Answer:
A. x=3
Step-by-step explanation:
4(5x+3)=14x+30
multiply 4 to 5x and multiply 4 yo 3
20x+12=14x+30
move terms
20x-14x=30-12
subtract 20x to 14x and subtract 30 to 12
6x=18
divide both sides by 8
x=3
Answer:
<18 = 40
Step-by-step explanation:
<3 = <19 since they are alternate exterior angles and alternate exterior angles are equal for parallel lines cut by a transversal
<19 = 140
<19+<18 = 180 since they form a straight line
140 + <18 = 180
Subtract 140 from each side
140-140 + <18 = 180-140
<18 = 40
