Help with this question please . At a local market , the cost of apple is directly proportional to the weight of the apples . Carlos bought 10 pounds of apples for a cost of $15.00 .which graph shows the relationship between the weight of the apples , in pounds , and the cost of the apples , in dollars ?

A

Step-by-step explanation:

the cost and weight are directly proportional, so decreasing one decreases the other at the same rate.

ratio is cost : weight, which is 15:10. the simplest ratio is 3:2, on the graph find where the cost is 3 and weight is 2. only graph A satisfy the condition

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
