Answer:

x - 7

Step-by-step explanation:

Let's let x = 4 and see which one would be different

x - 7 = 4 - 7 = -3

7 + (-x) = 7 + -4 = 3

-x + 7 = -4 + 7 = 3

7 - x = 7 - 4 =3

As you can see, the top answer would be negative while all the rest are positive. This is because, in that case, the negative sign was attached to the 7 instead of the x.

# [4-5{1-(4-3+1)}] of 100% equals <br><br> a) 50%<br> b)-1%<br> c)zero<br> d)100%
Nikitich [7]

<u>Answer:</u>

To solve this, we need to first evaluate the given expression. We can do that by simplifying the contents of each bracket, starting with the innermost one:

[4-5{1-(4-3+1)}]

⇒ [4 - 5{1 - (2)}]

⇒ [4 - 5{-1}]

⇒ 4 - (-5)

⇒ 4 + 5

⇒ 9

Now we can calculate what 9 out of 100 is:

9 of 100  =  \frac{9}{100}

              ⇒  9%

A copy center charges an initial cost per each new job, plus fixed amount for each copied page. John copied 425 pages and paid $
jok3333 [9.3K]

Answer:

Initial cost for a job = $2

Step-by-step explanation:

Let initial cost be $x.

Fixed amount for each copied page  = $y

John:

Fixed amount for 425 pages = 425*y = 425 y

x + 425y = 10.50  ---------------(i)

Peter:

Fixed amount for 300 pages = 300 * y =300y

x + 300y = 8   ---------------------(ii)

Multiply (ii) by (-1) and add the both equation. Thus x will be eliminated.

(i)            x + 425y  = 10.50

(ii)*(-1)     <u>-x - 300 y = - 8</u>

                    125y = 2.50

                          y = 2.50/125

y = $ 0.02      

Plug in y value in equation (i)

x + 425*0.02 = 10.50

x + 8.50 = 10.50

x = 10.50 - 8.50

x = $2
