Answer:
What is missing is -5x - 20
Step-by-step explanation:
To find this, simply solve for the parenthesis as if it were a variable of its own. This will allow you to see exactly what is missing.
8x - (x - 20) = 2x - (_______)
8x - x + 20 = 2x - (_______)
7x + 20 = 2x - (_______)
5x + 20 = - (_______)
-5x - 20 = (_______)
So the answer for the parenthesis is -5x - 20
Answer:

Answer:

Step-by-step explanation:
The two angles are inside a right angle. The small box signifies a right angle/ 90° angle.
Therefore, the sum of the angle measures must equal 90. We can set up an equation.

Combine the like terms on the right side. The 2 constants: 56 and 16 can be added.


Since we are solving for x, we must isolate the variable. 72 and x are being added. The inverse of addition is subtraction, so subtract 72 from both sides.


x is equal to 18 and choice A is correct.
Answer: y=17-5x/-9
Step-by-step explanation: 5x-9y=17
-9y=17-5x
Y=17-5x/-9
You can’t go any further than that because you can’t combine unlike Terms on the right side of the equation.
Answer:
D. 267.9 in3
Step-by-step explanation:
So we know the diameter is 16 inches.
So we need to find the radius and we do that by: 16/2 = 8 then it is reduced by half: 8/2 = 4
Now we need to find the volume.
V= 4/3 times 3.14 times 4^3= 268.08
So we would need to round which would give us 267.9 in3.
Therefore the answer is the D. 267.9 in3.
I hope this helps!!!
