Write words to match the equation. b + 5 = 12

a number plus 5 equals 12.

Step-by-step explanation:

7

Step-by-step explanation:

b+5=12

subtract 5 from both sides to have b by itself.

Then, 5 will cancel 5, which will leave us with: b=12-5=7

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
