45 = 30 + m
Subtract 30 from both sides: 15 = m
correct anser is C ; y=-45
The sum of these numbers is 563.
It depends on what x and y are.
To solve the equation "blank plus 9 times 3 equals 45," we first need to simplify the expression on the right side. 9 times 3 equals 27. Therefore, the equation can be rewritten as "blank plus 27 equals 45." To isolate the variable "blank," we subtract 27 from both sides of the equation. The solution is blank equals 18.
45 * 30 = 1350

8:30 plus 45 minutes equals 9:15. To add the two times together, you can convert 8:30 to 8:00 and add the 45 minutes to get 8:45. Then, adding another 30 minutes gives you a total of 9:15.
45 * 30 = 1350
45 + 3n = -45 Subtract 45 from both sides: 3n = -90 Divide both sides by 3: n = -30
