A piece of string is 5 5/8 inches long. How much should Lena cut off to make it 3 1/2 inches long?
solong [7]

Answer:

2 1/8 inches

Step-by-step explanation:

First, we make the fractions into improper fractions:

5 5/8 = 45/8

3 1/2 = 7/2

Now we make them to have the same denominator

7/2 = 28/8

Now we substract

45/8 - 28/8 = 17/8

17/8 =  2  1/8 inches

Adult tickets to the fall play cost $8
iren2701 [21]

Solving a system of equations we will see that they sold 80 adult tickets.

<h3>how many adult tickets were sold?</h3>

To solve this, we need to solve a system of equations. To define said systems of equations, we first need to define the variables, we will use:

  • x = adult tickets sold.
  • y = student tickets sold.

They sold 20 more adult tickets than student tickets, then:

x = y + 20

And they collected a total of $880, then:

x*$8 + y*$4 = $880

The the system of equations is:

x = y + 20

x*$8 + y*$4 = $880

Isolating y on the first equation we get:

y = x - 20

Replacing that on the other equation we get:

x*$8 + (x - 20)*$4 = $880

Now let's solve that for x.

x*$12 - $80 = $880

x*$12 = $880 + $80 = $960

x = $960/$12 = 80

They sold 80 adult tickets.
