Three times a number is the same as five more than twice the number

2 answers:

7 0

3x (three times a number) = (is the same as) 5 + (five more than) 2x (twice the number)

or, 3x = 5+2x
then subtract 2x from both sides: x = 5

Which should make sense, three times 5 is 15. 5 plus two times 5 is also 15.

Ok so first lets make the equation
3x=5+2x
we subtract 2 on each side
x=5

Find the midpoint of (-7,-2) AND (1,7)

Gala2k [10]

Answer:

(-3 ,2.5)

Step-by-step explanation:

midpoint formula is

x1+x2 y1+y2

(___ , _____ )

2 2

(-7,-2) -7 is x1 i.e the first x point and -2 is y1 1st y point

(1,7) 1 is x2 i.e the second x point and 7 is y2 the second y point

now we use input the numbers to the formula

-7+1 -2+7

(____ , --------)

2 2

we the signs are different you subtract and use sign of greater number

-6 5

__ , ___

2 2

Now you divide

and here is the ordered pair for midpoint.

(-3 ,2.5)

Trey had a cylindrical can with a radius of 4 inches and a height of 12 inches that was completely full of beet juice. He poured

Arisa [49]

Answer:

$8\ glasses\ of\ juice$

Step-by-step explanation:

step 1

Find the volume of the cylindrical can

The volume of the cylinder is equal to

$V=\pi r^{2}h$

we have

$r=4\ in\\ h=12\ in$

substitute the values

$V=\pi (4)^{2}(12)=192\pi\ in^{3}$

step 2

Find the volume of the cylindrical glasses

The volume of the cylinder is equal to

$V=\pi r^{2}h$

we have

$r=2\ in\\ h=8\ in$

substitute the values

$V=\pi (2)^{2}(8)=32\pi\ in^{3}$

Find the volume of 3/4 of the glass

$32\pi (\frac{3}{4})=24\pi\ in^{3}$

step 3

Divide the total volume of cylindrical can by the 3/4 volume of the glass

$192\pi\ in^{3}/24\pi\ in^{3}=8\ glasses\ of\ juice$
