Three brothers, Justin, Jared, and Jonathan decided to buy a present for their mom's birthday. Justin gave decided to spend 1/4
of his savings on the present, Jared said he will contribute 1/3 of his money, and Jonathan was willing to put in 2/5 of all he had. Each brother invested exactly the same amount of money and they bought a vase that costed $33.00. How much money did each boy have before the purchase?
I believe that, if there are three brothers and each invested the same exact money to make a total of $33.00, each brother would have invested $11.
Jonathan's was different, as he invested 2/5. 11 divided by 2 is 5.5, in which 5.5*11 would equal 27.50. The rest was simply their denominator times $11. Jared had $33 dollars before the investment, and Justin has $44.
For this case we have the following expression: 5x3 + 40y6 Common factor 5: 5 (x3 + 8y6) Factoring the expression within the parenthesis we have: 5 ((x + 2y2) (x2 - 2xy2 + 4y4)) Answer: The factored expression is given by: 5 ((x + 2y2) (x2 - 2xy2 + 4y4))
Sorry for taking so long, it wont let me type a while ago. I have it all fix now hehe. I took a picture of my work, ask me if you still don’t understand.
