First, you set up a proportion : quilts / yards = 9 / 18 = 10 / x
Then, you solve for x.
x = 20
Hope this helps! If you have any further concerns, feel free to let me know!
Answer:
c
Step-by-step explanation:
i think
Find what the 5 is and times the f with x
(7^x)^4 is equal to 7^(4x).
7^2 * 7^3 is equal to 7^(2+3) which is equal to 7^5.
7^5 / 7^(3x) is equal to 7^(5 - 3x).
you wind up with 7^(4x) is equal to 7^(5 - 3x)
this is true if and only if 4x = 5 - 3x.
