Answer:
x = 9/10
Step-by-step explanation:
This problem features a ratio: 4x/3 = 6/5
By cross multiplying you get that 4x*5 = 3*6 or 20x = 18. By dividing both sides by 20, you get that x = 18/20, and when simplified, 9/10.
4 x² + 6 = 40
4 x² + 6 - 6 = 40 - 6
4 x² = 34
x² = 34 : 4
x² = 8.5
x = √ (8.5)
x 1 = 2.9154759 ≈ 2.92 ( to the nearest hundredth )
x 2 ≈ - 2.92
Answer:The solutions are approximately 2.92 and - 2.92.

This is very simple. She wants to split evenly to her 16 friends. All you have to do is 258.8 divided by 16. The answer is 16.175 gallons of vegetable soup to each friend. You can check this by using a calculator. I hope this helps!
The total distance is D=d1+d2+d3
d1=30x0.5
d2=50x1
d3=30x0.5
D=d1+d2+d3=80miles
