Answer:
Angles BCF and EFH
Step-by-step explanation:
When two parallel lines are crossed by another line (the transversal), the angles in matching corners are called corresponding angles. DCF and GFC isn't the correct answer because those would be vertical angles. GFC and BCA would not be corresponding because they do not fall in matching corners. And same with EFH and BCA. Therefore, BCF and EFH would be corresponding.
36,00÷ 12= 3,000 so that would be the average monthly loss.
P = 4r + 3t
4r = p - 3t
r = (p - 3t)/4
Answer:
17
Step-by-step explanation:
Let us suppose two years ago my brother's age was x years
Then, my age was 3x
Three years from now, my brother's age will be (x +2+3) = (x+5) years
And my age will be (3x+2+3) = (3x+5) years
But it is given that i will be twice as old as my brother.
So, 2(x+5)= (3x+5)
or, x= 5 years
So my brother's present age is 5+2= 7 years
And my age is 5*3+2= 17 years
Question # 17 Solution
Answer:

Step-by-step Explanation:
The given expression

And we have to solve for x₁
So,
Lets solve for x₁.

Multiply both sides by x₂ - x₁




Divide both sides by -m


Therefore, 
Question # 23 Solution
Answer:

Step-by-step Explanation:
The given expression

And we have to solve for n
So,
Let's solve for n.

Multiply both sides by b.

Factor out n.

Divide both sides by -b + x.
