Sonia opened a savings account and then added the same amount to the savings account every week. After weeks, her savings account had a total of . After weeks, her savings account had a total of . Which equation represents the amount of money in dollars, in Sonia’s savings account after weeks?

what was the total it will not be able to be answered without a given number to solve

answer: i guess 105 degrees?

step-by-step explanation:

- "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."
