Well when two angles are supplementary they equal 180.
So if angle A is 80 degrees then that would mean that angle B equals 100 degrees.
Hope This Helped :)
Answer: first answer choice (1/3) (p+45)
Step-by-step explanation:
to do this, factor out 1/3 from each element
so divide 1/3 p by 1/3 and 15 by 1/3
(1/3 p) / (1/3 ) = p
15 / (1/3) = 15 * 3 = 45
now put 1/3 outside of the parentheses
(1/3) (p+45)
Answer: y= −12
Step-by-step explanation:
Answer:
X-intercept = -3 and y-intercept = 6
Step-by-step explanation:
We can start off by isolating the y term. To do that, we must add 2y to both sides to get
Now, we must add 12 to both sides and the y term will be all alone on the right side:
Now, to have only y on the right side, we must divide by 2 to get:
In slope-intercept form, b is the y-intercept, and 'b' in this equation is 6. We have our y-intercept.
To find our x-intercept, y must be equal to zero. We can plug in that value for y and solve for x:
We can start off by subtracting 6 from both sides to get:
We can then divide both sides to get 
when y is equal to 0. Thus, we have our x-intercept.
The answer is The Multiplication or Division Principle of Equality. It states that if you multiply or divide both sides of an equation by an expression, the resulting the equation will be equivalent to the original equation.
14x = 56
x = 4 <-- Divide both sides by 14
So, x is equal to 4.<span />
