Distribute -7 because of math
-21-56x+5x≤1-62x
add like terms because you aint chaingin nothing
-21-51x≤1-62x
add 62x to both sides (addition property of equality, where a=a and b=b, a+b=a+b) and also (addative inverse, a+(-a)=0) that turns the -62x to 0
-21+11x≤1
add 21 to both sides (additiona proerty of equality and addativeinverse)
11x≤22
divide both sides by 11 (division property of equality, if a=a and b=b, then a/b=a/b)
x≤2

A campsite charges $12 per day for the site rental and $8 for parking . The total campsite charge C (in dollars) is given by C=1
Vsevolod [243]

We are given equation of total campsite charge

C=12d+8

where

C is total campsite charge C (in dollars)

d is the number of days that the site is rented

so, here we will have

C is y-axis or dependent variable

d is x-axis or independent variable

we can find any two points and then we locate it

after that we can join them to get our graph

At d=0:

C=12\times 0+8

C=8

so, our point is (0,8)

At C=0:

0=12d+8

-8=12d

d=\frac{-2}{3}

so, our point is (\frac{-2}{3},0)

now, we can locate these points and then join it

yanalaym [24]

Answer:

x=5

Step-by-step explanation:

10 +3x = 5x

Subtract 3x from each side

10+3x-3x= 5x-3x

10 =2x

Divide each side by 2

10/2 = 2x/2

5 =x
