Let the numbers be x and y, then
2x + y = 47 . . . (1)
x + 3y = 56 . . . (2)
(2) x 2 => 2x + 6y = 112 . . . (3)
(1) - (3) => -5y = -65 => y = -65/-5 = 13
From (2), x + 3(13) = 56 => x = 56 - 39 = 17
The two numbers are 13 and 17.
C because its a line segment
(new -original)/original * 100
(36-20)/20 * 100
16/20 * 100
.8*100
80
80% increase
(-y + 5a - 4) + (3y - a - 5) is simplified to 2y + 4a - 11
If the angle is 1/12 of the circle, and a circle is 360 degrees, then our answer will be 1/12 of 360.
1/12 * 360 = 30 degrees
The answer is 30 degrees.
