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...

−4x−2 + 3y0 if x = 2 and y = 5
Kazeer [188]

Hey there!

-4x^-2 + 3y^0

= -4(2)^-2 + 3(5)^0

= -4(1/4) + 3(5)^0

= -1 + 3(5^0)

= -1 + 3(1)

= -1 + 3

= 2

Therefore, the answer should be: 2

Good luck on your assignment and enjoy your day!

Pls answer this question correctly and I will mark it has brainlist please
densk [106]

Answer:

18.5

Step-by-step explanation:

First find the area of the two triangles.

1.5 * 1.5 = 2.25

Find the area of the two top rectangles: 2.5 * 1.7 * 2 = 8.5

Finally, find the area of the floor: 1.5 * 2.5 = 3.75

2.25 + 8.5 + 7.75 = 18.5

Which of the following is a true statement about the triangles shown on the graph
sveticcg [70]
It's D. Slopes are the same, because if you divide opposite and adjacent side of both triangles, you get the same result. Count the squares, for the smaller triangle it's 2/2=1 and for the bigger one it's 4/4=1.
