Sometimes. for example, the opposite of 5 is -5, which isn’t greater than the number itself. but, the opposite of -5 is 5, which is greater.
Not if you keep the ' l ' before the ' XX ' where it belongs. If it's before, then it means take the ' l ' away from them, and you get 19 just as you should.
Now I understand this crazy question that keeps coming around.
Answer:
y = 36/5
Step-by-step explanation:
The formula for direct variation is
y = kx where k is a constant
We know y =12 and x= 5
12 = k*5
12/5 = k
The formula is
y = 12/5 x
Now find y = when x=3
y = 12/5 *3
y = 36/5
Answer:
55.734 mph
Step-by-step explanation:
Let's call the wind speed x and the time of flight t.
Then, we can write the following equation, knowing that the distance is equal speed times time of flight:
910 = (350+x) * t
660 = (350-x) * t
If we isolate t in both equations and compare its value, we have that:
910 / (350+x) = 660 / (350-x)
(350+x)/(350-x) = 910/660
350 + x = 1.3788 * (350-x)
350 + x = 482.58 - 1.3788x
2.3788x = 132.58
x = 55.734 mph
