Annette earns a salary of $152 per week, plus a commission of $12 for each painting she sells. how many paintings must she sell in a week to earn $440?

19 paintings

Step-by-step explanation:

152+12x=440

440-152=288

288=12x

228/12

19=x

19 paintings

X=24

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

what is the model?
