X would equal 18 when y equals 12.

Since x equals 12 when y=8, you can write it as 8/12

Then it says when y = 12 what is x, well you divide 12 and 8 to get 1.5 then multiply 12 and 1.5 to get what x equals when y is equal to 12.

Correct me if I am wrong.

Given that:

James is 6 times older than his friend Zach, if Zach added 8 to his age and multiplied this sum by 3 .

To find:

The equation that can be used to solve for zach's age.

Solution:

Let the age of zach be Z.

Zach added 8 to his age = Z+8

And multiplied this sum by 3 = 3(Z+8)

James is 6 times older than his friend Zach = 6Z

Now,

6Z=3(Z+8)

6Z-3Z=24

3Z=24

Divide both sides by 3.

Z=8

Therefore, the required equation is 6Z=3(Z+8) is age of zach is 8 years.

Question #3: Complete the statement below to show the correct value of 100%. Part A: The expression 100 3 = 10 because 100 = 102
BigorU [14]

Answer:

Step-by-step explanation:

Part A.

Expression (100)^{\frac{1}{2}} = 10

Because 100 = (10)^{2} and [(10)^2]^{\frac{1}{2}}=10^1=10

[Since, (a^{2})^{\frac{1}{2}}=a^{2\times \frac{1}{2}}=a^1]

Part B.

When simplified, the answer is RATIONAL.

[Since, 10 can be written as \frac{10}{1}]

Mr. Babe used to work at a local furniture store.
8090 [49]

A. Mr. Babe made a commission of $14.85

B. He makes $15.75 per hour after the raise.

Step-by-step explanation:

A. While he worked there, Mr. Babe earned 3% on how much he sells. If he sold $495 couch, how much commission did he make?

Worth of sold couch = $495

Commission = 3%

Amount of commission = 3% of total worth sold

Amount of commission = \frac{3}{100}*495

Amount of commission = \frac{1485}{100}=\$14.85

Mr. Babe made a commission of $14.85

B. On top of his commission, Mr. Babe made $15 per hour. He eventually got a raise with an increase of 5% per hour. After the raise, how much did he make per hour?

Amount earned per hour = $15

Increase = 5%

As the increment is on per hour amount, therefore,

Amount of increase = 5% of per hour amount

Amount of increase = \frac{5}{100}*15=\frac{75}{100} = \$0.75

New amount per hour = Per hour amount + amount of increase

New amount per hour = 15+0.75 = $15.75

He makes $15.75 per hour after the raise.
