can be found from
  144 cm³ = (16 cm²)h
  h = (144 cm³)/(16 cm² = 9 cm

The height of the prism is 9 cm.

6. A pizza's original price is $11. It is on sale for $9.25. What percent off is it?
wolverine [178]

Solution:

<u>We know that:</u>

Original \ price = \$11

Sale \ price = \$9.25

\frac{9.25}{11} + \frac{1.75}{11} =100\%

<u>Simplify the equation to find the percent off:</u>

\frac{9.25}{11} + \frac{1.75}{11} =100\%

84\% + \bold{16\%} = 100\% \space\ \space\ \space\ \ \ \ \ [Rounded]

This means that the <u>original price</u> has decreased about 16%.
