H(n) = n + 3 g(n) = 3n Find (h + g)(n)

Mathematics
1 answer:

Answer:

(h+g)(n)=4n+3

Step-by-step explanation:

So we have the two functions:

h(n)=n+3\text{ and } g(n)=3n

And we want to find (h+g)(n).

This is the same as: h(n)+g(n). So, substitute:

h(n)+g(n)\\=(n+3)+(3n)

Combine like terms:

=4n+3

So:

(h+g)(n)=4n+3

And we're done!

Kenzie finds purple, blue, and silver space rocks while exploring, 2/3 of the rocks are purple and 3/4 of the remainder are blue
Nadya [2.5K]

Answer:

There were 36 space rocks in total.

Step-by-step explanation:

First, you need to find what fraction of the original rocks are silver.

If 2/3 are purple, then 1/3 of them are not.

If 3/4 of the remaining 1/3 are blue, then 3/4 x 1/3 = 3/12 rocks are blue.

2/3 of the rock are purple, 3/12 of them are blue, and the remaining is silver.

So, you need to do 2/3 - 3/12, then find common denominators so, 8/12 - 3/12 which = 1/12.

This means 1/12 of the rocks are silver. If there are silver rocks, you need to find a suitable equation that needs to be solved.

So:

1/12r = 3

r = 36 silver rocks

There were 36 space rocks in total.

hope this helps :)
