5x - 2 + x = 9 + 3x + 10
Combine like terms
6x - 2 = 3x + 19
Subtract 3x from each side
3x - 2 = 19
Add 2 to each side
3x = 21
Divide each side by 3
x = 7

Answer:

x = 7

Step-by-step explanation:

5x - 2 + x = 9 + 3x + 10

6x - 2 = 9 + 3x + 10

6x - 2 = 3x + 19

6x = 3x + 21

3x = 21

x = 7

A cylinder has a base with a diameter of 10.8 cm and height 15 cm into the volume of a cylinder in a cubic centimeters round you
LekaFEV [45]

Answer:

V=1,373.44\ cm^3

Step-by-step explanation:

<u><em>The correct question is</em></u>

A cylinder has a base with a diameter of 10.8 centimeters and height 15 centimeters. Enter the volume of the cylinder, in cubic centimeters. Round your answer to the nearest hundredth

we know that

The volume of a cylinder is equal to

V=\pi r^{2} h

where

r=10.8/2=5.4\ cm ----> the radius is half the diameter

h=15\ cm

assume

\pi =3.14

substitute

V=(3.14)(5.4)^{2} (15)=1,373.44\ cm^3

The distance between two villages is 0.625 km. Find the length in centimetres between the two villages on a map with a scale of
seropon [69]

Answer:

3125 cm

Step-by-step explanation:

The distance between two villages is 0.625 km. Find the length in centimetres between the two villages on a map with a scale of 1:5000.

We are given the scale of

1: 5000

This means

1 km = 5000 cm

Hence:

1 km = 5000cm

0.625 km = x cm

Cross Multiply

x cm = 0.625 × 5000 cm

x cm = 3125 cm

Therefore, the length in centimetres between the two villages is 3125cm

If AB=BA= I then write the relation between matrix A and matrix B​
butalik [34]

Answer:

If  AB = BA = I, then B is inverse of A and vice-versa.

Step-by-step explanation:

Given: AB = BA = I

To find: The relation between matrix A and B.

If AB = BA = I, then B is called the inverse matrix of A and is denoted by A^{-1}.

In that case, A is said to be invertible.

Also, if B is the inverse of A, then A is also the inverse of B.

Hence, the relation between A and B is that both are inverse of each other.
