Let one number be x.
Let the other number be y.
x + y = 49
x - y = 7
Subtracting both equations,
2y = 49 - 7 = 42
--- y = 21
--- x = 21 + 7 = 28
Hence the two numbers are 21 and 28.
your answer is
5/2
if you need it simplified its
2 1/2
and in decimal form its 2.5
Answer:
1/3
Step-by-step explanation:
Simplify the following:
((36/2)/(3×9))/2
((36/2)/(3×9))/2 = 36/(3×9×2×2):
36/(3×9×2×2)
36/9 = (9×4)/9 = 4:
4/(3×2×2)
4/2 = (2×2)/2 = 2:
2/(3×2)
2/(3×2) = 2/2×1/3 = 1/3:
Answer: 1/3
