Answer:The equations are equivalent so there are an infinite number of solutions.
Step-by-step explanation:
He assumes that 60-x and 2x-6 are vertical angles, so he equated these two expressions.
60-x=2x-6
60+6=2x+x
66=3x
x=22
Answer:
it went from 4 then 1 then 11
Step-by-step explanation:
No. Every quadrilateral with 4 congruent sides is a parallelogram.
3y+2y-1=4
5y=5
Y=1
Y would equal 1 because 5 divided 5 is equal to 1.
