Answer:
x = 36
Step-by-step explanation:
3x+2x=180
5x=180
x=36
Given the function f(x);
Evaluating the function f(x+h);
So;
Evaluating the second function;
simplifying further;
Therefore, we have;
The distributive property: a(b + c) = ab + ac
8 × 19 = 8 × (20 - 1) = 8 × 20 - 8 × 1 = 160 - 8 = 152
Answer:8.4
Step-by-step explanation:
Ten percent of 14 is 1.4 so add 1.4 4 times or multiple 1.4 by 4 and you get 5.6, then subtract 14 by 5.6 and you get 8.4

Answer: n = 9 is a solution. </h3>
========================================================
Explanation:
Let's replace n with 9 to see if we get a true inequality or not.
2n > 16
2*9 > 16
18 > 16
We get a true statement since 18 is indeed larger than 16. Therefore, n = 9 is a solution.

Here's another way to tackle the problem:
We can isolate n as if solving an equation. Divide both sides by 2 to do this. The inequality sign does not flip (it only does so if you divide both sides by a negative number).
So we get...
2n > 16
2n/2 > 16/2
n > 8
The solution set is any number larger than 8. Since n = 9 fits the description, that's one of the infinitely many solutions.
