find the number of miles per 1 liter:
247 kilometers / 19 liters = 13 kilometers per liter.
Divide how may kilometers they want to go by kilometers per liter:
429 kilometers / 13 kilometers per liter = 33 liters are needed.
N=4.5 In the picture are the steps you should follow to solve for n.
Answer:
-13
Step-by-step explanation:
(7−15−3+5−7)⋅1
Subtract 15 from 7 to get −8.
(−8−3+5−7)×1
Subtract 3 from −8 to get −11.
(−11+5−7)×1
Add −11 and 5 to get −6.
(−6−7)×1
Subtract 7 from −6 to get −13.
−13
Step-by-step explanation:
Total books = 368.
Sociology books = 92.
Psychology books = 3 times sociology books
= 3 x 92 = 276
Total = 276 + 92 = 368
