Leonard made an error when he multiplied a negative by a negative and got a negative
It should look like this:
-20x + 35 + 8 = 3x
Hope this helps!
I would convert them all to the denominator 16, due to the smallest fraction and all of them can be converted to it.
1 = 16/16
1/2 = 8/16
1/4 = 4/16
1/8 = 2/16
1/16 = 1/16
1+ 2 + 4 + 8 + 16 = 31
31/16 = 1 15/16
Hope this helps!
The change in altitude after 135 seconds was a decrease of 810 meters, that is, -810 meters.
Given that a weather balloon is descending from the atmosphere, and its altitude changes by -6 meters every second, to determine what is the change in altitude after 135 seconds the following calculation must be performed:
- Amount of time x change per second = total change
- 135 x (-6) = X
- -810 = X
Thus, the change in altitude after 135 seconds was a decrease of 810 meters, that is, -810 meters.

10 & 12
x = 1st consecutive even number
x + 2 = 2nd consecutive even number
x + x + 2 = 22
2x + 2 = 22
2x = 20
x = 10
x + 2 = 12
10 and 12 are the two consecutive even numbers
