Answer:
10.5.
Step-by-step explanation:
By similar triangles:
IJ / 21 = 8 /(8+8) = 1/2
IJ / 21 = 1/2
IJ = 1/2 * 21
= 10.5.
First no. = x
Second no. = y
Equation Formation
x + y = 55..........equation (i)
x - y = 1..............equation (i)
x = 1+y
1 + y + y = 55
1 + 2 y = 55
2 y = 55-1
2 y = 54
y = 27
x=27 + 1
x =28
Answer = 28 , 27
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
Answer:
6 because 6+15=21 and 21+6=27
