Aubrey's scarf is 4 inches more than half the length
of Tyrone's scarf. Aubrey's scarf is 34 inches long.
How long is Tyrone's scarf?

Tyrone's scarf s 60 inches long.

Step-by-step explanation:

If Aubrey's scarf is 34 inches long and its 4 inches more than half of Tyrone's scarf then we can subtract 4 from 34 to find half of Tyrone's scarf then we multiply 30 times 2 to find the length of Tyrone's scarf.

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.
