<h3>
Answer: 2.5 hours</h3>
This is equivalent to equivalent to 2 hours, 30 minutes.
======================================================
Work Shown:
1/3 of the house = 50 minutes
3*(1/3 of the house) = 3*(50 minutes)
3/3 of the house = 150 minutes
1 house = 150 minutes
-----------
Sam will need 150 minutes to clean the whole house
Divide this over 60 to convert to hours
150 minutes = (150/60) hours
150 minutes = 2.5 hours which is the final answer
-----------
Or you could say the following
150 minutes = 120 min + 30 min
150 minutes = (120/60) hr + 30 min
150 minutes = 2 hr + 30 min
This shows that 2.5 hours is equivalent to 2 hours, 30 minutes.
Step-by-step explanation:
The domain is all the x values that are included in a function.
Here the x values are from -11 to 9.
So the domain is [-11,9]
Answer is x = 68 and y = 55
Let’s assume the two numbers are x and y
X + y = 123 — (1)
X + 5y = 343 — (2)
Write (1) in terms of x
X = 123 - y — (3)
Use in (2)
123 - y + 5y = 343
Rearrange to have only y terms on the right.
-y +5y = 343 - 123
4y = 220
y = 220/4 = 55
Found y = 55
Use y = 55 in (3)
X = 123 - 55 = 68
Found x = 68
