37 ! a group of adults plus one child attend a movie at a movie theater. tickets cost $10 for adults and $5 for children. the total cost for the movie is $85. enter an equation to find the number of adults in the group.

8 adults

Step-by-step explanation:

The proper equation to find the number of adults is as follows...

(1 x 5) +(10x) = 85

Since there is only one child will will have 1 ticket for a child. hint ( 1 x 5)

Since we need to find the total number of adults at the movie group we will put (10x)

Since the total cost is 85 we will have it equal to $85

Now time to solve

5 + 10x = 85

first subtract 5 from both sides ( 5 - 5 ) and ( 85 - 5 )

10x=80

Now divide both sides by 10 ( 10x/10 ) and 80/10

x=8

So there are 8 adults.

D. (x+2)(-8x+70)

Step-by-step explanation:

-8x^2+54x+140

Factor out -2

-2(4x^2+27x+70)

Factor

-2(x+2)(4x-35)

Option D is the same answer if we multiply -2 in the second term

(x+2) (-8x+70)
