Answer:-3
Step-by-step explanation:do the distributive property. So let's simplify it more: -8g+6=30. Minus the positive 6 to make it a zero then minus the 30 to make it a 24. -8g=24 is what's left. Divide both sides by negative 8: g= -3
Step-by-step explanation:

Answer:

Step-by-step explanation:
Since the height isn't given, we assume it to be "h" (of cylinders). And the answer will be in terms of "r" and "h".
The area of 1 arm is given, so the area of 2 arms would be:

Now, area of 2 cylinders would be the formula:

So, total area is A_arm PLUS A_cyl. The fractional area the arms are would be gotten by taking expression A_arm divided by A_total.
Shown below:

We simplify further:

THis is the answer.

Answer:
x = 80, y = 122
Step-by-step explanation:
I got this equation by using vertical angles to create a complimentary angle pair (they sum to 90 degrees).
3/4x+2/5x-2=90°,
23/20x - 2=90°,
23/20x = 92°,
92/(23/20)
20/(1/4)
20(4)
= 80.
Since the angles are a linear pair on the left side(they sum to 180 degrees). Just subtract 180 from 3/4x-2 and substitute x into the expression.
180-(3/4(x)-2), 180-3/4(80)+2 = 120+2 = 122
