Carla bought a dress at a sale for 20% off the original price. The sale price of the dress was $68.90. Find the original price of the drees, in dollars.

Step by step explanation please.

Answers

Answer:

I think it's the second formula.

Step-by-step explanation:

Let x be the original price.

The discount rate is 20%

Sale Price is $68.90

Discount = 20% of x = 0.2x

Using the formula, Sale Price = Original Price - Discount,

Original Price - Discount is x-0.2x = 0.8x

$68.90 = 0.8x

From here on, just do the equation :) Hope this helps!

Use the 3rd one because it has fewer steps and will give you the answer

What's the difference between how we find the sale price of discounts and how we find the total price of tax, tips, and mark ups?

Answers

To find the actual discount, multiply the discount rate by the original amount 'x'. To find the sale price, subtract the actual discount from the original amount 'x' and equate this to given sale price.

Terrell arranges x roses at $3.50 each with 10 carnations at $2.25 each. He makes a bouquet of flowers that averages $3.00 per flower. Choose an equation to model the situation.

A. 3.50x + 2.25(10) = 3(x + 10)
B. 3.50x + 2.25 = 0.75x
C. 3.50x + 3 = 22.5(x + 10)
D. 3.50x + 2.50 = 0.75(x + 10)

Answers

Answer:

Step-by-step explanation:

Equation to model the situation is ( 3.5x + 22.5 ) = 3(x+10), Option A.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

Given data are :

The number of roses = x,

Price of each rose = $ 3.50,

So, the total price of roses = 3.5x dollars.

Now, the number of carnations = 10,

The cost of each carnation = $2.25,

So, the total cost of all carnations = 10 × 2.25 = $ 22.5,

Thus, the total cost of a bouquet of flowers = ( 3.5x + 22.5 ) dollars,

Also, the total numbers of flower = x + 10.

Hence, the average cost of flowers = Total cost / total flowers

average cost flowers = ( 3.5x + 22.5 ) / (x+10)

According to the question,

The average cost of flowers = $ 3.00

( 3.5x + 22.5 ) / (x+10) = 3

or,

( 3.5x + 22.5 ) = 3(x+10)

Therefore, equation to model the situation is ( 3.5x + 22.5 ) = 3(x+10).

EASY 10 POINTS QUESTION 7 PLEASEEEEEEE

Answers

Answer:

x=9

Step-by-step explanation:

-2x+9=-4x+27

first you want to get the -4x on the other side of the equal sign you do that by -4- -4 which will cancel them out and you do -2 - -4 = 2x

now you have 2x+9=27 now you do 9-9 which will cancel them out and you do 27 - 9 = 18

Now you have 2x=18 then you want to divide 2 by 2x which will cancel out the 2 and you want to divide 2 by 18 which equals 9 so you answer is x=9

{(0, 1), (0, 2), (0, 3), (0,4)}
|{(1, 1), (3, 2), (6,3), (8,4)}

Answers

Answer:

The relation {(1, 1), (3, 2), (6,3), (8,4)} is also a function ⇒ D

Step-by-step explanation:

The relation formed from a set of ordered pairs could be a function if every x-coordinate has only one y-coordinate corresponding to it

Examples:

The relation {(1, 3), (-2, 5), (1, -2)} is not a function because x = 1 has two values of y 3 and -2The relation {(2, -3), (-2, 0), (1, 5)} is a function because x = 2 has only y = -3, x = -2 has only y = 0, and x = 1 has only y = 5

Let us check all the relation to find which one is a function

∵ The relation is {(1, 6), (1, 7), (7, 8), (8, 9)}

∵ At x = 1, y = 6 and 7

→ x has two values of y

∴ The relation is not a function

∵ The relation is {(2, 3), (3, 2), (2, 4), (4, 2)}

∵ At x = 2, y = 3 and 4

→ x has two values of y

∴ The relation is not a function

∵ The relation is {(0, 1), (0, 2), (0, 3), (0,4)}

∵ At x = 0, y = 1, 2, 3, and 4

→ x has four values of y

∴ The relation is not a function

∵ The relation is {(1, 1), (3, 2), (6,3), (8,4)}

∵ At x = 1, y = 1

∵ At x = 3, y = 2

∵ At x = 6, y = 3

∵ At x = 8, y = 4

→ Every x has only one value of y

∴ The relation is a function

∴The relation {(1, 1), (3, 2), (6,3), (8,4)} is a function

Answers

This question is Incomplete

Increases in snow levels are recorded with positive numbers. Decreases in snow levels are recorded with negative numbers. After a winter storm, the depth of the snow on Cherry Street was 10 cm. But then, the snow started melting at a rate of 1/3 per hour. What was the depth of the snow on Cherry Street after 3 hours?

Answer:

9 cm

Step-by-step explanation:

The depth of snow = 10cm

Rate of melting = 1/3 cm per hour

1 hour = 1/3 cm

3 hours = x cm

Cross Multiply

= 3 hours × 1/3cm = 1 hour × x cm

x cm = 3 hours × 1/3cm/1 hour

x cm = 1 cm

Hence in 3 hours, 1 cm of snow would have melted.

Therefore, the depth of the snow on Cherry Street after 3 hours is

10cm - 1 cm

= 9 cm

A jetliner uses 3,600 gallons of fuel per hour while it is cruising, and there are 15,000 gallons of fuel in the jetliner's fuel tank when it begins to cruise.
