Answer:
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
