QUESTION
If x = 2n + 1, what is the value of x when n = 10?
EXPLANATION
To find the value of x when n is equal to 20, all you have to do is substitute n with 10 in the equation you are given.
<u>Substitute:
</u>
Your new equation is
Now you need to multiply the 2 and 10 to take out the parentheses.
Your new equation is
<u>Lastly, you have to add 20 and 1
</u>
That means your answer is x = 21
The product will have the negative sign
You have to insert -3 and -3 for x and y, so
-6(-3)+4(-3)=6
18-12=6
Yes, it is a solution.
Answer:
78 rounds to 80, so find 10% of 80 and double it. 10% of 80 is 8. So, 20% of 80 is 16. Then, 22% of 78 is a little more than 16.
78 rounds to 80, and 22% is a little less than 25%. 25% (or one-fourth) of 80 is 20. So, 22% of 78 is a little less than 20.
