Sum of all adjacent angles is 180°.
3x + 12 + x = 180
4x + 12 = 180
4x = 168
x = 42°

Answer: x = 42°

Answer:
{1}
Step-by-step explanation:
A ∩ B ∩ C means A intersection B intersection C. That means the question is asking for a set of numbers that are in sets A, B, and C.
{1} is the answer since it is the only number that is in all three sets.
x = total amount of gumballs
let's start subtracting the balls she's giving away


and we also know that after all that has been subtracted, she's only left with 5, so we can say that

Explanation: This is a linear equation because it's written in slope-intercept form or <em>y = mx + b</em> where the multiplier or the coefficient of the x-term represents the slope of the line and the<em> b</em> represents the constant term.
So the slope will be the coefficient of the <em>x-term</em> which means the number that is in front of the <em>x</em> which in this case is -5/4.
The y-intercept is the constant term which is +8
Answer:
60%
Step-by-step explanation:
Divide the amount of people who showed up by the total invited...
39/65 = 0.6
To convert a decimal to a percent, multiply the decimal by 100%...
0.6(100%) = 60%
