What is the first step in solving for the solution to this problem?

2(m + 10) = 4(m -15)

Multiplying the variables and numbers in the parentheses by the number next to them.

Step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

answer: f = 32.2m

step-by-step explanation: that is the answer
