The sale price of an item is $160 after a 20% discount. What was the original price of the item?

Answers

Answer:

200 sorry read that wrong

Step-by-step explanation:

Answer:

The original price of the item is $200.

Step-by-step explanation:

Let the original price be 'x'.

The sale price of an item is $160 after a 20% discount.

i.e. original price - 20% of original price = $160

x-20/100x=160

x-0.2x=160

0.8x=160

x=160/0.8

x=200

Therefore, the original price of the item is $200.

The volume V of a rectangular prism with length l, width w, and height h is v equals l times w times h. What is the width of a rectangular prism with volume 450 cubic inches, length 20 inches, and height 7.5 inches?

Answers

Answer:

The answer is 3 inch

Step-by-step explanation:

To start off, the equation you want to use the formula V=whl

Next, you simply plug in the values you already know, so you have 450=w*20*7.5

After you do that you multiply 20 times 7.5 to get which is 150, which leaves you with 450= w *150 to solve for w, you need to isolate it. To do that you divide 450 by 150. You are left with the answer of 3.

450=w•20•7.5
^
450= w150
——- ———
150. 150

x=0.025253

The value of x from the given ratios 2 2/7 :(0.6x)= 4/21 :0.25 will be 5.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

[tex]2 \frac{2}{7}[/tex] :(0.6x) = 4/21 :0.25

Therefore, solve the mixed fraction, we get

16/7 :(0.6x) = 4/21 :0.25

Step 1: Simplify both sides of the equation.

16/7 :(0.6x) = 4/21 :0.25

(16/7) / (0.6x) = (4/21 ) / (0.25 )

Step 2: Divide both sides

(16/7) / (0.6x) = (4/21 ) / (0.25 )

Cross multiply:

(16/7) x (0.25 )= (4/21 ) x (0.6x)

4/7 = 2.4x /21

84 = 16.8x

Divide both sides by 16.8:

3c + 1 = 10 Need help with this I have so many assignments to do Help me Please and Thank you!

Answers

Answer:

c = 3

Step-by-step explanation:

You are solving for the variable, c. Isolate the variable c. Note the equal sign, what you do to one side, you do to the other.

Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

~

First, subtract 1 from both sides of the equation:

3c + 1 = 10

3c + 1 (-1) = 10 (-1)

3c = 10 - 1

3c = 9

Next, divide 3 from both sides of the equation:

(3c)/3 = (9)/3

c = 9/3

c = 3

c = 3 is your answer.

~

c = 3 because 3 x 3 is 9 + 1 is 10

Please answer! Im giving half of all my points!!

Answers

Answer:

first side = 33

second side = 20

third side = 37

Step-by-step explanation:

first side = 2x-7

second side = x

third side = (2x-7)+4

(2x - 7) + x + (2x - 7) + 4 = 90

5x - 14 + 4 = 90

5x - 10 = 90

5x = 100

x = 20

first side:

40 - 7 = 33

second side: 20

third side:

(2(20) - 7) + 4

(40 - 7) + 4

33 + 4 = 37
