2x + 4 because she is playing 2 times as much as trent which is where the 2x come in and also 4 more hours than kailey which is the +4
I didn't state this earlier, but you should find the common denominator so in this case it is 10.
1/2=5/10, 9/10 stays the same, and 4/5=8/10.
Now you add them up.
5/10 + 9/10 + 8/10 = 22/10
22/10 = 2 2/10
2 2/10 = 2 1/5
Answer: A. 2 1/5
So exg
input is the numbers that will work so normally the range is all real numbers
make sure that you don't have any numbers that will make impossiblities exg
is the function is f(x)=3/x you can't use 0 for x because 3/0 is undifined and is impossible so
input is the numbers you put in
out put is what numbesr you get from the input exg
if function =f(x)+x+3 then
if input=3,5,6 then output is
(replaace 3,5,6 for x and solve)
output is 6,8,9
The answer is the first one
