For what value of x if 45x7 is divisible by 9. |
|
Answer» Step-by-step EXPLANATION: from the divisibility rule of 9 if the sum of the NUMBER is divided by 9 then the entire number will be divided by 9 here the number = 45x7 but 16 is not divisible by 9 if we add two then it will be 18 and will be divisible by 9 So LET x = 2 4 + 5 + 2 + 7 = 18 which is divisible by 9 4527 ÷ 9 = 503 |
