Answer:
Step-by-step explanation:
Let x represent the amount Peter invested at 14%. Then (x-900) is the amount he invested at 6%. His total interest earned is ...
0.14x + 0.06(x -900) = 221
0.20x = 275 . . . . . . . . . . . . . . . . add 54, simplify
x = 1375 . . . . . . . . . . . . . . . . . . . .divide by 0.2; amount invested at 14%
(x-900) = 475 . . . . . . . . . . . . . . . amount invested at 6%
Peter invested $475 in the 6% account and $1375 in the 14% account.
Yes It is a right triangle

400d=p
All you have to do is multiply 400 pounds by however many days you need to figure out. For example, if you wanted to find how many pounds an Arian elephant eats in 4 days, you would multiply 400*4=p. 400*4=1,600 pounds. Hope this helps :)
Set up a proportion. 3/4 = h/5. After cross multiplying you gey 4h=15. Divide both sides by 4 and you get h=3.75ft
To solve the equation, you would need to divide both sides of the equation by the number 98, so that the p is by itself, and so that the equation would say something like p=_.
