<u>Answer</u>
F(a+2) = (3a+11)/(a+2)
<u>Explanation</u>
F(x) = (3x + 5)/x
If you are to find F(a+2), you replace x with (a+2)
F(a+2) = (3(a+2)+5))/(a+2)
= (3a+6+5)/(a+2)
=(3a+11)/(a+2)
To solve this problem, we can make a proportion.
Since Kiara's money has a ratio of 9:7 in comparison to Tyler's, we can make the proportion as follows:
9/7=126/x, where x is Tyler's money. This can be simplified to 9=882/x, or 9x=882. Then, divide by 9 to find x, which results in x=98.
Now we know that Tyler has $98, so we just need to add 126 to 98 and get $224 all together.
Hope this helps!
If you mean the system between the two then comes (x;y)=(5;3) otherwise if solved individually they are enough to make the common denominator
