Answer: 9 and 4
Step-by-step explanation:
A coefficient is a number that is before a variable and in this case it’s 9 and 4 that are before the variables x and y.
Just slot the value of x (which is 20), everywhere you see the letter x.
Similarly, slot the value of y (which is 17), everywhere you see the letter y.
So forth,
x + 8 - y
becomes
20 + 8 - 17
which evaluates to 11.
First, change the mixed fraction into improper fraction
1 1/7 = 7/7 + 1/7 = 8/7
(4/7)/(8/7)
To solve, flip the second fraction, and change the division into multiplication
(4/7)/(8/7) = (4/7) x (7/8)
Multiply, and simplify
(4/7) x (7/8) = 28/56, or 1/2
1/2 is your answer
hope this helps
