B is true; pi= ~3.14. 3+4 is equal to 7, so because pi is greater than 3, pi+4>7
Assume the number of trucks is x
number of cars is 5x
5x+x=30
6x=30
x=5
Julia saw 5 trucks
The answer for " J " would be 228

Answer:
r = 
Step-by-step explanation:
12 - 
= 5
6 × 12 × r × 6 - = 5 × 6
72r - r = 30
71r = 30
r = 30 ÷ 71
r =
Loretta:
Average driving speed = 55 mph
Time = 4 hours
Distance traveled = 55*4 = 220 miles
Dad:
Average driving speed = 65 mph
Let x = hours driven
Distance traveled = 65x miles
The length of the trip is 610 miles, therefore
65x + 220 = 610
65x = 390
x = 6 hours
Answer: Loretta's dad drove for 6 hours.
