WILL GIVE BRAINLIEST. If x+y=3 and 3x+5y=13, then x-y is equal to?

Alex17521 [72]

Answer:

(1,2)

y=2

x=1

Step-by-step explanation:

x+y=3

3x+5y=13

solve the equation

x=3-y

3x+5y=13

substitute the value of x into an equation

3(3-y)+5y=13

distribute

9-3y+5y=13

add -3y to 5y

9+2y=13

subtract 9 from both sides

2y=4

divide both sides by 2

y=2

substitute the value of y into an equation

x=3-2

subtract 3 to 2

x=1

--------

(1,2)

A cylinder and a cone have the same base and height. The cylinder can hold about 4,712 Centimeters cubed of sand. Jared says tha

klasskru [66]

Answer:

C. Jared is not correct because the cone and the cylinder have the same base and height so the cone holds 4,712/3≈1,571 centimeters cubed of sand.

Step-by-step explanation:

We have a cone and a cylinder with the same base and height.

We can express the volume of the cylinder as:

$V_{cyl}=\pi r^2H$

being r the radius and H the height.

The volume of the cone can be written as:

$V_{con}=\dfrac{\pi}{3}r^2H=\dfrac{V_{cyl}}{3}$

As they have the same base and height, we know that the volume of the cylinder is 3 times the volume of the cone.

If the volume of the cylinder is 4,712 cm^3, then the volume of the cone is:

$V_{con}=\dfrac{V_{cyl}}{3}=\dfrac{4,712}{3}\approx1571$
