N5 years, dad will be three times as old as his daughter jill will be then. if the sum of their present ages is 50, how old are they now? if y + 5 is jill's age five years from now, which of the following equations could be used to solve the problem?

150

Step-by-step explanation: you have to multiply 50 and 3 and the answer is 150

- "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."

answer: i literally just answered this question but they want me to do it again
