Sorry if I'm wrong
a = 10
this what I did
7 - 3 = 4 ÷ 0.4 = 10
Answer:
102 degrees
Step-by-step explanation:
Since the two angles are same side interior that would mean they sum up to 180 degrees.
180-78=102 degrees

Answer:
x=-6, y=0
Step-by-step explanation:
Use the 3x-9y=-18 equation and add 9y to both sides to have 3x on its own on the left side. Then, divide by 3 on both sides. Then you'll have x=-6+3y. Plus this back into the 5x+4y=-30 equation and you'll get 5(-6+3y)+4y=-30. Use the distributive property and you'll get -30+15y+4y=-30. Simplify and get -30+19y=-30, then add 30 to both sides and you'll get 19y=0. Divide by 19 on both sides and you'll get y=0. Now that we know y=0, plug that back into the 5x+4y=-30 equation, and you'll get 5x+4(0)=-30. Simplify and you'll get 5x=-30. Divide by 5 on both sides and you'll get x=-6.
Angle 6 and Angle 4 are not corresponding they are consecutive angles.
