The fractions you use must be the correct conversion factors.
1 km = 1000 m, so you can have the fraction (1 km)/(1000 m) or the fraction (1000 m)//(1 km). You must choose the correct one for this problem.
1 hr = 60 min, so you can have the fraction (1 hr)/(60 min) or the fraction (60 min)/(1 hr). Again, you must choose the correct one for this problem.
The important thing is to choose the correct fraction from the choices.
How do you know which conversion fractions to use?
You look at the given units and the units you want.
You must pick the conversion fraction that will cancel out the units you DON'T want, leaving the units you want.
You have a speed in km/hr.
km is in the numerator. To cancel out km, you must pick the conversion fraction that km in the denominator.
hr is in the denominator. To cancel out hr, you must pick the fraction that has hr in the numerator.

Notice that km and km cancel out leaving m.
Also, hr and hr cancel out leaving min.
Step-by-step explanation:
since in a triangle each side must be shorter than the sum of the other 2 sides (otherwise the end points cannot connect, and there is no triangle), the necessary inequality condition must be
side < 1 + 2 = 3
so,
side < 3
for a lower limit let's go through the cases
1 < 2 + side (is always true)
2 < 1 + side
1 < side (side must be larger than 1)
and again
side < 1 + 2 = 3
side < 3
so the full restriction for the third side is
1 < side < 3
Answer:
27 feet.
Step-by-step explanation:
This is quite simple. As a square has equal lenght and width we can tell that 6x6=36. So each side has a lenght of 6 feet. With only 3 sides needed for fencing, 6x3=27. Mrs. Roberts needs 27 feet of fencing.
Answer:
4x+3
How: -2x - (-6x) = 4
3 cannot be added there you go
32.0 would be your answer
