Find the values of x and y

arsen [322]

Answer:

x=18√6 , y=36√2

Step-by-step explanation:

${z}^{2} = 18 {}^{2} + 18 {}^{2} - 2(18)(18) \cos(90 ) \\ z = 18 \sqrt{2 } \\ \frac{x}{ \sin(60) } = \frac{z}{ \sin(30) } \\ x = 18 \sqrt{6} \\ \frac{y}{ \sin(90) } = \frac{z}{ \sin(30) } \\ y = 36 \sqrt{2}$

Tom, Mary and Bill are aged 10,12 and 15 years respectively. They share 259 euros in the same ratio as their ages. Find how much

tigry1 [53]

Answer:

70 , 84 , 105

Step-by-step explanation:

sum their ages , 10 + 12 + 15 = 37

divide the amount by this sum to find the value of one part of the ratio.

259 ÷ 37 = 7 ← value of 1 part of the ratio , then

10 parts = 10 × 7 = 70 euros ← Tom's share

12 parts = 12 × 7 = 84 euros ← Mary's share

15 parts = 15 × 7 = 105 euros ← Bill's share

Distribute then combine like terms in the following: 2(2x - 3y) - 3(x - 2y - 4) 4

nikdorinn [45]

I think its:

2(2x-3y)-3(x-2y-4)4

4x-6y-3x-6y(4)

4x-6y-3x-24y

x-30y
