2. The tread life of a tire is normally distributed with a mean of 70,000 miles and a standard deviation of 1,500 miles. What is the probability that the tire will last less than
72,000 miles?
A. 90%
B. 11%
C. 14%
D. 15%

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
