Lindsey, Laurie, and Mike showed their work solving the equation -3.3 + 73 - 5 = 8. Identify the student with the invalid first step and (justify your reasoning)

Laurie - 3x + 7x - 5 = 8
-3x + 7x - 5 = 8

Lindsey -3x + 7x – 5 = 8
-3x + 7x = 13

mike -3x + 2x = 8
4x - 5 = 8

correct

step-by-step explanation:

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

where are the choices?

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
