Answer:
The relationship is proportional ✧
If the integers were all the same, then each one would be 1/3 of 138 = 46 .
They're not all the same, but they're consecutive, so you can find them easily.
Just start with your 3 copies of 46, take ' 1' away from one copy, and add it
to another one. You haven't changed their sum. You just made one of your
copies 1 less than 46, and you made another one of them 1 more than 46.
Now you have 45, 46, and 47, and that sure looks like an answer to me.
Isn't that easy ... you only had to use some brain instead of a lot of messy
algebra. That's what 'Brainly' might be all about, I guess.
Answer:
The opposite or absolute value is 5.2
Answer:
One plane has a speed of 450 km/h and the other has a speed of 900 km/h.
Step-by-step explanation:
I am going to say that:
The speed of the first plane is x.
The speed of the second plane is y.
One plane is flying at twice the speed of the other.
I will say that y = 2x. We could also say that x = 2y.
Two airplanes leave an airport at the same time, flying in the same direction
They fly in the same direction, so their relative speed(difference) at the end of each hour is y - x = 2x - x = x.
If after 4 hours they are 1800 km apart, find the speed of each plane
After 1 hour, they will be x km apart. After 4, 1800. So
1 hour - x km apart
4 hours - 1800 km apart
4x = 1800
x = 1800/4
x = 450
2x = 2*450 = 900
One plane has a speed of 450 km/h and the other has a speed of 900 km/h.
