Explanation 1:

Her guinea pig is

25 cm long.

25 cm = 250 mm

Her fish is 40 mm long, so her guinea pig is longer than her fish by

25 cm − 40 mm = 250 mm − 40 mm = 210 mm= 21 cm

Explanation 2:

First, lets convert the length of Naomi's guinea pig from cm to mm.

1 cm=10 mm

We can multiply each side of the equation by 25 to obtain the length of the guinea pig in mm.

25 × 1 cm = 25 × 10 mm

25 cm = 250 mm

Because we have a length of the guinea pig and the fish in a common metric we can subtract the two values: 250 mm − 40 mm = 210 mm The guinea pig is 210 millimeters longer than the fish. Or, if we want to convert this to centimeters we can divide by 10: 210 millimeters 10 = 21 centimeters

Hope this helps have a good day/night!

PLZ EXPLAIN , I WANT TO KNOW HOW TO DO

Make sure you know the formula pertaining to the question.

1. c=2(pi)(r)
2. c=2(pi)(d)

r= radius
d= diameter
c= sircumference

So we are given that the circumference of a circle is 12.3pi and the radius is unknown.

So let's plug in the known values

**we use the formula with the radius, becuase we are looking for the radius.

c=2(pi)(r)
12.3(pi)=2(pi)(r)

divide each side by pi

12.3=2(r)

divide each side by 2

r=6.15 in.

Solve the 3x3 system shown below. Enter the values of x, y, and z.

slamgirl [31]

Answer:

x = 1

y = -1

z = 2

Step-by-step explanation:

You have the following system of equations:

$x+2y-z=-3\ \ \ \ \ (1)\\\\2x-y+z=5\ \ \ \ \ \ (2)\\\\x-y+z=4\ \ \ \ \ (3)$

First, you can subtract euqation (3) to equation (1):

x + 2y - z = -3

-x +y -z = - 4

0 3y -2z = -7 (4)

Next, you can multiply equation (3) by 2 and subtract it to equation (2):

2[ x -y + z = 4]

-2x +y -z = -5

0 -y + z= 3 (5)

You multiply equation (5) by 2 and sum (5) with (4):

2[ -y + z = 3]

3y -2z= -7

y + 0 = -1

Then y = -1

Next, you replace y=-1 in (5) to obtain z:

-(-1) + z = 3

z = 2

Finally, you can replace z and y in the equation (3) to obtain x:

x - (-1) + (2) = 4

x = 1
