The price of a gallon of gasoline is 3.16 the price when ryan’s mother started driving was 1/4 of the current price what was the price of gasoline when ryan’s mother started driving

"of" means multiply, "was/is" means equals

started driving price      was     1/4      of      current price

                    ?                  =          1/4      x        3.16

                    ?                  =          3.16/4

                    ?                  =           .89

$0.89

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

cosine
