Answer: D. n + q = 20
5n + 25q = 300
Step-by-step explanation:
Let n represent the number of nickels that you have.
Let q represent the number of quarters that you have.
Suppose you have 20 coins. It means that
n + q = 20
The total value of the coins is $3. The value of a quarter is $0.25 and the value if a nickel is $0.05. Therefore, the equation would be
0.05n + 0.25q = 3
Multiplying both sides of the equation by 100, it becomes
5n + 25q = 300
The correct option is
D. n + q = 20
5n + 25q = 300
All you need to do for angles like GBH is work out the angle at point B. With questions like this, work out the angle at the letter in the middle.

Answer:

Step-by-step explanation:
We are given the integral of:

First, we can use a property to separate a constant out of integrand:

Next, expand the expression (integrand):

Since
then it can be simplified to:

Recall the formula:

For
, we need to convert to another identity since the integrand does not have a default or specific integration formula. We know that:

We can solve for
which is:

Therefore, we can write new integral as:

Evaluate each integral, applying the integration formula:

Then add all these boxed integrated together then we'll get:

Expand 4 in the expression:

Therefore, the answer is:

4/7
