Answer:
5
Step-by-step explanation:
The left side simplifies to ...
2x +16
The right side simplifies to ...
2x +21 -__
The x-terms are already equal. To make the constant terms equal, we want ...
16 = 21 -__
The blank must be filled with the value 21-16 = 5 to make the statement true.
5 goes in the blank.
Approximately 7.4 inches. You can use the Pythagorean theorem to get you diagonal or hypotenuse.
It is false that there is a <span>negative correlation between the number of years in college and earnings.</span>
Distribute 7 to both n and 1
7(n + 1) = 7n + 7
5n + 7 = 7n + 7 - 2n
Combine like terms
5n + 7 = 7n - 2n + 7
5n + 7 = 5n + 7
If you want to solve for n, subtract 7 from both sides
5n + 7 (-7) = 5n + 7 (-7)
5n = 5n
then divide 5 from both sides
5n/5 = 5n/5
n = n
Effectively, this equation is <em>unsolvable</em>

The answer is 350.
<em>
m= minutes</em>
Plan 1: 9+0.13<em>m</em>
Plan 2: 23+0.09<em>m</em>
9+0.13<em>m</em> = 23+0.09<em>m</em>
-9 -9
0.13<em>m</em> = 14+0.09<em>m</em>
-0.09<em>m</em> -0.09<em>m</em>
0.04<em>m</em>= 14
14÷0.04= 350
<em>m</em>= 350
