Answer:
(0°F − 32) × 5/9 = -17.78°C
= -17.8°C
3x - 2 = 7
3x = 7 + 2
3x = 9 (divide both sides by 3 to get x)
3x/3 = 9/3
x = 3
1.4 decameters. Hope this helped!
Answer:
26km
Step-by-step explanation:
The train can travel 78km per hour or per 60 min
78 = 60
x = 20
Cross multiply:
(78)(20) = 60x
1560 = 60x
x = 26
Thus the train travels 26km in 20 min
Answer:
2.5°C
Step-by-step explanation:
You can find the average by adding together all of the numbers and dividing the sum by the amount of numbers. In this case the numbers are 10.4, 0, -2, -2.1, and 6.2. When you add these numbers together, you get 12.5. Since there are 5 numbers, you divide 12.5 by 5 and you get...
2.5°C
