Which of the following inequalities is equivalent to 3-(w+2)>4+2w

Kay [80]

$3 - w - 2 > 4 + 2w \\ - w - 2w > 4 + 2 - 3 \\ - 3w > 6 - 3 \\ \frac{ - 3w}{ - 3} > \frac{3}{ - 3} \\ w < - 1$
The sign at the end changes because both sides of the equation are being divided by a negative number.

Answer:

A. (f-g)(x) = -7x -3

mr Goodwill [35]

Total people in the cafeteria = 7 + 48 + 45 = 100

There are 45 boys.
