3x + x - 13 + 4 - 6x =12

Combine like terms....

- 2x - 9 =12

Add 9 to both sides....

-2x = 21

Divide both sides by -2 to get x by its self....

x = -21/2

Jonathon and Raymond earn a base salary plus commission. Jonathon earns $1500 plus 10% of his sales each month. Raymond earns $1

joja [24]

Answer:

The Jonathon and Raymond need to sell 6000 sales to earn the same amount each month.

Step-by-step explanation:

Given data

Let no. of sales = x

Jonathon earning = $ 1500 + $\frac{10}{100} x$

Raymond earning = $ 1200 + $\frac{15}{100} x$

Given that the earnings of Jonathon & Raymond are same.

1500 + $\frac{10}{100} x$ = 1200 + $\frac{15}{100} x$

300 = $\frac{5}{100} x$

x = 6000 sales

Therefore the Jonathon and Raymond need to sell 6000 sales to earn the same amount each month.

How do i solve this rational expression r-4/5r=1/5r+1

NNADVOKAT [17]

r - 4/5r = 1/5r + 1

Subtract 1/5r from each side: r - 4/5r - 1/5r = 1

Combine all the 'r' terms on the left side:

 r - 5/5r = 1

 r - r = 1

 0 = 1

There is no value of 'r' that can make ' 0 = 1 ' a true statement.
So the equation has no solution.
