Explain how to isolate the variable in the equation -2/3+7=15
Tasya [4]

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

A shopkeeper bought 30 pens for 150 and sold 20 of them for 140. Find his profit or loss percentage
Gre4nikov [31]

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

If u have only a 3-quart pitcher and 5-quart pitcher how can you measure exactly 1 quart
liraira [26]
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.

Kay is running a 13.5 km race. If she runs at a rate of 8 2/5 km/he for 1.5 hours, how many kilometers will she have left to run
Monica [59]

The number of kilometers she will have left to run to finish the race is 0.9 km.

<u>Given the following data:</u>

  • Total distance = 13.5 km
  • Speed = 8\frac{2}{5} \;km/hr
  • Time = 1.5 hours

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 = speed \times time\\\\Distance = 8\frac{2}{5} \times 1.5\\\\Distance = \frac{42}{5} \times \frac{3}{2} \\\\Distance = \frac{63}{5}

Distance = 12.6 meters.

<u>For the </u><u>distance left</u><u>:</u>

Distance\;left = Total\;distance - Distance\;covered\\\\Distance\;left =13.5 -12.6

Distance left = 0.9 km.
