(((A 15.7)))..............
Total road length is 36 miles.
If one crew’s rate is x miles/day, the other is 1.4x miles/day.
The collective distance per day is x+1.4x,
so in five days the distance is 5(x+1.4x).
Set that equal to the total distance:
5(x+1.4x)=36
simplify:
x+1.4x=7.2
x(1+1.4)=7.2
x(2.4)=7.2
x=3
Step-by-step explanation:
The negative of a number may sometimes be greater than the number itself.
The negative of a negative number is positive which will give a greater number than the number itself. But the negative of a positive number is negative which is smaller than the number itself
Let us take a few examples
-(-1) = 1, 1>-1
-(1) = -1, 1>-1
Evrey 1mile=1.609344km
so 6km=6×1.609344miles
I think its 20 pounds per 17 square feet (simplest form)
