Hello, there!
<span>Ten times a number is sixteen more than twice the number. Find the number.
Answer: 2

Explanation:

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:
Yes, two positive real numbers will always equal a positive number. If two numbers have the same sign, whether positive or negative, the product will always be positive.
Answer:
Step-by-step explanation:
The position equation is given as
and we are looking for the times when the position of the ball is 9 feet. That means that we simply plug in a 9 for s(t) and factor to solve for t:
and
and this is what we factor to find t:
t = .42 sec and then again on its way back down at t = .89 sec
I think the equation for this would be 9+1.35x
then i think you would have to round it after because you cant really have a third of someone.
Answer:
16 serving.
