4.

5.

6. t+97

Step-by-step explanation:

4. If 7 students out of 12 are in fifth grade, the rest of the 12 students (12-7) are in 6th grade.

6. If the bill (t) is 41, than her electric bill is going to be t+97 because the electric bill is $97 more.  Then you plug in 41 for t, 41+97= 138

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
