Answer:
3.8
Step-by-step explanation:
Let's add 5x to both sides of the equation...
Then, let's add 75 to both sides of the equation...
Divide by the coefficient of x, (35)...
Answer:
$75000/year
$6250/month
Step-by-step explanation:
1500 ft²*$50/(ft²*year) = $75000/year
1 year = 12 month
$75000/12 month= $6250/month
Answer:
8 sides
Step-by-step explanation:
let x be the exterior angle then 3x is the interior angle
interior angle + exterior angle = 180° , then
x + 3x = 180
4x = 180 ( divide both sides by 4 )
x = 45
the sum of the exterior angles of a polygon = 360°
since the polygon is regular with each exterior angle = 45°, then
number of sides = 360° ÷ 45° = 8
