Solve for x 12x/5 a.x=-71/2 b. x=71/2 c. x= 43 1/5

babunello [35]

Answer:

x = - 12 6/7

Step-by-step explanation:

x - 12x/5= 18

Get a common denominator on the left

5/5 x -12/5x = 18

Subtract

-7/5 x = 18

Multiply each side by -5/7 to isolate x

-5/7 *-7/5 x = -5/7 *18

x = -5*18/7

x = -90/7

Changing this to a mixed number

7 goes into 90 1 2 times with 6 left over

x = - 12 6/7

What are the factors of the square root of 329

Andru [333]

Answer: $x=-\dfrac{3}{2}, 7$

Step-by-step explanation:

$2x^2-10x-26=x-5$

$2x^2-10x-26-x+5=0$ Move all terms to one side

$2x^2-11x-21=0$ Simplify $2{x}^{2}-10x-26-x+5$

$2x^2+3x-14x-21=0$ Split the second term

$x(2x+3)-7(2x+3)=0$ Factor out common terms in the first two terms, then in the last two terms.

$(2x+3)(x-7)=0$ Factor out the common term $2x+3$

$x=-\dfrac{3}{2}, 7$
