It’s all about substitution, i think the answer is 2.
(2y + 5)° = 4y °
- 4y + 2y° = -5°
-2y° = -5°
y =5/2
Answer:
If the bolt is .52, it is between .517 and .583, so it can go in the package.
Step-by-step explanation:
The first step is to determine what the error amount is
6% of .55
.06*.55 =.033
The bolt must be within .033 of .55
.55 - .033 = .517
.55 + .033 = .583
The bolt must be between .517 and .583 inches
If the bolt is .52, it is between .517 and .583, so it can go in the package.
