Answer:

Step-by-step explanation:

y=0.5x+15

We are told she earned $16.50 so

0.5x+15=16.5, subtract 15 from each side

0.5x=1.5, divide each side by 0.5

x=3

So she fixed three computers.

Answer:

\frac{31x-159}{168y}

Step-by-step explanation:

\frac{x-4}{7y} - \frac{x+7}{8y} + \frac{x+3}{6y}

the LCD of the denominators is 168y , then

\frac{24(x-4)-21(x+7)+28(x+3)}{168y} ← distribute and simplify numerator

= \frac{24x-96-21y-147+28x+84}{168y}

= \frac{31x-159}{168y}

Gina has a $50 gift card to a bagel shop. Each Friday, she purchases breakfast for $6. She created a graph to represent the amou
Ghella [55]

Answer:

No, because the amount of money on her gift card should decrease each week.

Step-by-step explanation:

Well, the graph shows that the slope is increasing, if you got $50.00 and spend $6.00 each Friday, wouldn't that be  decrease and not increase? This is why we eliminate the yes options. Lastly, of course, they should not start at the origin as they started at $50.00.

Proof I got it correct:

If we use the width as x we have 2x with both widths and 4x with both lengths. So 6x=24 and x=4. So length is 8 and width is 4.
