Answer:

x = -9

Step-by-step explanation:

Let's solve your equation step-by-step.

−2(6+2x)+2x−12=−6

Step 1: Simplify both sides of the equation.

−2(6+2x)+2x−12=−6

(−2)(6)+(−2)(2x)+2x+−12=−6(Distribute)

−12+−4x+2x+−12=−6

(−4x+2x)+(−12+−12)=−6(Combine Like Terms)

−2x+−24=−6

−2x−24=−6

Step 2: Add 24 to both sides.

−2x−24+24=−6+24

−2x=18

Step 3: Divide both sides by -2.

−2x

−2

=

18

−2

x=−9

Answer:

x = -9

Step-by-step explanation:

-2(6 + 2x) + (2x - 12) = -6

Distribute

-12 -4x +2x -12 = -6

Combine like terms

-24 -2x=-6

Add 24 to each side

-24+24 -2x= -6+24

-2x = 18

Divide by -2

-2x/-2 = 18/-2

x = -9

Answer:

17. See below

18. 750

Step-by-step explanation:

17. Since the lollipops are being sold at the same price, 50 cents, for each one sold, they make a constant amount of money. For each increase in lollipops sold, there is a constant increase in money made, and thus the situation is a linear function.

18. To solve this equation, let's say y is the money made at the convention in dollars and x is the number of lollipops sold. If the principal gave them 125 dollars before they sold any lollipops (0 lollipops sold), then 125 is the y-intercept of the function, and in the equation y=mx+b, b=125. If each lollipop costs 50 cents (half of a dollar), then for each lollipop, x, sold, .5 dollars are made and are added to the profit, y. Thus, .5 dollars is the slope. The equation then becomes:

y=0.5x+125

Now, if they need 500 dollars, y is thus equal to 500 dollars. Solving the equation:

500=0.5x+125

500-125=0.5x

375=0.5x

\frac{375}{0.5} =x

375*2=x

750=x

Thus, 750 lollipops must be sold.
