Olivia wants to cut off 3 3/4inches from a piece of string. She has already cut off 2 9/16 inches from the piece of string. How much more string should she cut off?

1 3/16 inches

Step-by-step explanation:

3 3/4 = (3+12) / 4

2 9/16 = ( 9+ 32) / 16

15 / 4 - 41/ 16 make the denominators equal

15 × 4 / 4×4 - 41/ 16

= 60/16 - 41/16

= 19/16 convert it to Fractional number

= 16 + 3 / 16 = 1 3/16

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
