Complete the paragraph proof given: < 1 and < 2 are supplementary and < 2 and < 3 are supplementary prove: < 1 is congruent to < 3 by the definition of supplementary angles, m< 1+m< 2=? m< 2+m< 3=? m< 1+m< 2=m< 2+m< 3 subtract m< 2 from each side, you get m< 1=? or < 1is congruent to?i do not understand this at all, all is greatly appreciated!

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
