Answer: A) 3x + 5x - 4 = 1
<u>Step-by-step explanation:</u>
The second equation is y + 4 = 5x. Solve this equation for y by subtracting 4 from both sides. --> y = 5x - 4
Now replace "y" in the first equation with "5x - 4".
3x + y = 1
--> 3x + (5x - 4) = 1
Yes
Divide it by sixty and multiply

Answer:
22
Step-by-step explanation:
Because of the parallel lines, angles A and DCE are congruent.
Also, angles E and BCA are congruent.
That makes angles B and D congruent.
m<DCE = 70 and m<EDC = 50, so m<E = 60
m<BCA = m<E = 60
