Answer from: Geo777

To solve this, we can start by finding a general equation and then solving for r, or the amount of raspberries (in pounds). To find the general equation, we start with 24 as the amount of dollars. As we have the cost of apples as 4$ per pound, we must add 4 dollars for every pound and therefore multiply 4 by the amount of apples, or a. Similarly, we must multiply 6 by the amount of raspberries. So, as we know that 24 dollars equals the amount of some amount of apples and some amount of raspberries, we can write our original equation as 24=4*a+6*r. Next, using the additive property of equality, we can subtract 24 from both sides to get 0=4*a+6*r-24. This helps us isolate r, as we can then subtract 6r from both sides to get -6r=4*a-24. Similarly, as -6r/-6=r, we can divide both sides by -6 to get r=(-4/6)a-(-24/6)=(-4/6)a+4, making our answer a.

Answer from: Quest

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
