We can use ratios and the cross-multiply-divide to find this.
The ratio 21:5 is avaliable via the question. We then need to compare that to the ratio x:100, the 100 being the percent and the x being the number of airplane parts.
21/5 = x/100
We can then solve for x to find the number of airplane parts. First we multiply by 100 on both sides to get 2100/5 = x. Therefore x = 420 and there are 420 airplane parts.
Answer:
9d+3
Step-by-step explanation:
(6d+5)-(2-3d)= cancel out parentheses
6d+5-2+3d= Commutative property of addition
6d+3d+5-2= Group like terms
(6d+3d)+(5-2)= Combine like terms
Answer = 9d+3
