<h3>Answer:  $225</h3>

=============================================

Explanation:

x = original price

If she saves 20%, then she still pays the remaining 80% which then converts to the decimal form 0.80

The expression 0.80x represents the new price, or sale price, of the dress. We're told this price is $180

Equate the two expressions and solve for x

0.80x = 180

x = 180/0.80

x = 225

The original price is $225

------------------------

Checking the answer:

20% of 225 = 0.20*225 = 45

She saves $45

225 - 45 = 180

This confirms the answer.

Find the value of x that verifies that l ⊥ m.
Genrish500 [490]

Answer:

X= 12

Step-by-step explanation:

Simplifying

4x + -2 = 46

Reorder the terms:

-2 + 4x = 46

Solving

-2 + 4x = 46

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2' to each side of the equation.

-2 + 2 + 4x = 46 + 2

Combine like terms: -2 + 2 = 0

0 + 4x = 46 + 2

4x = 46 + 2

Combine like terms: 46 + 2 = 48

4x = 48

Divide each side by '4'.

x = 12

Simplifying

x = 12

Need help! Law of cosines...find b round to the nearest tenth please
dusya [7]
ANSWER

B = 27.8 \degree

EXPLANATION

The law of cosine is given by the formula:

{b}^{2} = {a}^{2} + {c}^{2} - 2bc \cos(B)

From the diagram,

a=17, b=8, c=16

We substitute the given values into the formula to obtain:

{8}^{2} = {17}^{2} + {16}^{2} - 2(17)(16)\cos(B)

64 = 289+ 256- 544\cos(B)


64 = 545- 544\cos(B)


64 - 545 = - 544\cos(B)

- 481 = - 544\cos(B)

\frac{ - 481}{ - 544} = \cos(B)

cos(B) = 0.88419

B = \cos ^{ - 1} (0.88419)

B = 27.8 \degree
