Answer:

x=40

Step-by-step explanation:

The angles of both expressions (4x-28) and (3x+12) are congruent (alternating exterior angles). So, you can set up the equation 4x-28 = 3x+12 because both expressions are equivalent, so it makes sense. Then solve for x.

4x - 28 = 3x + 12

x - 28 = 12

x = 40

muminat

Answer:

k = 12

Step-by-step explanation:

The constant of proportionality k is the ratio

k = $\frac{laps}{swimmers}$

Use any ordered pair from the table to find k

Using number of laps = 240, number of swimmers = 20 , then

k = $\frac{240}{20}$ = 12
