A group of seven adults went to the movies. The total cost of the movie tickets was $30. This doesn't seem possible, does it? Af
Artyom0805 [142]

Answer:

no. of senior citizens=x

no.of other people=7-x

cost=30=k(7-x)+(k/2)x. k is the cost of a ticket

k(7-x+x/2)

k(7-x/2)-30=0

k=60/(14-x)

now do trial and error substitution for (x<7) until u get a whole number for k also (k<30). if you have the skills you can suggest the number yourself

ie x= 2, k=5$

Solve the expression for x: (4-2)(x-2)=4x-8
ivann1987 [24]
First, distribute the left side. You should get 4x-8-2x+4=4x-8. Then, get all the xs on one side.

4x-2x-4x-8+4=-8

Then, put the numbers on one side.

4x-2x-4x=-8+8-4

Then, add it up.

-2x=-4

Then, solve for x.

(-2x)/(-2)=(-4)/(-2)

x=2

Hope that helps!
