of the 20 families she surveyed, 18 of them recycle. About how many families in her
neighborhood recycle?

225

Step-by-step explanation: 250 / 20 is 12.5 and 12.5*18 is 225

225

Step-by-step explanation:

According to the givens, these 20 families represent a sample of all.

18 of 20 is 90%, which means that if this sample represents all families correctly, 90% of 250 families recycle, which is 225 families.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
