At practice, Diego does twice as many push-ups as Noah, and also 40 jumping jacks. He does 62 exercises in total. The equation: 2x + 40 = 62 describes this situation. What does the variable x represent?

Step-by-step explanation:

x = number of pushups he did

the number of pushups done by Noah

Step-by-step explanation:

if Noah did x amount of pushups then Diego did twice as many, which is 2x therefore in this equation x represents the number of pushups done by Noah

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
