Answer:
x = 17
Step-by-step explanation:
Line l and m are two parallel lines cut across by the transversal line, therefore, the angle measuring 53° and (8x - 9)° are interior angles on the same side. Interior angles on the same side are supplementary.
Therefore:
53° + (8x - 9)° = 180°
Solve for x
53 + 8x - 9 = 180
Collect like terms
53 - 9 + 8x = 180
44 + 8x = 180
Subtract 44 from both sides
44 + 8x - 44 = 180 - 44
8x = 136
Divide both sides by 8
8x/8 = 136/8
x = 17
The answer to that equation is X= -1
Christy did not get enough because 12 times 8 = 96. she needs 4 for inches.
Answer:
A. 10
Step-by-step explanation:
Based on the midsegment theorem, thus:
2x + 7 = ½(7x - 16)
Multiply both sides by 2
2(2x + 7) = 7x - 16
4x + 14 = 7x - 16
Combine like terms
4x - 7x = -14 - 16
-3x = -30
Divide both sides by -3
x = 10
