Answer: The <u>ten ounce drink</u> is a better deal.
The Explanation: Why? Well, since you are getting 10 ounces of a drink you spend only 32 cents on each ounce whereas with the 6 ounces you end up spending 36 cents per ounce. You might be spending more money on the ten ounces but when you break down the cost of the drink per ounce you figure out that it is the best deal possible!
Answer:
Correct option is
B
10
Given2
2x−y
=32
⇒2
2x−y
=2
5
⇒2x−y=5−−−−(1)
Again2
x+y
=16
⇒2
x+y
=2
4
⇒x+y=4−−−−(2)
Adding(1)and(2)weget
3x=9
⇒x=3
Substitutingx=3in(2)weget
y=1.
∴x

Answer:
let x and y be two integers then this number line can be represented as linear equation with two variable
2x-3.1y= -1.1
here x and y could be 1
<u>From the Pythagoras's Theorem, we know that:</u>
(Hypotenuse)² = (base)² + (perpendicular)²
<u>We are Given:</u>
We are given that the 2 legs (Base and Perpendicular) of the triangle are (m²-n² and 2mn)
<u>Solving for the Hypotenuse:</u>
replacing the variables in the Pythagoras's theorem, we get:
Hypotenuse² = (m²-n²)² + (2mn)²
Hypotenuse² = (m⁴ -2m²n² + n⁴) + (4m²n²) [<em>(a-b)² = a² - 2ab - b²</em>]
Hypotenuse² = m⁴ -2m²n² + n⁴ + 4m²n²
Hypotenuse² = m⁴ + 2m²n² + n⁴
Hypotenuse² = (m²)² + 2m²n² + (n²)²
Hypotenuse² = (m² + n²)² [<em>a² + 2ab + b² = (a+b)²</em>]
<em>taking the square root of both the sides</em>
Hypotenuse = m² + n²
