PART 1:
5(2x-4)=30
Multiply both 2x and -4 by 5

10x-20=30
Then add 20 to cancel it out, but once u do something to that side u must do it to the other side. So add 20 to 30 which is 50.

10x=50

10x/10= 50/10
Divide both side by 10

X=5



PART 2:
5x + 3 - x + 2 = 41

4x + 5 = 41
Combine the like terms

4x=36
Then subtract 5 from both sides to cancel to get 4x by itself

4x/4=36/4
Then divide both sides by 4

X=9

Answer:

see below

Step-by-step explanation:

Part 1: 5(2x - 4) = 30.

Distribute

10x -20 = 30

Add 20 to each side

10x-20+20 =30+20

10x = 50

Divide by 10

10x/10 = 50/10

x =5

Part 2: 5x + 3 - x + 2 = 41

Combine like terms

4x +5 = 41

Subtract 5 from each side

4x+5-5 = 41-5

4x = 36

Divide by 4

4x/4 = 36/4

x = 9

Ervin sells vintage cars. Every three months, he manages to sell 13 cars. Assuming he sells cars at a constant rate, what is the
Vladimir [108]
Ervin sells 13 cars per 3 months so 13/3=4.3 cars per month. 

this means that 

___month___     ___cars sold___

          1                         4.3
          2                     2*4.3
          3                     3*4.3
          :                           :
          n                     n*4.3

the linear function representing the cars sold per month is f(n)=4.3*n

(Practically, this means that the expected number of cars sold after n months is a whole number close to 4.3*n.)

Answer:

the slope is 4.3 (13/3)

If I make 11.50 an hour working full time (40 hours a week) how much money do i make a year after deducting 60 dollars of taxes
Kazeer [188]
Given:
hourly rate = 11.50
hours worked in a week = 40 hours
taxes per moth = 60

Every month may be 4 weeks or 5 weeks but we know that 1 year has 52.1429 weeks.

Let us compute for the whole year:

Earnings:
11.50 /1 hour * 40 hours/1week * 52.1429 weeks/1year  
= 11.50 * 40 *  52.1429/year
= 23,985.734 per year

Taxes:
60 / per month * 12 months / 1 year
= 60 * 12/year
= 720 per year

Net earning per year
23,985.734 - 720 = 23,264.734 

Net earning per month
23,264.734 ÷ 12 months = 1,938.81 

You will earn 23,264.73 annually from a monthly earning of 1,938.81
