Shopping at clothing world, jenna buys her children four shirts and three pairs of pants for 124.25. She returns the next day an

Aleksandr-060686 [28]

The cost of one shirt is 12.50 and cost of one pair of jeans is 24.75

Step-by-step explanation:

Let,

Cost of one shirt = x

Cost of pair of jeans = y

According to given statement;

4x+3y=124.25 Eqn 1

3x+5y=161.25 Eqn 2

Multiplying Eqn 1 by 3

$3(4x+3y=124.25)\\12x+9y=372.75\ \ \ Eqn\ 3$

Multiplying Eqn 2 by 4

$4(3x+5y=161.25)\\12x+20y=645\ \ \ Eqn\ 4$

Subtracting Eqn 3 from Eqn 4

$(12x+20y)-(12x+9y)=645-372.75\\12x+20y-12x-9y=272.25\\11y=272.25$

Dividing both sides by 11

$\frac{11y}{11}=\frac{272.25}{11}\\y=24.75$

Putting 24.75 in Eqn 1

$4x+3(24.75)=124.25\\4x+74.25=124.25\\4x=124.25-74.25\\4x=50$

Dividing both sides by 4

$\frac{4x}{4}=\frac{50}{4}\\x=12.50$

The cost of one shirt is 12.50 and cost of one pair of jeans is 24.75

A number to the 12th power divided by the same number to the 9th power equals 216. What is the number?

Annette [7]

Answer:

The given such number is 6.

Step-by-step explanation:

Let the given such number = m

Now, according to the question, the given expression is:

$\frac{(m^{12}) }{(m^{9}) } = 216$

By the LAW OF EXPONENTS:

$\frac{x^a}{x^b} = x^{(a-b)}$

⇒Here $\frac{m^{12}}{m^9} = m^{(12-9)} = m^{(3)}$

or, the given expression becomes $m^3 = 216\\\implies m = \sqrt[3]{216} = 6$

or, m = 6

Hence, the given such number is 6.
