Ali’s earnings vary directly with the number of hours he works. Suppose that he worked 10 hours yesterday and earned $130. how much will he earn today is he works 13 hours?

He earns $169 after 13 hours

Step-by-step explanation:

To solve this we need to find out how much he earns per hour.

This can be identified using simply division.

130/10=13

He earns $13 per hour.

Now we multiply 13*13=169

He earns $169 after 13 hours

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
