125% because sixteen is equal to a whole which is equal to one-hundered and one fourth of sixteen is four and sixteen plus four is twenty. one fourth of one-hundered is twenty-five so you add the twenty-five to the one-hundered and you get 125%
Answer:
A
Step-by-step explanation:
To find an inverse function you switch f(x) and x, and solve for f(x) (in this case you also rename it to g(x) )
inverse of y=(x-4)/5 is
5x = x -4
x = 5x + 4 so A works
z is directly proportional to x: z = kx.
If z is directly proportional to x and inversely proportional to y, then z = Kx/y.
When x= 6 and y = 6, z is 12. Find the constant of proportionality, K:
12 = K(6/6), or K = 12
Then, in general, z = 12x/y.
What is z when x=13 and y=10? z = 12(13)/(10) = 15.6 (answer)
-4 if you have any more equations like this you can use this app called photomath
The correct answer is A) x=3
What this picture demonstrates is 3 x’s on the left side and 9 ones on the right. So it says 3x=9. If you were to divide by 3, or multiply by 1/2, you’d have x=3.
Another way to think of it is by redrawing the picture. Each ‘x’ would get three “1’s” thus x=3
