Answer:
The solution is x=4.75 and y = -22
Step-by-step explanation:
To find the solution to the system of equations, we will follow the steps below:
3.2x + 0.5y = 4.2 --------------------------------------------------------------------------(1)
-1.6x -0.5y = 3.4 ----------------------------------------------------------------------------(2)
add equation (1) and equation (2)
1.6x =7.6
Divide both-side of the equation by 1.6 to get the value of x
1.6x /1.6 =7.6/1.6
x =4.75
substitute x = 4.75 into equation (1) and solve for y
3.2(4.75) + 0.5y = 4.2
15.2 + 0.5y = 4.2
subtract 15.2 from both-side of the equation
15.2 - 15.2 + 0.5y = 4.2-15.2
0.5y = -11
Divide both-side of the equation by 0.5
0.5y/0.5 = -11/0.5
y = -22
The solution is x=4.75 and y = -22

Answer:
D. 110°
Step-by-step explanation:
we know that
When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called <u><em>corresponding angles</em></u>.
When the two lines are parallel Corresponding Angles are congruent
In this problem
The transversal line is t
The two lines that are crossed by the transversal are line l and line m
Lines l and m are parallel
therefore
----> by corresponding angles
