Answer:

15% of 30 = 4.5

30% of 45= 13.5

60% of 7= 4.2

23% of 20= 4.6

Step-by-step explanation:

We multiply each percent amount. To remove % we divide by 100

15% of 30

15/100 * 30 = 0.15 * 30=4.5

30% of 45

30/100 * 45 = 0.30 * 45=13.5

60% of 7

60/100 * 7 = 0.6 * 7=4.2

23% of 20

23/100 * 20 = 0.23 * 20=4.6

Which of the following are inverses of each other?
Over [174]

Answer:

So, how do we check to see if two functions are inverses of each other? Well, we learned before that we can look at the graphs.

Step-by-step explanation:

Remember, if the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions.

John made $252 for 18 hours of work. At the same rate, how much would he make for 7 hours of work?
Juliette [100K]
This is basically the same as the other question you posted, just with different variables!! make another proportion

252 dollars/18 hours = x dollars/7 hours

252/18 is 14, so

14 = x dollars/7 hours

multiply both sides by 7 to isolate x

98 dollars = x

so john will make $98 for 7 hours of work

Can you show the steps on how to get the answer?
Sati [7]

Answer:

Last option; x = 1 or x = -5

Step-by-step explanation:

1. Simplify the equation.

Step 1: Add 7 to both sides.

  • 4(|2x+4|)-7+7=17+7
  • 4(|2x+4|) = 24

Step 2: Divide both sides by 4.

  • \frac{4(|2x+4|)}{4}  = \frac{24}{4}
  • |2x+4| = 6

2. Now that we simplified the equation to this, we have to solve for absolute value. We know either 2x + 4 = 6 or 2x + 4 = -6.

3. (Solving for 1st possibility)

Step 1: Subtract 4 from both sides.

  • 2x + 4 - 4 = 6-4
  • 2x = 2

Step 2: Divide both sides by 2.

  • \frac{2x}{2} = \frac{2}{2}
  • x = 1

4. (Solving for 2nd possibility)

Step 1: Subtract 4 from both sides.

  • 2x+4-4=-6-4
  • 2x = -10

Step 2: Divide both sides by 2.

  • \frac{2x}{2}= \frac{-10}{2}
  • x = -5

5. Now that we have the outcomes of both of our possibilities as x = 1 or x = -5, the last option matches with what we got.
