Ind the value of x which satisfies the equation 2x - (4 - x) = 5 - X​

x = 9/4 = 2.25

Step-by-step explanation:

First thing to do when solving this equation would be to expand the brackets.

Because the sign in front of the brackets it a negative/minus, it means that we have to reverse the signs of both numbers inside (i.e. positive numbers become negative and vice versa):

Next, we can move all the x-terms to one side and the constants to the other so we can solve for a numerical constant value of x.

To do this we will first combine like terms (x's and x's etc.), and then subtract or add that value from both sides. This allows us to move terms to the other side without changing the equation (both sides are still equal):

We can also test this answer by substituting it back into the original equation for 'x':

In which case the equation checks out, meaning we got the correct answer.

Hope this helped!

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
