If, for example, you had x on one side and x on the other, then subtracting x from both sides "disappears" x. If no other power of x shows up on either side, then your equation either has no solution or is always true.
Step-by-step explanation:
angle AOB = x+3
angle AOC = 2x + 11
angle BOC = 4x-7
angle AOC = angle AOB + angle BOC
=> 2x +11 = (x+3) + (4x-7)
2x +11 = 5x - 4
=> 3x = 15
x = 5
subst x = 5 in the given formulas
angle AOB = x +3 =8
angle AOC = 2x + 11 = 21
angle BOC = 4x - 7 = 13
Answer:
27 cubic feet
Step-by-step explanation:
A pyramid is always 1/3 of a cube when it has the same base as a pyramid.
ALSO, thats why the volume of a square pyramid has 1/3 in it.
So, if the volume of this pyramid is 9 cubic feet then:
9 x 3 = 27 cubic feet
Hope this helps!
36/ (9 - 3) = 6
Cause:
9 - 3 = 6
Then:
36/6 simplified equals 6
So, your answer is 36/(9 - 3) = 6
Hope it helps! Good luck friend! :3
Answer:
07:45 or 7:45
Step-by-step explanation:
On a clock, the shorter hand shows the hour of the day, while the longer hand shows the minute. The clock is divided into 12 hours and 60 minutes. In this case, the shorter hand is between 7 and 8, and the minute hand is right at 45, meaning that the time is 07:45. Hope this helps!
