Please use "write" here, not "right." "write" is "right" here, if you get my drift.
"right" is wrong in this context. ;)
Example: Most of us would see immediately that 5 is a prime factor of 50.
Write 50 as 5 * 10.
10 is not prime; it can be factored into 5 and 2.
Thus, 50 written as the product of its prime factors is 5 * 5 * 2 (answer)
Answer:
n = 1, 4
Step-by-step explanation:
Step 1: Write equation
n² - 5n + 4 = 0
Step 2: Solve for <em>n</em>
<u>Factor:</u> (n - 4)(n - 1) = 0
<u>Find roots:</u> n = 1, 4
Step 3: Check
<em>Plug in n to verify if it's a solution.</em>
1² - 5(1) + 4 = 0
1 - 5 + 4 = 0
-4 + 4 = 0
0 = 0
4² - 5(4) + 4 = 0
16 - 20 + 4 = 0
-4 + 4 = 0
0 = 0
To find the box answer, you can divide y by x:
You can check every pair, bit I'm going to show you the first 2 as an example:
So 3/2 is the answer!
Answer: 80 minutes
Step-by-step explanation:
Hi, to answer this question we have to write an equation for each tank:
An empty 1200 gallon tank is filled with water at a rate of 6 gallons of water per minute.
So, the amount of water of the tank is equal to the filling rate, 6 liters per minute (6m)
- Tank 1 =0 (empty )+ 6m =6m
The second 1200 gallon tank full of water is being drained at a rate of 9 gallons per minute.
So, the amount of water in the tank is equal to the amount of water already in the tank (1200 g), minus the draining rate (9m)
Since both tanks will have the same amount of water:
6m = 1200-9m
Solving for m (minutes):
6m+9m= 1200
15m = 1200
m= 1200/15
m= 80 minutes
Feel free to ask for more if needed or if you did not understand something.
