At a lunch buffet, the price for an adult plate is $19, and the price for a child plate is $8. On Tuesday, a total of 32 plates
mestny [16]

Answer:

Adult plate = 21 , child plate = 11

Step-by-step explanation:

number of adult plate = a , no of child plate = c

$487 = $19a + $8c (equation 1)

32 = a + c (equation 2)

Multiply equation 2 by 8 gets you:

256 = 8a + 8c (equation 3)

Solve equation 1 and equation 3 simultaneously:

487 = 19a + 8c (equation 1) minus

256 = 8a + 8c (equation 3) :

231 = 11a

a = 231/11

a= 21

Substitute a = 21 into equation 2 :

32 = 21 + c

c = 32 - 21

c = 11

So 21 adult plates and 11 child plates were sold.

What is x? Show your work.
dedylja [7]

Answer:

x=5.75

Step-by-step explanation:

As you can see, EH and FG are congruent, which means that the measurements must be the same.

You have 4x+5=28

That's already an equation! Now you solve it:

4x+5=28

4x=28-5

4x=23

x=5.75
