It takes 8 hours to clean 12 houses so that’s 8/12 to find how many hours it take to clean one house, 8/12 is equal 2/3 . So it takes 2/3 of an hour to clean one house. 2/3 times 12 equals 8. So you want to find how many houses you can clean in 12 hours. The equation is 12= 2/3x , x=18. The answer is 18 houses. Check the work cus I sure didn’t lol, hope this helps
Answer: 2 books.
Step-by-step explanation:
The rate of doing a given activity in a given amount of time can be calculated as:
Rate = (how much you do)/(time that it takes)
In this case, we know that:
Marcos reads (3 + 1/2) books in (1 + 3/4) weeks.
then the rate is calculated as:
R = (3 + 1/2) books/(1 + 3/4) weeks
= (3 + 1/2)/(1 + 3/4) books per week.
= (6/2 + 1/2)/(4/4 + 3/4) books per week
= (7/2)/(7/4) books per week
= 4/2 books per week
= 2 books per week
This means that marcos can read 2 books in one week.
The first number is x
the second number is 2x-4
combine both numbers = 80
x+2x-4=80
3x-4=80
3x=84
x=28
one number is 28 and the other is 52.
To determine the break even sales, equate the total revenue to total cost. Allow x to represent the number of panels GlassWorks should sell, the break even analysis becomes,
$135x = $108,000 + $78x
Solving for x gives an answer of x = 1894.73 which is approximately 1895. Thus, GlassWorks should sell 1895 panels.
Answer: 8 hours
Step-by-step explanation:
<u>Given information</u>
Admission fee = $7.00
Hour rent fee = $1.50
Number of hours = h
Total fee = $19
<u>Set equation according to the given information</u>
Total fee = admission fee + (hours) × (hour rend fee)
<u>Substitute values into the equation</u>
19 = 7 + 1.5h
<u>Subtract 7 on both sides</u>
19 - 7 = 7 + 1.5h - 7
12 = 1.5h
<u>Divide 1.5 on both sides</u>
12 / 1.5 = 1.5h / 1.5
Hope this helps!! :)
