Answer:

3) y = 2

Step-by-step explanation:

Step : 1

given 2 y-1 =3

Adding '1 ' on both sides, we get

2 y -1 +1 = 3+1

2 y = 4

dividing by '2' on both sides, we get

$\frac{2y}{2} = \frac{4}{2}$

cancelling '2' on both sides, we get

y = 2

Evaluate the determinant for the following matrix [144] [522] [155]

WARRIOR [948]

Matrix :

1    4    4

5 2    2

1    5    5

=> Determinant =

1 * (2*5 - 2*5) - 4 * (5*5 - 1*2) + 4 * ( 5*5 - 2*1)

= 1*(10 - 10) - 4*(25 - 2) + 4*(25 -2) = 1*0 + 4* 23 + 4*(25 - 2) = 0 - 4*23 + 4*23 = 0

1/2(4-+6x)=1/3x+2/3(x+9)

KonstantinChe [14]

Answer:

The value of x for the expression is 2

Step-by-step explanation:

Given algebraic expression as :

$\frac{1}{2}$ (4 + 6 x ) = $\frac{1}{3}$ x + $\frac{2}{3}$ ( x + 9 )

Now, solving the given expression

Or, $\frac{1}{2}$ × 4 + $\frac{1}{2}$ × 6 x = $\frac{1}{3}$ x + $\frac{2}{3}$ x + $\frac{2}{3}$ × 9

Or, $\frac{4}{2}$ + $\frac{6}{2}$ × x = $\frac{1}{3}$ x + $\frac{2}{3}$ x + $\frac{18}{3}$

or, 2 + 3 × x = $\frac{x}{3}$ + $\frac{2 x}{3}$ + 6

or, 2 + 3 × x = $\frac{2 x + x}{3}$ + 6

or, 2 + 3 × x = $\frac{3 x}{3}$ + 6

Or, 2 + 3 × x = x + 6

or, 3 x - x = 6 - 2

Or, 2 x = 4

∴ x = $\frac{4}{2}$

I.e x = 2

Hence The value of x for the expression is 2 Answer
