|x+3|=2 1/4
what is X

x = -3/4                       x = -5 1/4

Step-by-step explanation:

|x+3|=2 1/4

When we have an absolute value equation we have two solutions one positive and one negative.

x+3 = 2 1/4     and x+3=-2 1/4

Subtract 3 from each side

x+3-3 = 2 1/4 -3      x+3-3 = -2 1/4 -3

x = -3/4                       x = -5 1/4

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
