Holly missed 7 out of 185 school days this year. Approximately what percent of school days was holly in attendance?
MariettaO [177]
It 96%
subtract 7 from 185 that'll equal 178
use the 178 as the numerator for the days she attended
and 185 as the denominator as the days in total.
178/18= x/100 then solve for x and youll get 96 over 100 or 96%

A parallelogram is a quadrilateral. Therefore, the sum of its interior angles is 360 degrees.

If we know that one angle is 37 degrees, then the sum of the other three angles is: x + 37 = 360

The sum of the other three angles = 323 degrees

Hope this helps!! :)
