on edgen, the answer is B) 30sqrt3
Answer:
The inequality representation is : x + y ≥ $400
Step-by-step explanation:
- Inequality is the comparison and boundary for two non equal values. So inequality compares the non equal values.
- As the owner wants to make $400 and sets boundary that;
Least amount to make = $400
Highest amount to make= infinite
- This introduces relation in inequality as $400 or greater than $400.
- The money made is counted combine from child tickets and adult tickets. If x is the made made through child tickets and y is from the adult then,
x + y ≥ $400
Answer:
Sale Price:
50x-20%=10
50-10= 40
Total Price:
40x-8%=3.20
40+3.20= 43.20
Step-by-step explanation: If you encounter more problems like this, use the x and - method! Its easier to understand and a shorter method :)
<span>7/4=1.75
23/12=1.92
11/6=1.83
5/3=1.67
1 5/6= 11/2=0.5
17/42=0.40
16/21=0.76
5/7=0.71
so least to greatest: 17/42, 1 5/6, 5/7, 16/21, 5/3, 7/4, 11/6, 23/12</span><span>

Let x and (442-x) represent the distance of the trains traveled. X/90 mph=442-x/80 mph
Cross multiply 80×x =90(442-x)
80x=90×442-90x
170x=90×442
X= 90×442/170
X=234, distance traveled by train going 90mph
234mi/90mph = 2.6 hr, time it takes for the two trains tok meet.
Checking your answer:
90×2.6+80×2.6=234mi+208mi = 442mi
