Answer:

72 ads

Step-by-step explanation:

Let

x -----> the number of ads

we know that

5 sheets of construction paper for a title banner plus the number of ads multiplied by one quarter of sheet must be equal to 23 sheets of construction paper

so

The linear equation that represent this problem is

\frac{1}{4}x+5=23

Solve for x

Multiply by 4 both sides to remove the fraction

x+20=92

Subtract 20 both sides

x=92-20

x=72\ ads

lyudmila [28]

Answer:

5 months

Step-by-step explanation:

To solve this problem, we need to create and algebraic equation for when Jill's weight will be equal to Paris's. If we take their current weight and then add the additional weight gain per month times the number of months, we can calculate the amount of time it will take for their weight to be equal by solving for m.

120+10m=150+4m\\10m-4m=150-120\\6m=30\\m=5

A ferry takes several trips between points A and B. It moves at a constant speed of 0.35 miles/minute and takes the same route o
Fofino [41]

The answer is  -|0.35 t -14| +14

<u>Step-by-step explanation</u>:

The problem statement is asking for an expression for distance in miles, so the constants in the expression will be miles. In the time it takes to get to point B (40 minutes), the ferry has gone (0.35 mi/min)×(40 min) = 14 mi. Hence the maximum value of the function must be 14. The only function with that characteristic is the one of selection D.
