Question:factorise and evaluate 99x1099 x9
solve for x: 4(x+3)=12
Lisa has 60 lollies to share, she gave each of her friends the same number of lollies and had 5 left over for herself. If Lisa had fewer lollies than any of her friends, how many friends did lisa share her lollies with.
The last digit of a 6 digit number is 2. If the two is moved to the start of the number, the new 6 digit number is only a third of the original number. Find the original number:
2abcde x 3 = abcde2 ( start of working out)
Plz show workings out thank you so much in advance
Answers:99x^9 (x1); pulled out 99x^9... x+3 = 3; divided each side by 3; next subtract 3 from each side and you get x=0 let x = # lollies per friend, let f = # friends; 60 5 = 55; x*f = 55. so either 11 friends with 5 lollies each or 5 friends with 11 lollies each < which is the answer because Lisa had less lollies than her friends 6abcde=abcde2 wow, that was tricky, but fun when you set up the 2abcde x 3 = abcde2, you will see only certain numbers will end up with the correct second digit. Like only 4 x 3 ends in a 2 (12), so you know e=4. Continue the process, and you will get 285,714 x 3 = 857,142 = the original number.
