Mathematics
1 answer:
larisa86 [58]4 years ago
5 0

Answer:

ne solution was found :

                  r = -2

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :  

               8*(x+6)-10+r-(3*(x+12)+5*x)=0  

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 (((8•(x+6))-10)+r)-(3•(x+12)+5x)  = 0  

Step  2  :

Equation at the end of step  2  :

 ((8 • (x + 6) -  10) +  r) -  (8x + 36)  = 0  

Step  3  :

Equation at the end of step  3  :

 r + 2  = 0  

Step  4  :

Solving a Single Variable Equation :

4.1      Solve  :    r+2 = 0  

Subtract  2  from both sides of the equation :  

                     r = -2  

One solution was found :

                  r = -2

8 Darpan runs a distance of 12 km and then cycles a distance of 26 km. His running speed is x km/h and his cycling speed is 10 k
Sonja [21]

The equation in terms of x, for the total time he takes in hours would be 2.48 = 12/x  + 26/10x

<h3>What is speed?</h3>

Speed can be calculated as the ratio of distance traveled to the time taken

Darpan runs a distance of 12 km and then cycles a distance of 26 km.

Total distance = 12 + 26 = 38km

The running speed is x km/h

A = x

The cycling speed is 10 km/h faster than his running speed

B = 10x

He takes a total time of 2 hours and 48 minutes.

So, the total time he takes

Time = Distance x speed

2.48 = 12/x  + 26/10x

10x(2.48) = 120 + 26

24.8x = 146

x = 5.8

a winery has a vat with two pipes leading to it. the inlet pipe can fill the vat 7 hours, while the outlet pipe can empty it in
raketka [301]
Lets say, for ease, that the vat can hold a total of 70 gallons (or whatever you would like to use.) Use whatever number you want, I just picked this because it gives us a lot of clean numbers. 

Now, if the inlet can fill it in 7 hours, that means that it is adding 10 gallons per hour. (70 gal/7 hours = 10 gal/hr)

For the outlet, use the same process, and you find that it drains the vat at 7 gallons per hour. 

So, if you subtract the outlet from the inlet, you get 10 - 7 = 3 gallons per hour added. 

Now just divide the size of the vat by that number, and you find your answer. 

70 gallons / 3 gallons per hour = 23 1/3 hours.

A coordinate plane. Which expression could help you find the distance between (10, 4) and (–6, 4)?
nirvana33 [79]

Answer:

d=16

Step-by-step explanation:

d: distance (10,4),(-6,4)

d=√(x2-x1)^2+(y2-y1)^2

d=√(-6-10)^2+(4-4)^2

d=√16^2

d=16
