What is the solution for the equation -3d/d^2-2d-8 + 3/d-4 = -2/d+2

olasank [31]

-3d/(d^2-2d-8) + 3/(d-4) = -2/(d+2)

factor

-3d/(d-4) (d+2) +3/(d-4) = -2/(d+2)

multiply by (d-4)(d+2) on each side

(d-4)(d+2)[-3d/(d-4) (d+2) +3/(d-4)] = (-2/(d+2))*(d-4)(d+2)

distribute

-3d +3(d+2) = -2(d-4)

distribute

-3d +3d+6 = -2d+8

combine like terms

6 = -2d+8

subtract 8 to each side

-2 = -2d

divide by -2

1 =d

A party store uses 20% of a tank of helium a day and fills 80 balloons. Each balloon takes 0.5 cubic feet of helium to fill. How

Vesnalui [34]

First, multiply the number of feet it takes for one balloon by the number of balloons filled daily.
0.5 * 80 = 40

So, 40 cubic feet is 20% of one tank. Now, unless you remember how to find what 40 is 20% of, simply play around with some numbers on your calculator until you find that 200 * 0.20 = 40. I would love to explain how to find that part with an actual formula, but I don't remember how. :/ Hope this helped.

A 12,000-lb killer whale might eat as much as 14,000 lb of fish per month (assume a 30-day month). If the average weight of a ce

brilliants [131]

Answer:

2196 fish

Step-by-step explanation:

Weight of fish that the killer whale might eat in a month (30 days) = 14,000 lb

Weight of the fish that killer whale might eat in a day = $\frac{14000}{30} = \frac{1400}{3}$ lb.

Average weight of the fish that killer whale eats = 3.4 oz

Since,

1 pound(lb) = 16 ounces(oz)

So,

Weight of the fish that killer whale might eat in a day in ounces(oz) = $\frac{1400}{3} \times 16=\frac{22400}{3}$ oz

Since, a certain fish weighs 3.4 oz, in order to find the number of fish that killer whale must eat, we must divide the total weight in ounces by 3.4 ounces.

So, the number of fish that killer whale would eat = $\frac{22400}{3} \div 3.4 = 2196$ fish

Thus, the killer whale needs to eat 2196 fish.
