Are you good at math?

Ann is currently 84 and Joan is currently 12. 12x7=84 in 6 years, Ann will be 90 and Joan will be 18. 90/18=5 hope that helps!

In order to answer this question properly, we would need to set up an algebraic equation, both sides being equal, in terms of Joan's age. So, we will set Joan's current age equal to "x". Therefore, Ann's current age is 7 times "x" Joan's current age = x Ann's current age = 7x In order for that side of the equation to equal Anne's future age, we need to add 6 years to Ann's current age. Ann's age in 6 years = 7x + 6 Now, we have enough information to make a balanced equation on the other side. So, we know that when Joan is 6 years older (x + 6), Ann will be 5 times older. Joan's age in 6 years = (x + 6) Anne's age in 6 years = 5(x + 6) We have found 2 equations for Anne's age in 6 years. Now, we have to set them equal to each other, and find what x equal to find Joan's current age. 7x + 6 = 5(x + 6) 7x + 6 = 5x + 30 7x = 5x + 24 2x = 24 x = 12 12 is Joan's current age. Anne's current age is 7 times that, which is 84. Hope that this was helpful, and that it gives an example of what to do for the other problems. Good luck!
