Jake went to the park. he spent 30 minutes walking on a trail. the rest of the time he spent relaxing in the park field. he spent a total of 86 minutes at the park. how many minutes did he spend relaxing in the park field? use the variable r to represent the number of minutes jake spend relaxing.

which equation represents this situation and its solution?

a. 86r = 30; r = 56

b. r + 86 = 30; r = 116

c. 30r = 86; r = 56

d. r + 30 =86; r = 56

plz in the next 15 mins? ? pl thx about 8 points

D. r + 30 =86; r = 56

Step-by-step explanation:

I took the test online in K12 and when I reviewed it said that D is the correct answer.

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

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.
