72/3=24
24/12=2(2 meters a person a day)
2*15=30
15 people can build about 30 meters of fence a day.
Mom drove for 11 hours.
Dad drove for 3 hours.
<u>Step-by-step explanation</u>:
- Total distance = 895 miles
- Mom drove a speed of 65 mph
- Dad drove a speed of 60 mph
Let 'x' be the number of hours drove by mom.
Let 'y' be the number of hours drove by dad.
x + y = 14 ---------------(1)
65x + 60y = 895 ---------(2)
Multiply eq(1) by 60 and subtract eq(2) from (1),
60x + 60y = 840
-(<u>65x + 60y = 895</u>)
<u> -5x = -55 </u>
x = 55/5
x = 11
∴ Mom drove for 11 hours.
Substitute x=11 in eq(1)
11+y = 14
y = 3
∴ Dad drove for 3 hours.
x = -2, x = 5
=> f(x) = a(x+2)(x-5), a ∈ R
7 gallons for minute because 49 divided by 7 (which is the mins) would be 7. Leading to the answer of ) gallons per minute
Answer:
Step-by-step explanation:
Any negative (when there is only one of them) will be the least. negatives are smaller than positives.
A fraction is less than a whole number. So far what you have is
___ ___ 3/15 , - 24/30
So now which is bigger? 11 or 11.5
Which would you rather have? 11 dollars or 11 dollars and 50 cents. 11.5>11
The correct order is 11.5 11 3/15 - 24/30
