amount of money Eric has, y, and the amount of hours he has worked, x?
A. y = 30x + 9
B. y = 9x - 30
C. y = -9x + 30
D. y = 9x + 30

Answers

Answer:

D. y = 9x + 30.

Eric has thirty dollars when he starts, so he would be adding 30, and since he makes 9 dollars an hour, it would be 9x. therefore the answer is 9x + 30

Answer:

x < -7 or x > 13

Step-by-step explanation:

3 - x < -10 or 3 - x > 10

-x < -13      or    -x > 7

x > 13         or    x < -7

Answer: x < -7 or x > 13

Answer:

x < -7 or x > 13

Step-by-step explanation:

Solving Absolute Value

[tex]|-x+3| > 10[/tex] We know that either -x + 3 > 10 or -x + 3 < -10

Possibility 1:

Step 1: Subtract 3 from both sides.

[tex]-x + 3-3>10-3[/tex] [tex]-x > 7[/tex]

Step 2: Divide both sides by -1.

[tex]\frac{-x}{-1} > \frac{7}{-1}[/tex] [tex]x < -7[/tex]

Possibility 2:

Step 1: Subtract 3 from both sides.

[tex]-x + 3 - 3 < -10 - 3[/tex] [tex]-x < -13[/tex]

Step 2: Divide both sides by -1.

[tex]\frac{-x}{-1} < \frac{-13}{-1}[/tex] [tex]x > 13[/tex]

Therefore, the answer is x < -7 or x > 13.

Answer: The triangles are not congruent.

Step-by-step explanation:

Fran has raised 2/9 of her fundraising goal for a charity drive. If she has raised $40, then how much money is Fran’s goal for the charity drive?

Answers

Answer:

180

Step-by-step explanation:

Fran raised 2/9 of her goal already meaning you can divide 40 by two so that you can see what 1/9 of her goal was.

40/2 = 20 (which means that is what 1/9 of her goal is)

Now what you can do is multiply 20 by 9 because when you multiply 1/9 times 9, you get one, which means the fraction is complete.

20 times 9 = 180

Her goal is to raise $180

***you can also double check if the answer is correct if you divide 2/9 and 40/the answer you get. If they match, you got the right answer! both 2/9 and 40/180 equal .22222!
