Solve the inequality and show your solution on a number line: 0.2x−2<7−8x

Allisa [31]

Answer:

$x< \frac{45}{41}$ or $x< 1.098$

The graph in the attached figure

Step-by-step explanation:

we have

$0.2x-2 < 7-8x$

Solve for x

Adds 2 both sides

$0.2x-2+2 < 7-8x+2$

$0.2x < 9-8x$

Adds 8x both sides

$0.2x+8x < 9-8x+8x$

$8.2x < 9$

Divide by 8.2 both sides

$x < 9/8.2$

Remember that

$8.2=82/10$

substitute

$x < 9/(82/10)$

$x< \frac{90}{82}$

Simplify

$x< \frac{45}{41}$ or $x< 1.098$

The solution is the interval ------> (-∞, 45/41)

All real numbers less than 45/41

In a number line , the solution is the shaded area at left of x=45/41 (open circle)

Find the value of x. The diagram is not to scale.

Lubov Fominskaja [6]

Answer:

x = 13

Step-by-step explanation:

110° is the vertically opposite angle of one of the interior angles of the given triangle.

Therefore,

$x \degree + 57 \degree + 110 \degree = 180 \degree \\ \\x \degree + 167 \degree = 180 \degree \\ \\ x \degree = 180 \degree -167 \degree \\ \\ x \degree = 13 \degree \\ \\ x = 13$

WILL GIVE BRAINLIEST! Match the equations that are the same

wolverine [178]

Answer:

1. 1/x = 8

Answer = 8x-1

2. 8x+1=3

Answer ; x=1/4

3. 7= 14/X

Answer ; x = 2

4.1/2x^2 = 2

Answer ;x=2

Step-by-step explanation:

$\frac{1}{x} =8 \\8x = 1\\\\\\8x+1=3\\Collect -like- terms \\8x =3-1\\8x = 2\\Divide -both -sides- by ;8\\\frac{8x}{8} =\frac{2}{8} \\x = 1/4\\\\\\7= \frac{14}{x} \\Cross -multiply\\7x =14\\Divide-both-sides-by-7\\x = 2\\\\\\\frac{1}{2} x^{2} =2\\\frac{x^{2} }{2} =2\\Cross-multiply\\x^{2} =4\\Squre-root -both-sides\\\sqrt{x^2}=\sqrt{4} \\x = 2\\$
