Answer 2

Answer:

8, option c

9, option a

10 option c

Step-by-step explanation:

8).

(1/5)x - 4 = 3

(1/5)x = 3+4

(1/5)x = 7

x = 35

option c

9)

9+ 3x = 45

3x = 45-9

3x = 36

x= 12

option a

10)

(4/5)x greater than (3/4)x

difference by 4

(4/5)x - (3/4)x= 4

take lcm

(16-15)/20 * x = 4

(1/20)x = 4

x = 4*20

X = 80

option c
