I am thinking of a number that has a four in the hundreds place and a two and the one's place. When you round it to the nearest hundred it is 500, What is my number?

either 452, 462, 472, 482, 492

Step-by-step explanation:

4 in the hundreds place -- 4??

two in the ones place -- 4?2

round to nearest hundred means tens place ≥ 5

either 452, 462, 472, 482, 492

there is not enough information to narrow it down to one number

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

step-by-step explanation: 2
