Plz help I need this for my grade report cards are coming out

1.5

1st box: 0.75

2nd box: 1.5

3rd box: 3

4th box: 28

Step-by-step explanation:

First I got the 4th box. I found out 3.5x2=7, and 7x2=14. So I know the pattern is multiply by 2.

Then I got the 3rd box. I used a proportion. (14x6)/28= 3

Then the 2nd box. I did (3x7)/14=1.5

Lastly, I did the 1st box. (1.5x3.5)/7= 0.75

I hope that helped :)

Equation: 7t= 80+9t
Cancel out 9t and bring it to the other side: 7t-9t=80 
                                                                     -2t=80
Divided -2 from t to isolate t: t= 80/-2
                                              t= -40
