Answer:
Mac is 19 years old, Joe is 11 years old
Step-by-step explanation:
2J - 3 = M
J + M = 30
M = 30 - J
2J - 3 = 30 - J
3J = 33
J = 11
M = 30 - 11
M = 19

Hope this helps!!
Let the length of the shortest side = x
The two longer sides that are equal = 3x
The are two equal longer sides, so their total is 3x + 3x = 6x
3x+ 3x + x= 35 Collect like terms on the left
7x = 35 Divide by 7 on both sides
x = 35/7
x = 5
Answer
Two long sides -- 15 cm each
Shortest side -- 5 cm
