Arecipe requires 12 cups of flour. you can only measure using 2/3 cups.
how many 2/4 cups are needed for this recipe?

18 cups

Step-by-step explanation:

I assume that the part about 2/4 is an error that really means 2/3.

All you need to do is divide 12 by 2/3. Since you can't divide by a fraction, you have to multiply by its reciprocal, 3/2. You get 36/2, or 18.

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
