I hope this answer helps you
Let the price of the computer = X
Store A is selling it for 25% off, so they are selling it for 75% of the original price, so you have 0.75X
Store B is selling it for 180 less the original price, so you have X - 180
Now set both equations to equal and solve for x:
0.75x = X-180
Subtract 1X from each side:
-0.25x = -180
Divide both sides by -0.25:
x = -180 / -0.25
X = 720
The original price is $720
check:
720 x 0.25 = 180
Answer:
sqrt(54) is between 7 and 8
Step-by-step explanation:
Lets look at integers that are squared
1^2 = 1
2^2 = 2
3^2 = 9
4^2 = 16
5^2= 25
6^2 = 36
7^2 = 49
6^2 =64
54- 49 = 5 and 64 - 54 = 10
So 54 is closer to 49
so sqrt(54) is closer to the sqrt(49) = 7
sqrt(54) is between 7 and 8
Answer:
96 minutes or 1 3/5 hours
Step-by-step explanation:
To get this answer properly , we shall be converting any of the time fraction to minutes
The total time taken is 3 4/5 hours
1 hour is 60 minutes, 3 hours is 3 * 60 = 180 minutes
4/5 hours is 4/5 * 60 = 48 minutes
Total travel time is 48 + 180 = 228 minutes
Walking, he did for 2/5 hours = 2/5 * 60 = 24 minutes
Riding on a train took 1 4/5 hours; that would be 60 minutes plus 4/5 * 60 = 48 minutes ; a total time of 108 minutes
Time spent on walking and on train would be 108 minutes + 24 minutes = 132 minutes
The time spent on train would thus be 228 - 132 = 96 minutes = 60 + 36 minutes = 1 hour + 36/60 = 1 hour + 3/5 hours = 1 3/5 hours was spent on the train
