I think 28 or probably 79 maybe the both
Answer:
P = 33z + 3
Step-by-step explanation:
To find the perimeter (P) sum the 4 sides
P = 8z - 3 + 10z - 3 + 6z - 1 + 9z + 10 ← collect like terms
= (8z + 10z + 6z + 9z ) + (- 3 - 3 - 1 + 10)
= 33z + 3
Answer:
The cost of parts was $65.
Step-by-step explanation:
Let the cost of parts = x
35 + 21(3) + 1.10x = 169.50
98 + 1.10x = 169.50
71.50 = 1.10x
71.50/1.10 = 65
