21+24
First, calculate the sum of 37 and 45, which is 82. Then, to find trice that sum, multiply 82 by 3, resulting in 246. Therefore, the number that is trice the sum of 37 and 45 is 246.
The GCF of 9 and 15 is 3. The LCM is 45.
Sum: 16 Product: 48 Difference: 8 Quotient: 3
forming a simultaenous equation where x+y=27 and x-y=3 you find that x=15 and y=12.
24 + 21 = 45 24 - 21 = 3 Therefore, the two numbers are 21 and 24.
To find the sum of 23 and 45, simply add the two numbers together. You can do this by aligning them vertically by their place values: 23 + 45 ----- Adding the units place (3 + 5 = 8) and then the tens place (2 + 4 = 6) gives you a total of 68. Therefore, the sum of 23 and 45 is 68.
3 1/2+ 6 5/8
3 + 2 = 5. (sum) 3 - 2 = 1. (difference)
1, 3, 5, 9, 15, 45 (sum = 78).
45/3-1, 45/3 and 45/3+1 that is, 14, 15 and 16.
45/3 - 2, 45/3 and 45/3 + 2 ie 13, 15 and 17
Two numbers with a sum of 47 are 1 and 46, 2 and 45, 3 and 44, 4 and 43, etc.
