The parker family drove a total 180 miles on there road trip this distance is 1.5times the distance they drove on the first day how many times did the parker family drive in the first day ?

120 miles

Step-by-step explanation:

Let d represent the number of miles driven on the first day.  Then 1.5 times d came to 180 miles.  Dividing both sides of this equation by 1.5 to isolate d, we get:

180 miles

= 120 miles

  1.5

Thefamily drove 120 miles during the first day of their trip.

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
