What is the value of the expression?
(-2.5)(1.15)(-0.5)

1.4375

Step-by-step explanation:

-2.5 * 1.15 = -2.875

-2.875 * -0.5 = 1.4375

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.

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
