Hello, there!
<span>Ten times a number is sixteen more than twice the number. Find the number.
Answer: 2
-----------------------------------------------------------------------------------------------------
Explanation:
</span>
First, let's write the equation.
Ten times a number -- 10x
16 more -- 10x - 16
Twice the number -- 2x
10x - 16 = 2x or 10x = 2x + 16
Let's use the first one: 10x - 16 = 2x
First, let's isolate the x to one side.
10x - 16 = 2x
-10x -10x
-16 = -8x
Now, let's multiply each side by -1 to make them positive
-16 = -8x
*-1 *-1
16 = 8x
Finally, let's divide each side by 8
16 = 8x

8 8
Our answer is 2 = x
This means that the number is 2.
I hope I helped!

Answer:
Surface area means all of the outside areas, kind of like when you wrap a present.
Step-by-step explanation:
1st draw the box and find the area of the top and the bottom of the figure
10 x 3 = 30 for the top and 30 for the bottom, so 60 for both.
2nd find the area of two opposite sides:
10x 4.5 = 45 for one side and 45 for the other side, which is 90 for both
3rd find the area of the last two opposite sides:
3 x 4.5 = 13.5 for one side and 13.5 for the other side, so 27 for both.
4th: now add all those sides 60 + 90 + 27 = 177 inches squared.
if you mean -2 and 3. than the answer would be f(x +2)
