Answer:
16
Step-by-step explanation:
let the number be x , then
x = 15 ( multiply both sides by 4 to clear the fraction )
3x = 60 ( divide both sides by 3 )
x = 20 , then
× 20 = 4 × 4 = 16
Answer:

Answer: A=16
Step-by-step explanation:
24=a+8
-a=8-24
-a=-16
Answer:
Sum of the interior angles = 1440 degrees.
Step-by-step explanation:
There are a total of 10 interior angles in the decagon. Now for all polygons the sum of all the exterior angles is 360 degrees. There are 10 exterior angles in the decagon and, since it is regular, each of them = 360/10 = 36 degrees. Each interior angle therefore measures 180 - 36 degrees and the sum of the interior angles is this value times ten.
360 / 10 = 36.
180 - 36 = 144.
10 * 144 = 1440 degrees.
Answer:
10
Step-by-step explanation:
9% of $20,000 is $1,800
20,000 - 1,800 = 18,200
18,200 - 1,800 = 16,400
16,400 - 1,800 = 14,600
14,600 - 1,800 = 12,800
12,800 - 1,800 = 11,000
11,000 - 1,800 = 9,200
9,200 - 1,800 = 7,400
It takes 7 years to get 7,400 and to the nearest tenth is 10
