Answer:
7 x 2 + 31
Step-by-step explanation:
Equals to the bottom line answer is 7
4(2x-5)
8x-20
it is equal to 8x-20 because you simplify it and it turns into that.
HOPE I HELPED!!!
Simplify both to 1/2 because both numerators are half of their denominators. Then multiply straight across to 1/4.
Step-by-step explanation:
Given :
Given that lines a and b are parallel, angles 1 and 5 are congruent because they are corresponding angles, and angles 1 and 4 are congruent because they are vertical angles
To find : by which property are angles 4 and 5 congruent
Solution :
We know that if two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent.
Also, we know that if two things are equal to the same thing then they are equal to each other . In this case, we can say that if two angles are congruent to a third angle, then they are congruent to each other. As angles 4 and 5 are both congruent to angle 1, they are congruent to each other but angles 4 and 5 are alternate interior angles. So, if parallel lines have a transversal, alternate interior angles are congruent.
