Answer:
x=-5, y=-8. (-5, -8).
Step-by-step explanation:
-x+2y=-11
5x-8y=39
---------------
5(-x+2y)=5(-11)
5x-8y=39
---------------------
-5x+10y=-55
5x-8y=39
--------------------
2y=-16
y=-16/2
y=-8
-x+2(-8)=-11
-x-16=-11
-x=-11+16
-x=5
x=-5
I would think of it as this but i could be wrong.
A right angle is 90 degrees and if you put 1/6 into a decimal it would be 6.
90-6<span>=84
so 84 degrees is missing of the right angle.</span>
Answer:
32 years old
Step-by-step explanation:
Reverse what the teacher said. Half 120 to get 60. Subtract 28 from 60. The teacher is 32.
When line is parallel to y axis
Volume is Length x width x height divided by 3. You have the length and the width. which equals 24. (6x4). The volume that is present is 72... the last thing you do in the equation is divide by three so multiply 72 by 3 and get 216. This is the LxWxH. Like I said before you have the L and the W, which is 24. You would divide 24 from 216. The Height is 9cm.
