Answer:
n= -12
Step-by-step explanation:
- 2n/3 + 7=15 Subtract 7 from both sides and move all terms containing
-7 = -7 n to the right
- 2n/3 = 8 multiply both sides of equation by - 3/2
-3/2 x (-2n/3) = -3/2 x 8
n= -3/2 x 8 cancel the common factor of 3
n= -12
Answer:
Because the cost price of 30 pens = Rs. 150
So, the cost price of 1 pen = 150/30 =5
so, the cost price of 20 pens =
Rs. 5 x 20 = 100
Cp is Rs. 100
Sp is Rs. 140
So, profit = 140-100 = Rs. 40
Profit % = (Profit x 100)xCp
=(40 x 100)/100
= 4000/100
= 40% profit
Step-by-step explanation:
The only way I can think of is filling the 3-quart dumping it into the 5-quart. Fill the 3-quart again and then use it to fill the 5-quart the rest of the way. That process should leave you with 1-quart of water in the 3-quart container.
The number of kilometers she will have left to run to finish the race is 0.9 km.
<u>Given the following data:</u>
- Speed =

To determine the number of kilometers she will have left to run to finish the race:
First of all, we would calculate the distance she has covered by using this formula;

Distance = 12.6 meters.
<u>For the </u><u>distance left</u><u>:</u>

Distance left = 0.9 km.
