You should use your calculator for such simple sums. It is far quicker and involves fewer key depressions than posting the question on WA.
the sum of 54 and 46 is equal to 100 54 + 46 = 100
6/20=54/b 54/b*54 6/20*54/1= 324/20= 16.2 b=16.2
The two equal numbers that have the sum of 54 are 27 and 27.
54 (5 + 4) x 6 = 54
54 x (1 - (20/100)) = 54 x 0.8 = 43.2
16+18+20= 54
54.
the sum of 54 and 46 is equal to 100 54 + 46 = 100
what prime numbers have the sum of 54
x+y=54 x-y=20 solving it,we get x=37 and y=17
If two prime number have a sum of 54 they cannot have a sum of 84, and conversely.
319+54=373
54 + 37 = 91
16 18 20
54 + 58 = 112
6/20=54/b 54/b*54 6/20*54/1= 324/20= 16.2 b=16.2
54 + 67 = 121 54 x 67 = 3618
