Solve the simultaneous equation 5x+3y=23 2x+4y=12
uranmaximum [27]

() = Fraction

Answer:

1. x= −(3 /5 y)+ (23 /5)

2. x=−2y+6

Step-by-step explanation:

Let's solve for x.

5x+3y=23

Step 1: Add -3y to both sides.

5x+3y+−3y=23+−3y

5x=−3y+23

Step 2: Divide both sides by 5.

5x /5 = −((3y+23) /5)

x= −(3 /5 y)+ (23 /5)

------------------------------------------------

Let's solve for x.

2x+4y=12

Step 1: Add -4y to both sides.

2x+4y+−4y=12+−4y

2x=−4y+12

Step 2: Divide both sides by 2.

(2x /2 )= −((4y+12) /2)

x=−2y+6

Hope it helped!

the water pipe has a radius of 5 cm and a height of 7 cm. What volume of water does it take to fill the pipe
kvv77 [185]
When you're looking for the volume of a cylinder, you have to use the equation V=  \pi r^{2} h
And this V is equal to volume, R is equal to radius, and H is equal to height.
In this case, you've got to find what r²is. To do this, square 5. 5x5= 25. 
You've then got to substitute this into the equation, along side H, which is equal to 7, and this gives you V=π*25*7, you've then got to multiply these all together (using π as 3.142) this gives you 549.85cm³
Therefore, you need 549.85cm³ of water to fill the pipe.
Hope this helps :)
