Answer:

Step-by-step explanation:

Paul: 140 + 12x

Jacklyn: 56 + 16x

Where x is how many practice sessions he had this season

"After how many more practices will Paul and Jacklyn have completed the same number of laps?"

This means what will x be if both equations are equal to each other

140 + 12x = 56 + 16x

Isolate x in one side by subtracting both sides by 12x

140 + 12x - 12x = 56 + 16x - 12x

140 = 56 + 4x

Subtract both sides by 56 to shift the 56 from the right side to the left side

140 - 56 = 56 - 56 + 4x

84 = 4x

Divide both sides by 4 to isolate x

84/4 = 4/4x

21 = x

x = 21

They'll have completed the same number of laps after 21 practices

Hope it helps :)

Two-thirds of the students in a class are wearing blue jeans.Two-sixths of the students who are wearing blue jeans are also wear

Vesnalui [34]

Given Two-thirds of the students in a class are wearing blue jeans

.Or $\frac{2}{3}$ Of students wear blue Jeans.

Number of students wearing red shirts is Two-sixths of the students who are wearing blue jeans .

Number of students wearing red shirts = $\frac{2}{6} of\frac{2}{3}$

Simplifying we have:

$\frac{2}{6} of\frac{2}{3} =\frac{4}{18} = \frac{2}{9}$

Fraction of the students in the class are wearing blue jeans red shirts = $\frac{2}{9}$
