The right answer is Option D.
Step-by-step explanation:
Given equations are;
2x+4y=3 Eqn 1
x+3y=13 Eqn 2
When we use subtraction-addition method, we make one of the variables same with opposite signs so that only one variable remains after addition or subtraction.
In the given problem, we will multiply Eqn 2 with "-2" so that the x variables become equal and then we can add both the equations and solve for y.
Therefore,
The first step will be to multiply the second equation by -2 to solve the linear system of equations.
The right answer is Option D.

Answer:
w = 10.4
Step-by-step explanation:
step 1 - You add 16 and 4 which is 20
Step 2 - Than you subtract 20 from both sides so it will be 20 - 20 = 0 and 27.28 - 20 = 7.28
Step 3 - Now you take 7.28 ÷0.7 = 10.4
So the answer is 10.4

Answer:
Angle HAB and Angle FAE are congruent angles
Step-by-step explanation:
we know that
Two angles are supplementary if their sum is equal to 180 degrees
In this problem
m∠FAH+m∠HAB=180° ----> by a linear pair
Remember that
A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. A linear pair of angles must add up to 180 degrees
m∠FAH+m∠FAE=180° ----> by a linear pair
therefore
m∠HAB=m∠FAE -----> by vertical angles
Angle HAB and Angle FAE are congruent angles
