Small number=S
Large number= L
Write the equations:
S=L/4
L-S=36
Plug the first one in the second one:
L-L/4=36
3L/4=36
L=48
Then S=L/4=48/4=12
Treat ast fraction
96/132
divide by 2,3,5,7 or factors starting from 2
96/2=48
132/2=66
48/66
divide 2
48/2=24
66/2=33
24/33
divide 3 since cannot divide 33 by 2
24/3=8
33/3=11
8/11
8:11
answer is 8:11
Based on my calculations this should be correct

Answer:
Step-by-step explanation:
8x - 2y = 6
-8x + 4y = 12
2y = 18
y = 9
8x - 18 = 6
8x = 24
x = 3
(9, 3)
Answer:
D. 68 Degrees
Step-by-step explanation:
We have the hypotenuse and the adjacent, so we use cos
Cos-1 of Adjacent / Hypotenuse = 67.9756871
