3. After 10 minutes, the height of the water is 4 inches
Answer:
1) P(20) = 0
2) P(0) = 0
3) P(10) = 4
4) P(4) = 10
Step-by-step explanation:
We are told that the function P(t) denotes the height of the water in the bath tub.
At P(0) = 0, it means that after 0 minutes, there is no water in the bath tub.
1) If after 20 minutes, the bathtub is empty, then we can depict the function as; P(20) = 0
2) The bath tub starts out with no water. It means at 0 minutes, there was no water in the tub. Thus;
P(0) = 0
3) If after 10 minutes, the height of the water is to be 4 inches, then;
P(10) = 4
4) If the height is 10 inches after 4 minutes, then;
P(4) = 10
Answer : p=2
2p-2-5x=-2(7-2x)
First, work on the parentheses. So the -2 on the outside as to be multiplied by the 7 , which gets -14 . Then you multiply the -2 by the 2x, which is 4x.
It will go from -2(7-2x) to -14+4x
But if the -14+4x looks too confusing, you can just switch them around to look “normal”. So it would be 4x-14 .
Now that we’re finished with one side of the problem, we’ll go to the other side.
On the left side , there are two variables, or letters. Because they are the same letter (p) all you have to do is add them together.
3p
-5p
+—-
-2p
And then just carry the -2 that was originally there , so it’s -2p-2
Now the equation is
-2p-2 = 4p-14
So we’re going to add 2p to both sides.
The -2p on the left cancels out, and the 4p on the right side becomes 6p
-2 = 6p-14
Next, you are going to want to isolate the variable. (Leave the letter by itself) so you add 14 to the -14 , so it can cancel out. (AND DO THE SAME ON THE OTHER SIDE)
So, you add 14 to the -2 on the left of the equation. Which comes out to 12.
12 = 6p
Lastly, divide the 6p , so you can get the letter on it’s own. And do the same on the other side.
12 divided by 6 is 2
2 = p
OR
p = 2
The expression that shows the number of boxes ordered is 8p.
<h3>What is an expression?</h3>
Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both. Addition, subtraction, multiplication, and division are all possible mathematical operations.
Since the school custodian ordered p rolls of paper towels and the paper towels are sold in boxes of eight.
The expression will be:
= Number of rolls × 8
= p × 8
= 8p
The expression is 8p.
