Answer:

Answer:
750 km
Step-by-step explanation:
50% of 1500 km

Answer:
exact form: 433/42
decimal form: 10.309
mixed number form: 10 13/42
Step-by-step explanation:
4x + 3y = 65
X + y = 18
When you use elimination, multiply the second equation by -3
4x + 3y = 65
-3X -3y = -54
X = 11
X+y = 18
11 + y = 18
Y = 7
