Solve the problem by writing and solving a suitable system of equations.
if 20 pounds of tomatoes and 10 pounds of bananas cost $17 and preview of tomatoes and preview of bananas cost $39, what is the price per pound of tomatoes and bananas?
tomatoes: $0.70 per pound; bananas: $0.30 per pound
tomatoes: $0.50 per pound; bananas: $0.70 per pound
tomatoes: $0.60 per pound; bananas: $0.50 per pound
tomatoes: $0.70 per pound; bananas: $0.50 per pound

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."

i wish i could you, i have no idea how to answer this
