Let x represent the smallest angle. Then the largest is 3x, and the remaining angle is 180-4x. The problem statement tells us
.. 3x > 180 -4x > x
Adding 4x gives us
.. 7x > 180 > 5x
or
.. 36 > x > 180/7 = 25 5/7

The angles, smallest to largest, are
.. x, 4(45 -x), 3x
where 25 5/7 < x < 36

The angles could be, for example, any of ...
.. 26°, 76°, 78°
.. 30°, 60°, 90°
.. 32°, 52°, 96°
.. 35°, 40°, 105°
and an infinite number of other possibilities.

Marneshia walked three over eight of a mile in three over five of an hour. What equation can be used to calculate her unit rate

Rama09 [41]

3/8 mile in 3/5 hour
$\frac{ \frac{3}{8} }{ \frac{3}{5} }$
we want to find miles per hour or m/1h
convert 3/5 to 1 by multiplying it by 5/3
keep the fraction the same by multiply ing the whole thing by
$\frac{ \frac{5}{3} }{ \frac{5}{3} }$ to get

$\frac{ \frac{15}{24} }{ \frac{15}{15} }$ =
$\frac{ \frac{5}{8} }{ 1}$ =5/8 miles per hour
