Jamie's chemistry textbook weighs 7/10 of a pound and his geometry textbook weighs 3/5 of a pound. How much more does the chemistry textbook weigh than the geometry textbook?

Below.

Step-by-step explanation:

So the note book weighs 7/10 and the Text book weighs 3/5 We have to find the common Number so 10. Anyway, so To get ten 5x2 = 10 do the same thing to the top = 6/10 7/10 is bigger than 6/10

By

1/10.

here is your mark brainliest

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
