Sum of the digits of a two digit number is 9. when we interchange the digits the new number is 27 greater than the earlier number. find the number

36

Step-by-step explanation:

Because the sum of 2 number is 9 so we have all posible number with sum is 9:

18, 27, 36, 45, 54, 63, 72, 81, 90

When we intercharge it, it become 27 greater than the original number, so that number would be:

18 => 81 (63 greater) wrong

27 => 72 (45 greater) wrong

36 => 63 (27 greater) right

So 36 would be the number that you are looking for!

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥
