I don’t understand either
16x - 3 + 5x + 2 = 72
21x - 1 = 72
21x = 72+1
21x = 73
x = 73/21
x ≈ 3.48
Distance from Diego's house to the restaurant:
16x - 3 = 16 * 3.48 - 3 ≈ 52.6 miles
Distance from Anya's house to the restaurant:
5x + 2 = 5 * 3.48 + 2 ≈ 19.4 miles
52.6 ≠ 19.4 ⇒ <span>Diego was wrong.</span>
After 10 hours the temperature is shown on the graph as 30 degrees.
50 degrees - 30 degrees = 20 degrees.
The temperature dropped 20 degrees in 10 hours.
Divide the change by the time:
20 degrees / 10 hours = 2 degrees per hour.
Because the temperature dropped, the change would be negative.
The answer is D. -2 degrees per hour.
