In this question, we're trying to find how many hours Mike had the bike for.
We know that 13 dollars as a flat rate.
We also know that they charge 13 dollars and hour.
Mike paid a total of 67 dollars for the bike.
Lets represent this as an equation:
67 = 9x + 13
x = hours the bike was rented
Solve for x:
67 = 9x + 13
Subtract 13 from both sides
54 = 9x
Divide both sides by 9
6 = x
This means that Mike rented the bike for 6 hours.
Answer:
6 hours

Answer:
answer is x=3 and y=5.... so it is (3,5)
Step-by-step explanation:
you want to combine them so y=3x-4 so subsitute y
-2x+5(3x-4)=19
-2x+15x-20=19
+20 +20
13x=39
--- ---
13 13
x=3
now subsitute 3 into x into any problem...
3(3)-4=y
9-4=y
and 9-4 is 5 so it is...
(3,5)
pls give me brainliest
Alright! So to solve these questions, you need to find out the difference. You can use ratios to solve this. For example, question #25:
A class had 30 pupils at the beginning of this school term, but now has 5 more pupils. What is the percent of increase?
The question is basically asking how much 5 is in ratio to 30. So just divide 5 (the given amount) by 30 (the total amount). The answer is 0.16, or 16%
Answer:
2.3%
Step-by-step explanation:
The formula to convert x into z distribution is
Where z is the test statistic
x is what we are looking for (in this case 37)
is the mean (in this case, it is 25)
is the standard deviation (we have 6)
<em>Plugging these into the formula, we get:</em>
Thus we can say we want 
<u>Note: </u> 
The table given is for any z where 
Thus, now we have:
0.0228 into percentage is 0.0228 * 100 = 2.28%
Rounded, we get 2.3%
Third answer choice is right.
