Can someone answer this question please?

Step-by-step explanation:

In this problem, we have:

is the number of french fries in the lunch

is the number of chicken wings

Each french fry has 25 calories

Each chicken wing has 100 calories

Therefore, the total amount of calories absorbed in one lunch is given by:

Here we want the total calories absorbed in the lunch to be less than 500 calories.

Therefore, the inequality can be written as:

- "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."
