If Jennifer doubled the money that she has in her account now and then took out $50, she would have enough left in her account to buy a new bike that costs $299. Write and solve an equation to determine how much money Jennifer has now.

Something like 2x-50 $299

Step-by-step explanation:

Because when she doubles the number, that means it is multiplied by 2, but the number she has is unknown, so it's x. Then she takes $50, which means you have to subtract from the 2x. I put the because technically, the variable could be any number and you could still buy the $299 bike. But if you want an exact answer for the x would be $174.50. :)

step-by-step explanation:

.6 is 1/2 of 12

the answer is actually d. i just took the test

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
