5x - 1 = 15x - 101
101 - 1 = 15x - 5x
100 = 10x
100/10 = x
x = 10
How this has been solved is by bringing the equations with (x) to one side and solving them and solving the other numbers on the other side..
That is the wrong answer. I just took the and got it wrong the right answer is (-4,-1).
Let’s find the volume of the small cubes.
1/3^3
1/27
Now multiply this by 567
567•(1/27)
21
The volume of the box is 21 inches cubed.
Let t = number of hours
The first candle starts at 8 inches.
It burns at 7/10 inch per hour, so in t hours it burns (7/10)t inches.
After t hours, its length is 8 - (7/10)t
The second candle starts at 6 inches.
It burns at 1/5 inch per hour, so in t hours it burns (1/5)t inches.
After t hours, its length is 6 - (1/5)t
You want the lengths to be equal, so the equation is
8 - (7/10)t = 6 - (1/5)t
