Three multiplied by the sum of 4 and a number is the same as 18 more than the number. find the number.
if n is "the number," which equation could be used to solve for the number?
a. 3n + 4 = n + 18
b.4(3 + n) = n + 18
c.3(4 + n) = n + 18

*let m∠cob = 50°30’, m∠aob = 70° and m∠aoc = 20°30’. could point c be in the interior of ∠aob? why? a. point c could be the interior of aob but it is not the only case b. point c is the interior of aob c. point c is not the interior of aob d. the given is not possible for the plane geometry answer
