Answer:

3s - 10 = 65

Step-by-step explanation:

s = the shirt price

Since Jason bought 3 shirts, we need to multiply the 3 shirts by its value which would be 3s. He has a coupon for $10 off, so we need to subtract 3s by 10. Since he spent $65 we need to set the whole equation equal to 65 and out final answer would be 3s - 10 = 65.

1/3k+80=1/2k+120 what does k equal?

LenaWriter [7]

Answer:

k = -1/240

Step-by-step explanation:

to evaluate the value of k in the expression 1/3k+80=1/2k+120

we have

1/3k+80=1/2k+120

collect the like terms for easy evaluation

1/3k - 1/2k = 120 -80

1/3k - 1/2k = 40

find the lcm

2 - 3/6k = 40

-1/ 6k = 40

cross multiply

6k x 40 = -1

240k = -1

divide both sides by 240

240k/240 = -1/ 240

k = -1/240

therefore the value of k in the expression 1/3k+80=1/2k+120 is equals to -1/240
