Question

Answer the following. a) Find h b) Find x

Answer 1

a) h = 15

b) x = 4

Explanation:

a) set up a proportion:

5 = h

8 24

cross-multiply:

8h = 120

h = 15

b) x + 5 = x + 5 + 15

5x + 1 5x + 1 + 35

cross-multiply:

(x + 5)(5x + 36) = (5x + 1)(x + 20)

5
`x^(2)` + 61x + 180 = 5
`x^(2)` + 101x + 20

180 = 40x + 20

160 = 40x

x = 4
