The same reason 4 dimes and 4 pennies aren't equal.
To put it into decimal terms, 4/10 is 0.40 (or forty cents), whereas 4/100 is 0.04 (or four cents)
Answer: 42/9
Step-by-step explanation: 7/9 x 6/1 = 42/9
To find the x int, sub in 0 for y and solve for x
5x - 3y = 30
5x - 3(0) = 30
5x = 30
x = 30/5
x = 6....so the x int is (6,0)
to find the y int, sub in 0 for x and solve for y
5x - 3y = 30
5(0) - 3y = 30
-3y = 30
y = 30/-3
y = -10...so ur y int is (0,-10)
