use the model to solve for x. (model above)

a) x=2
b) x=4
c) x=8
d) x=12

A

Step-by-step explanation:

Convert the symbols in the diagram to an algebraic equation

3x + 6 = 5x + 2 ( subtract 3x from both sides )

6 = 2x + 2 ( subtract 2 from both sides )

4 = 2x ( divide both sides by 2 )

2 = x ⇒ x = 2 → A

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

the answer

b. they are parallel and will never intersect.
