Answer:
130
Step-by-step explanation:
The two angles add up to 180 since they form a straight line
4y-50 + 3y+55 = 180
Combine like terms
7y +5 = 180
Subtract 5 from each side
7y-5+5 = 180-5
7y = 175
Divide each side by 7
7y/7 =175/7
y =25
The obtuse angle is greater than 90 degrees
3y+55
3(25) +55
75+ 55
130
The answer is B. The slope is -4 and the y-intercept is 1, so the equation is
<em>y=-4x+1</em>. That matches with option <em>B.
</em>

The solution to the equation is x = 4
<h3>What are linear equations?</h3>
Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
<h3>How to determine the solution to the system?</h3>
A system of linear equations is a collection of at least two linear equations.
In this case, the equation is given as
(x + 20)/2 = 3x
Multiply both sides of the equation by 2
x + 20 = 6x
Subtract x from both sides of the equation
5x = 20
Divide both sides of the equation by 5
x = 4
hence, the solution to the equation is x = 4
