Answer:
Let B have x days work:
A + B = 3 days
1/4 + 1/x = 1/3
1/3 - 1/4 = 1/x
1/12 = 1/x
x = 1 / (1/12)
x = 12
B takes 12 days

Answer:
3.2*10^8>1.2*10^8>7*10^5>5*10^3
Step-by-step explanation:
5*10^3 = 5000
3.2*10^8=320000000
1.2*10^8=120000000
7*10^5=700000
320000000>120000000>700000>5000
therefor
3.2*10^8>1.2*10^8>7*10^5>5*10^3
Answer:
y=4x-2
Step-by-step explanation:
y=mx+b
where m=slope and b=y-intercept.
y-6=4(x-2)
y-6=4x-8
y=4x-8+6
y=4x-2
