Answer:
3/4
Step-by-step explanation:
28 total but 12 are boys so girls = 28 - 12 = 16
Ratio of boys to girls
= 12/16
= 3/4
Let smaller number be x/2 and the larger number x.
x/2 + x = 81
x/2 + x = 3x/2
3x/2 = 81
3x = 162
x= 54
The smaller number is 54/2= 27 and the larger number is 54.
Answer:
The value of x in the 2nd quadrant is always negative.
Step-by-step explanation:
There form four zones in the coordinate plane by placing the coordinate axes i.e. X-axis and Y-axis. The top right zone is called the 1st quadrant and 2nd, 3rd and 4th quadrants are the zones obtained by rotating in anticlockwise about the origin.
Since the 2nd quadrant is placed at the top left zone, so, we have to move in the negative x-direction along or parallel to the X-axis and to move in the positive y-direction along or parallel to the Y-axis.
Therefore, the value of x in the 2nd quadrant is always negative.
