A group of 64 children and 24 adults will travel to a zoo in vans. There will be 8 people in each van. How many vans will be needed to take the group to the zoo

11

Step-by-step explanation:

Given that :

Number of adults = 24

Number of children = 64

Number of people per van = 8

Number of vans required :

Total number / number per van

(64 + 24). / 8

= 88 / 8

= 11 vans

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.
