Sure b and c would probs be right
r/v + a = 5
subtract a from both sides
r/v = 5-a
multiply by v on both sides
r = v*(5-a)
Answer:
2.67 days
Step-by-step explanation:
75/4=18.75
18.75/50=2.67
0.45(x + 1.6) + 5x = 18
0.45x + 0.72 + 5x = 18
5.45x = 18 - 0.72 = 17.28
x = 17.28 / 5.45
x = 3.17 answer
X is less than or equal to 6
