The number at the midpoint of these two numbers is (15 + 27)/2 = 21
It is: 15
3(5-x) = 27 15 - 3x = 27 15 - 3x + 3x = 27 + 3x 15 = 27 + 3x 15 - 27 = 27 - 27 + 3x -12 = 3x -4 = x To check 3(5- -4) ? 27 15 - -12 ? 27 15 + 12 = 27
The number 3
3
The answer is 27. 10+15=25. 25+2=27.
It is: 15
, 21, 22, 24, 25, 26, 27, 28
To find the number that is in the exact middle of two numbers, add the numbers and divide by 2.25 + 15 = 40. 40 divided by 2 = 20.26.9 is one of infinitely many values between 27 and 15.
3(5-x) = 27 15 - 3x = 27 15 - 3x + 3x = 27 + 3x 15 = 27 + 3x 15 - 27 = 27 - 27 + 3x -12 = 3x -4 = x To check 3(5- -4) ? 27 15 - -12 ? 27 15 + 12 = 27
To find the next number in the sequence 12, 15, 27, 27, 42, we can look for a pattern in the differences between the numbers. The differences are 3, 12, 0, and 15, respectively. The pattern in the differences suggests an increase, so the next difference could be 3 more than the last difference (15), which is 18. Adding 18 to the last number (42) gives us 60. Thus, the next number in the sequence is 60.
There cannot be any number between two identical numbers.
The number 3
3 will go into both 15 and 27. 1 will go into any number, so also 1.
180*15/100 = 27
27
3, 9, 15, 21, 27, 33, 39, 45.
They are 11, 13, 15, 17, 19, 21, 23, 25, 27 and 29.
