6.7w - (-3)w = -5
42w + 3w = -5
45w = -5
w = -5/45
w = -1/9
Hope this helps!
Answer: 39 7/12km
Step-by-step explanation:
From the question, we are informed that Andrew jogs 25 5/6 kilometers a week while Yen jogs 13 3/4 kilometers a week.
The total distance they jog in a week will be the addition of the distance that each person jogged. This will be:
= 25 5/6 + 13 3/4
= 25 10/12 + 13 9/12
= 38 19/12
= 38 + 1 7/12
= 39 7/12
The total Distance covered by both of them is 39 7/12 kilometers
Given: "<span>B(t)=4*e^0.8t, How many hours will it take for the population to grow to 400?" Set B(t) = 400. Then:
400=4*e^(0.8t), or
100 = e^(0.8t)
Take the natural log of both sides, obtaining
ln 100
ln 100 = 0.8t. Then t = ----------- = 5.76 hours.
0.8</span>
