Which statement could be used in step 2 when proving x =
30?
given: mzorp = 80°
mzorn = (3x + 10)°
prove: x= 30
statements
1. mzorp - 80°, mzorn-(3x +10)
reasons
1. given
p
80° (3x + 10)
o zorp and zorn are a linear pair
o zorp and zorn are vertical angles
o 80 = 3% +10
o x = 30

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
