X-Y = 14, X+Y = 20, then x=14+Y. Replace x so (14+Y) + Y =20 so 2Y = 6, Y=3 and x=17

Given:

$x^{\frac{m}{n}}$

The expression can be used to express powers and roots together.

Here, we can rewrite this as:

$x^{\frac{m}{n}}=\sqrt[n]{x^m}\text{ = (}\sqrt[n]{x})^m$

Here, m is the power while n is the root.

Therefore, m represents the power to which x is raised while n represents the root that is being taken.

kicyunya [14]

Answer:

Original price of bicycle = $864

Step-by-step explanation:

Given:

Rate of tax = 20%

Price pay by Mathew = $1,080

Find:

Original price of bicycle

Computation:

Original price of bicycle = Price pay by Mathew[1 / (1-20%)]

Original price of bicycle = 1,080[1 / (1-20%)]

Original price of bicycle = 1,080[1 / (1-0.2)]

Original price of bicycle = 1,080[1 / (0.8)]

Original price of bicycle = 1,080[1.25]

Original price of bicycle = $864

A house purchased for $216,500 gains 2% of its value every year. If this growth rate continues, in how many years will the house

NikAS [45]

Answer: 36 years

Step-by-step explanation:

You can use the Rule of 72 to calculate how long it might take the house to double in value.

The Rule of 72 works by dividing 72 by the interest rate as a whole number and the result will be a rough estimate of the time in years it will take for the investment to double in size:

= 72 / 2

= 36 years
