Answer:
Step-by-step explanation:
m = (4-1) / (9-5)
m = 3/4
35%.
42/120 = 0.35.
0.35 X 100 = 35. That tells us 42 is 35% of 120.
Answer: a = -5
Step-by-step explanation:
First, open up the brackets, and solve it
-12a -42 = -22 -8a. (-6 x 2a, and -6 x 7)
bring the -8a to the left side, so that all the a’s are together
-12a -42 + 8a = -22 (add -42 on both sides like we did with -8a)
-12a + 8a = -22 + 42
solve
-4a = 20
divide -4 on both sides
a = -5
