The length of a rectangle is 3 times the width. if the perimeter is to be greater than or equal to 104 meters. what are the poss
Naya [18.7K]
Let L = length, W = width, and formula for perimeter (each side added) is
P = 2L + 2W

The first statement tells us L = 3W so we can substitute 3W for L in the formula.
P = 2(3W) + 2W

The 2nd statement tells us to make the expression for the perimeter into an inequality where it is ≥ (greater than or equal to) 104
2(3W) + 2W ≥ 104

We only need to solve this to find the possible values for W/  
2(3W) + 2W ≥ 104
8W ≥ 104    ← result of simplifying left side
W ≥ 13    ← result of dividing both sides by 8

ANSWER: The width is greater than or equal to 13: W ≥ 13

Airplane X left the airport, flying at a rate of 400 miles per hour. Airplane Y left 2 hours later, flying at a rate of 450 mile
sergij07 [2.7K]

Answer:   i think it will take 48 hours

Step-by-step explanation:

here's how to get 48 so basically 450-400-2= 48

now if you end up doing 400 - 450 then you will get -50 if you do 400-450-2 you will get a -52 <u><em>so you want to make sure you do the biggest number first and then do the smaller numbers to get 48</em></u> like 450 - 400 - 2 and then you will have 48

i hope this helps!
