The number in the question that gives 28 after the operations is; <em><u>3</u></em>

We are told that the product of seven and the sum of a number and 1 is 28.

Let the number be x. Thus;

7(x + 1) = 28

Use division property of equality to divide both sides by 7.

7(x + 1)/7 = 28/7

(x + 1) = 4

Use subtraction property of equality to subtract 1 from both sides to get;

x + 1 - 1 = 4 - 1

x = 3

Therefore, in conclusion the number is 3.

Answer:

It is a function

Step-by-step explanation:

This isn't really a step by step explanation but I'm going to explain this simply. An output can have as many inputs possible but an input can only have ONE OUTPUT(just putting emphasis on this one output, I'm not yelling). Example, the input "2" can be equal to the output of "4" depending on the equation the fuction, however, the input of "2" CAN NOT be equal to the outputs of "4" and "6" because as my Algebra teacher explained it "for every input, there is exactly one output". I hope this helps and I hope I didn't lose you in my explaination.

... 43 hours × $9.00 = $387

... - 6.2% × $387 = $23.99

... - 1.45% × $387 = $5.61

... - $15.00

... - 5% × $387 = $19.35

... - 10% × ($387 -19.35) = $36.77

Solve x:<br> 4 - 4x = 40<br> --Please Help! This is homework due in for Monday! Xx
salantis [7]

Hello!

<u><em>Answer: x=-9 *The answer must have negative sign*</em></u>

Explanation:

First you had to do is subtract by 4 from both sides of an equation.

4-4x-4=40-4

Then, simplify.

-4x=36

Divide by -4 both sides of an equation.

\frac{-4x}{-4}= \frac{36}{-4}

Finally simplify.

36/4=9

It change positive to negative sign.

x=-9

Hope this helps!

Thanks!

Have a great day!
