Step-by-step explanation:
let number of green balls= x
let number of orange balls=x+4
x+x+4=38
2x=38-4
2x=34
x=17
number of green balls=17
number of orange balls=21
Answer:
y=1.3x-3
or
y=4/3x-3
Step-by-step explanation:
1.3 is the slope (the change in between points)
-3 is the y intercept (the point on the y-axis)
It took Andre and Lin 1.5 hours for them to meet.
Speed is the ratio of distance travelled to total time taken. Speed is given by:
Speed = distance/time
Let d₁ represent the distance covered by Andre at time t and d₂ represent the distance covered by Lin at time t.
Hence:
5 = d₁/t
d₁ = 5t
3 = d₂/t
d₂ = 3t
Andre and Lin are 12 miles apart, hence:
d₁ + d₂ = 12
5t + 3t = 12
8t = 12
t = 1.5 hours
It took Andre and Lin 1.5 hours for them to meet.
