Five more than the quotient of a number and 3 equals 2.

MakcuM [25]

Answer:

$\large\boxed{\dfrac{n}{3}+5=2\ or\ n:3+5=2}$

Step-by-step explanation:

$\dfrac{n}{3}+5=2\\\\\dfrac{n}{3}-\text{the quotient of a number}\ n\ \text{ and 3}\\\\...+5-\text{five more than}$

If you want a solution:

$\dfrac{n}{3}+5=2$ <em>subtract 5 from both sides</em>

$\dfrac{n}{3}+5-5=2-5$

$\dfrac{n}{3}=-3$ <em>multiply both sides by 3</em>

$3\!\!\!\!\diagup\cdot\dfrac{n}{3\!\!\!\!\diagup}=(3)(-3)\\\\n=-9$

A pair of boots that originally sold for $75.32 are on sale for 22% off.

Vesnalui [34]

Answer:

The boots will be $58.75

Step-by-step explanation:

first you cross multiply

$\frac{x}{75.32}$ x $\frac{22}{100}$

you then get 1,657.04= 100x, so divide by 100 on both sides to get

16.5704 = X

Subtract X (the 22% discount amount) from the original price to get the new price of $58.75!
