Jen's favorite subject: Science.

Grade: 8th

Step-by-step explanation:

Based on the information given in the question we can form a table as follows:

It was given that:

     This means that the student in 4th grade likes Art.

      Also it is given that:

     Sue likes art best and is not in 8th grade.

     This means that Sue is in 4th grade and likes Art.

      Hence Betty likes math and is in sixth grade.

           and Jen likes science and is in 8th grade.

Hence,

Jen's favorite subject: Science.

Grade: 8th

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)(

1

4

)=(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
