Answer:
speed of westbound car= 50 miles/hour
speed of eastbound car = 50 + 4 = 54 miles/hour
Step-by-step explanation:
Let the speed of westbound car = x
According to given scenario, speed of eastbound car will be = x + 4
Now
Distance given = 208 miles
Total time = 2 hours
As both cars pass each other so by using the formula beloe:
Speed of both cars = Distance / Time
x + (x + 4) = 208 / 2
2x +4 = 104
Subtracting 4 from both sides
2x = 104 - 4
2x = 100
Dividing both sides by 2
x (speed of westbound car)= 50 miles/hour
x + 4 (speed of eastbound car) = 50 + 4 = 54 miles/hour

Answer:y=4 x=3
Step-by-step explanation:9(-9+3y)-4y=11
-81+27y-4y=11 23y=92 y=4 x=3
Answer:
<h2>y = 3x - 4</h2><h2 />
Step-by-step explanation:
3x - y = 4 ⇔ 3x - y - 4 = 0 ⇔ 3x - 4 = y ⇔ y = 3x - 4
