Help! I’ll mark list

a = 40

t = 1

x = 6

x = 11

Step-by-step explanation:

1.

3/8 = 15/a

multiply both sides by a, then multiply by the reciprocal of 3/8

a = 8*15/3

2.

multiply both sides by 2

t = 1

3.

multiply both sides by 5

x - 3 = 30/10

x = 6

4.

multiply both sides by x - 5, then multiply by the reciprocal of 10/15

60/10 = x - 5

x = 6
