Convert 3 1/3 into a improper fraction:
= 10/3
Then flip the other fraction around and multiply them together:
1/3 -> 3/1
(10*3)/(3*1) = 30/3 = (30/3)/(3/3) = 10/1 = 10
The answer is 10
So for 4 cans of beans for $9, each can would be $2.25 so then we multiply that by 7 so it would be $15.75 for 7 cans of beans
These solutions can be called “roots”, “zeroes”, and “x-intercepts”.
For the first one it is the fourth one 15/x
Answer:
find the inverse
exchange x for y and y for x
y=2x
then
x=2y---------> clear y
y=x/2
f−1(x)=x/2
for x=32
f−1(32)=32/2----------> 16
the answer is 16
