An employee makes an hourly rate plus any tips they earn. This tip employee made a total of $400 by working 28 hours last week. If $253 of their total earnings was their tips, what is their hourly rate of pay?

Answers

To find the answer we must remove the tips amount from the total amount, and then divide what remains by the numbers of hours he worked. So we have: HourlyRate = (400 - 253) / 28 <=> HourlyRate = 147/28 <=> HourlyRate = $5.25

5/3x=10 solve equation

Answers

if yo meant 5/(3x)=10 go to A
if you ment (5/3)x=10 go to B

A
times 3x both sides
5=30x
divide both sides by 30
5/30=x
1/6=x

B
if yo meant
(5/3)x=10 then
times 3/5 both sides
x=30/5
x=6

if 5/(3x)=10, x=1/6
if (5/3)x=10, x=6

Answer: Choice A) -4, -2, 0, 2

Explanation:

This is because we are adding the same thing to each term to get the next term. That is the common difference d = 2

second term = (first term)+d = -4+2 = -2
third term = (second term)+d = -2+2 = 0
fourth term = (third term)+d = 0+2 = 2

Answers

The number should be multiply is 10.

What is multiplication?

In math, to multiply means to add equal groups. When we multiply, the number of things in the group increases. The twofactors and the product are parts of a multiplication problem.

Given:

n=0.9

Now, there is one number behind decimal point.

So, we have to multiply it by 10 to convert it into fraction from decimal.

Thus,

10n = 0.9*10

10n = 9

n = 9/10

Hence, the number must be multiplied is 10
