Answer:
x>22
Step-by-step explanation:
Solve the inequality:
-3x<-14-52
-3x<-66
x>22
( You have to switch the sign because you are dividing by a minus)
It helps to think of a simpler problem. Let's say mpg is 20 and 10% higher on a smooth road.
How many miles will you get with one gallon on a regular road?
How many more miles will you get on a smooth road? 10% more, right? How much is that?
OK - so you've now solved a simpler problem. Use the exact some process to solve your, more complicated, problem.
Answer:
n = 3
e = 5
Step-by-step explanation:
10n + 3e = 45
2n + 5e = 31
10n + 3e = 45
10n + 25e = 155
o + 22e = 110
e = 5
to fix 5 into the first equation
10n + 3(5) = 45
10n + 15 = 45
10n = 45 -15
10n = 30
n = 3
