Kevin is 39 years old and Daniel is 3 years old. How many years will it take until Kevin is only 4 times as old as Daniel?

K=39 and d=3

(k+y)/(d+y)=4 using k and d given...

(39+y)/(3+y)=4 multiplying both sides by (3+y)

39+y=12+4y subtracting 4y from both sides

39-3y=12 subtracting 39 from both sides

-3y=-27 dividing both sides by -3

y=9

So in nine years Kevin will be four times as old as Daniel.

check...

(39+9)/(3+9)=4

48/12=4

4=4

The howler monkeys at a zoo are fed a diet that contains 3.35 kcal/gram. Write a function g(x) that gives the mass of food in gr

Dvinal [7]

The amount of energy that the given amount of food contains is the product of the given content per grams and the amount of food in grams.

For this item, we assume that g(x) is the total energy that the howler monkey needs to obtain and x is the amount of food in grams. From the presented concept in the first paragraph,

amount of energy = (3.35 kcal/gram) x (amount of food)
g(x) = 3.35x
