You have 12 balloons to blow up for a party. you blow up of them, and your friend blows up 5 of them. what fraction of the balloons still need blowing up?

7/12

Step-by-step explanation: you have 12 in all then your friend blows up 5 12-5=7 so you still have to blow up 7 out of 12

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

it would take 7/10 of an hour too fill the pool.
