To find the number ( d ), we can set up the equation based on the statement: ( 2d + 3 = 12 ). Subtracting 3 from both sides gives us ( 2d = 9 ). Dividing both sides by 2, we find ( d = 4.5 ). Thus, the value of ( d ) is 4.5.
2*(n+3)
2 (N + 3)
The sum of a whole number and a fraction is a mixed number.
12
the number is 11
2*(n+3)
2 (N + 3)
2(n+3)
The number is 7.
2(x + 3)= 5? x + 3 = 2½ x = -½
Where n = any number, n(12+3)
The sum of a whole number and a fraction is a mixed number.
2a+3>49
the number is 11
12
3, 12, 30
It is 17 because (17+19)/3 = 12
