Answer:
-9,-21
Step-by-step explanation:
let the numbers be x and y and x>y
x-y=12
y=2x-3
x-(2x-3)=12
x-2x+3=12
-x=12-3
-x=9
x=-9
y=2(-9)-3=-18-3=-21
Answer:
1.2, 2, 2.8
Step-by-step explanation:
Hey there,
15x=6
=> 5x=2, 3x=1.2, 7x=2.8
Hope this helps :)
1/4 = .25 or 25%
a(postcard stamps) = .25(percentage of postcard stamps) * 900(total of stamps)
900 * .25 = 225
They sold 225 postcard stamps
To check:
225 * 4 = 900
The central angle and the length of arc are related by the formula:
Length of arc = (θ/360) * 2πr
Where θ = Central angle.
If the central angle is one quarter of the entire circle, the length of arc would also be one quarter of the entire circumference of the circle.
