How many are 13 x 13 ?

2x - 20 = 32 20 - 3x = 8 6x - 8 = 16 -13 - 3x = -10

0if x and y vary inversely and y=6 as x=7, what is the constant of variation?

*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
