Kevin earns $12.00 for every 5 story problems he writes. How much would Kevin get for writing 12 problems?

$28.80

Step-by-step explanation:

We can start by finding the unit rate. How much money does Kevin earn from writing 1 story problem?

We can find how much Kevin earns from writing 1 story by dividing 12 by 5.

12 ÷ 5 = 2.4.

Therefore, Kevin earns $2.40 for every story he writes.

Now we have to find how much Kevin earns from writing 12 story problems. If Kevin earns $2.40 for every story he writes, then we should mutliply that by 12 to find how much money Kevin earns for writing 12 problems.

2.40 x 12 = 28.8.

In conclusion, Kevin earns $28.80 dollars for writing 12 problems.

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.

i believe that the answer is

b. y-1=-2(x-4)

hope this !
