Answer:
y = 130
Step-by-step explanation:
Those two exterior angles are equal (property of parallel lines)
y is thsupplement of 4x - 14
2x + 18 = 4x - 14 Add 14 to both sides
2x + 18 + 14 = 4x - 14 + 14 Combine like terms
2x + 32 = 4x Subtract 2x from both sides
2x-2x+32=42-2x Combine
32 = 2x Divide by 2
32/2 = x
16 = x
============
4x - 14 =64 - 14 = 50
y = 180 - 50
Bro all of them are correct
Let's call the number we're looking for . We know that is twice as much as .
Twice as much as a number simply means the double of that number, and in turn the double of a number means to muliply that number by 2.
So, in order to obtain , you have to multply by 2. In formula, you have
or simply
10x9-5(8)=34
