Answer: x= 0.18779342
Step-by-step explanation:
Answer:
y=3x
idk
Step-by-step explanation:
I know this is only half an answer, but for a they have the same slope and it's proportional so it has no b value.
34. 65 = 3/4c - 7....add 7 to both sides
65 + 7 = 3/4c...simplify
72 = 3/4c...multiply both sides by 4/3, eliminating the 3/4 on the left
72 * 4/3 = c
288/3 = c
96 = c
36. -5/2 = 3/4z + 1/2 ...subtract 1/2 from both sides
-5/2 - 1/2 = 3/4z .... simplify
-6/2 = 3/4z ....reduce
-3 = 3/4z....multiply by 4/3. eliminating the 3/4 on the left
-3 * 4/3 = z
-12/3 = z
-4 = z
70
make 30 minutes into an hour then divide 140 by 2
140/2=70
70x1=70
