Wich expression is equivalent to 1/2 x+ + (-7) -2 1/4 x -(-2)

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.

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.

step-by-step explanation:

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
