phobe, Andy and polly share £270 phobe gets 3 times as much as Andy who gets twice as much as polly work out how much they each

Lady bird [3.3K]

Answer:

<h2>Andy = £ 60</h2><h2>Phobe=£ 180</h2><h2>Polly= £ 30</h2>

Step-by-step explanation:

Let ,

Andy gets £ X

Phone gets 3x

Polly gets y = X/2

Andy gets 2y

2y = X

Now,

$x + 3x + \frac{x}{2} = 270 \\ \frac{x \times 2 + 3x \times 2 + x}{2} = 270 \\ \frac{2x + 6x + x}{2} = 270 \\ \frac{9x}{2} = 270 \\ 9x = 270 \times 2 \: ( \: cross \: multiplication) \\ 9x = 540 \\ x = \frac{540}{9} \\ x = 60$

Replacing values,

$phobe \: gets = 3x \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3 \times 60 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 180$

$polly \: gets = \frac{x}{2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{60}{2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 30$

Hope this helps...

Good luck on your assignment..

A rectangular garden has a walkway surrounding it that is 4 feet wide (a uniform width

Oksana_A [137]

Answer: 300 square feet

Step-by-step explanation:

length of walkway = 20 + 2x

width of walkway = 15 + 2x

A(x) = (20 + 2x)(15 + 2x)

A(x) = 300 + 30x + 40x + 4x2

A(x) = 300 + 70x + 4x2

Can someone help??plzzz..

When you are multiplying 2 numbers with exponents, you need to add the exponent. When you multiply an exponent with an exponent, you multiply them.

So,
(3^2 x 7^4) ^9
First multiply the base and add exponents = ( 21^6) ^9
= 21 ^6x9
21^54
The same rule applies for variables, just pretend there is an imaginary 1.
