Edgar ran e meters per second, and Mathieu ran m meters per second. The boys ran for t seconds. The expression t(m-e) describes how many more meters Mathieu ran than Edgar ran during that time. We can also use the expression tm-te to represent the same quantity. Match each amount in the situation with the expression that represents it.

I try to do it but I don't know if is right...

you first to choose the points and then move from then as the slope you have

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200
