The amount lin's sister earns at her part-time job is proportional to the number of hours she works. she earns $9.60 per hour. write an equation in the form of y=kx to describe this situation, where x represents the hours she works and y represents the dollars she earns

Step-by-step explanation:

If represents the hours she works and represents the dollars she earns, and she earns at a ratio of $9.60 per hour, then the expression would be

Because, the ratio must multiply hours to give the total amount of money she earns.

For example, if Lin's sister works 10 hours, then she earns

Basically, each hour is gonna be multiplied by the ratio of change, which is $9.60.

Therefore, the answer is

4 packs of water and 7 packs of candy bars

step-by-step explanation:

35x4=140

140/20=7

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

−3
