Answer:

The least common denominator is 21.

Step-by-step explanation:

First, you must find the least common factor of the two:

3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30

7: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70

Second, you must increase the fractions:

$\frac{1}{3}$ × $\frac{7}{7}$ = $\frac{7}{21}$ $\frac{3}{7}$ × $\frac{3}{3}$ = $\frac{9}{21}$

You gave the server at a restaurant a 22% tip and ended up paying $41.48. What was the price of your meal before you applied the

const2013 [10]

Answer: The price of meal before the tip = $34.

Step-by-step explanation:

Given : The percentage of tip = 22% = 0.22 ( we divide a percentage by 100 to convert it into decimal)

Total amount paid ( including tip) = $41.48

Formula for Total bill = Price of meal + Tip amount , where Tip amount= 22% of Price of meal.

Let x be the price of meal, then

Total bill =x + 0.22 x (x )

⇒ $41.48= x(1+0.22) [ By distributive property]

⇒ $41.48 = x (1.22)

⇒ x= ($41.48) ÷ 1.22

⇒ x= 34

Hence, the price of your meal before you applied the tip = $34.

Which shows one way to determine the factors of x^3 - 9x^2 + 5x - 45 by grouping ?

adoni [48]

You can group first two conjunctions and second two:
$x^3 - 9x^2 + 5x - 45=(x^3-9x^2)+(5x-45)$ .
In first brackets you have common $x^2$ and in second brackets common is 5:
$(x^3-9x^2)+(5x-45)=x^2(x-9)+5(x-9)=(x-9)(x^2+5)$ .
