4 1/2 = 9/2
1 5/7 = 12/7
9/2 / 12/7 = 21/8 = 2.625
Option #1 (and the fastest):
Multiply both sides by 3 to cancel the “divided by 3” on the left side where z is.
z/3 • 3 = 5/4 •3
z = 15/4
Option #2: Cross multiply and then solve for z:
z/3 = 5/4 -> 4z=15
Then divide by 4.
4z/4 = 15/4
z = 15/4
Mainly all you do is subtract , and it'll give you the right estimate
Slope: 0
Y-intercept: 5
The answer is 0,5
I hope this helps.
The answer would be $78..
