Luna mixes 3/4 cup of orange juice with 3/8 cup of cranberry juice. She gives 5/8 cup of the juice to mags. How much is left in lunas glass

1/2

Step-by-step explanation:

3/4+3/8=9/8

9/8-5/8=1/2

1/2 is left in Luna's glass

Step-by-step explanation:

3/4 is the same as 6/8

So 6/8 + 3/8 = 9/8

9/8 - 5/8 = 4/8.

4/8 can be simplified to 2/4, which can be simplified to 1/2

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
