X-26 over -9= 5 please help quick

nexus9112 [7]

Answer:

x = -19

Step-by-step explanation:

$\frac{x-26}{-9}=5$

Multiply both sides of the equation by -9.

$\frac{\left(x-26\right)\left(-9\right)}{-9}=5\left(-9\right)$

x - 26 = -45

Add 26 to both sides.

x - 26 + 26 = -45 + 26

x = -19

Solve x2 + 1/2x +1/16=4/9

kolezko [41]

Answer:

x = 0.417 or x = -0.917

Step-by-step explanation:

We are given the following expression and we are to solve it for the variable x:

$x ^2 + \frac { 1 } { 2 } x + \frac { 1 } { 1 6 } = \frac { 4 } { 9 }$

We will find the least common multiple of 2. 6 and 9:

$x^2 \times 144 +\frac{1}{2}x \times 144 +\frac{1}{16} \times 144 = \frac{4}{9} \times 144$

Simplifying it to get:

$144x^2+72x+9=64$

$144x^2+72x+9-64=0$

$144x^2+72x-55=0$

Using the quadratic formula to solve for x:

$x=\frac{-b \pm\sqrt{b^2-4ac} }{2a}$

$x=\frac{-72 \pm\sqrt{72^2-4(144)(-55)} }{2a}$

$x=\frac{5}{12}$ or $0.417$

$x=-\frac{11}{12}$ or $-0.917$

Refer to the triangle below what is the volume of X. 45° 60°

RUDIKE [14]

Answer:

x = 75

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the given angles from 180 for x

x = 180° - (60 + 45)° = 180 - 105° = 75°
