A bike costs $650.00. Then it is marked down 35%
Vsevolod [243]

Answer:

$422.50

Step-by-step explanation:

If the bike is marked down by 35% then the final sale price will be 65% of the original price (since 100% - 35% = 65%).

Convert 65% into a decimal:  65% = 65/100 = 0.65

Therefore, 65% of $650 = 0.65 × 650 = $422.50

Describe the difference between direct variation and inverse variation.
Len [333]

When two quantities, say X and Y, are related in such a way that an increase or decrease in the value of X results in an increase in the value of Y, direct variation occurs, whereas indirect or inverse variation occurs when an increase in the value of X results in a decrease in the value of Y and vice versa.

<h3>Difference between direct variation and inverse variation:</h3>
  • To give the reader a hint, direct variation equations use the same phrase.
  • The phrase is either "directly proportional" or "directly varies."
  • The area of a square, for example, varies directly from the square of its side.
  • Direct variation occurs when two quantities, say X and Y, are related in such a way that an increase or decrease in the value of X results in an increase in the value of Y.
  • Inverse variation is a relationship between two variables in which the value of one increases while the value of the other decreases.
  • Indirect or inverse variation occurs when two quantities, say X and Y, are related in such a way that an increase in the value of X results in a decrease in the value of Y and vice versa.

Therefore, direct variation occurs when two quantities, say X and Y, are related in such a way that an increase or decrease in the value of X results in an increase in the value of Y whereas indirect or inverse variation occurs when two quantities, say X and Y, are related in such a way that an increase in the value of X results in a decrease in the value of Y and vice versa.

Solve the following equation
jok3333 [9.3K]

Answer: \frac{- 1}{11}

Step-by-step explanation:

Note: the "." symbol stands for multiplication

Given,

\frac{2x+4}{3} \\  - \frac{5x-7}{2} = 5

First we the LCM = 6,

\frac{2(2x+4)}{2.3} - \frac{3(5x-7)}{3.2}= 5

Then, we join both sides, since they have same denominator

\frac{2(2x+4) - 3(5x-7)}{6} = 5

Multiply again

\frac{4x+8 - 15x+21}{6} = 5

Add the same numbers

\frac{-11x + 29}{6} = 5

Transpose 6 to the other side

-11x + 29 = 5.6

-11x + 29 = 30

Transpose 29 to the other side

-11x = 30 -29

-11x = 1

Transpose 11 to the other side to get answer

x = \frac{-1}{11}

Hope it helps! If you have any doubts, feel free to ask
