More algebra pretending to be geometry.  These questions should be banished from the planet.

A transversal across parallel lines generates the usual congruent and supplementary angles; here our pair are supplementary, adding to 180 degrees.  Geometry done.

(2x + 12.8) + 117.6 = 180

2x = 180 - (12.8 + 117.6) = 49.6

x = 49.6/2 = 24.8

Answer: 24.8

One number is 9 more than another. if the sum of the two numbers is 171, find the two numbers
allochka39001 [22]
Let x be the 1st number
x + 9 be the second number

Equation:
x + x+9 = 171

Solution:
2x + 9 = 171
2x = 171 - 9
2x = 162
x = 81
x + 9 = 90

81 + 90 = 171

PLEASE HELP, THANK YOU! :)
elena-s [515]

Steps to solve:

-4z + 4 + 12z = 3z + 4 + 5z

~Combine like terms

8z + 4 = 8z + 4

~Subtract 4 to both sides

8z = 8z

~Divide 8 to both sides

0 = 0

All real numbers are solutions.

Set builder notation: {x | R}

This is an identity since every value can be a solution to the equation.

Best of Luck!
