Step-by-step explanation:

please give me brainlest

65

Step-by-step explanation:

2 + 7 (-3)^2

= 2 + 7 (9)

= 2 +63

= 65

Just remember to do the ones in the bracket first, and keep an eye on your negatives and positives

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.

on your paper it doesn't say the answer but the the answer is altitude
