Step-by-step explanation:
-5(3z - 2) = -5*3z - (-5)*2
= -15z + 10
The total number of marbles is 30+20+50= 100, so. Since there are 20 red marbles and 50 blue marbles. There are 30+50=80. 80/100=4/5= 80%
6) B&R. They form a right angle at intersection
7) G&R. Line G has a slope of -1/4 which is the negative reciprocal of line R’s slope of 4
