If 1 cm = 500 miles......then 2.2 cm = (2.2 * 500) = 1100 miles <==
To find the y-intercept, let x = 0.
0 - 3y = -6
-3y = -6
y = 2
The y-intercept of the equation is the point (0, 2).
33 rounded to the nearest 10 is 30, 89 rounded to the nearest 10 is 90. So 90+30 is 120. Let me know if I am right!
Answer:
C.Infinitely many solutions
I solved by substitution

Infinitely many solutions
56000 is the answer because 10 to the third power is 1000. and 1000×56 is 56000
