Answer:

x = \frac{8\sqrt{3} }{3}

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin60° = \frac{\sqrt{3} }{2}

sin60° = \frac{opposite}{hypotenuse} = \frac{4}{x} = \frac{\sqrt{3} }{2} ( cross- multiply )

x × \sqrt{3} = 8 ( divide both sides by \sqrt{3} )

x = \frac{8}{\sqrt{3} } × \frac{\sqrt{3} }{\sqrt{3} } ( rationalising the denominator )

x = \frac{8\sqrt{3} }{3}

To solve this system using the addition method, you would need to multiply the first equation by what number in order for the y'
yanalaym [24]
You multiply 3x - y = 3.
So then it's:
6x - 2y = 3
-2x + 2y =6

which equals 4x = 9

a person invested $6300 for 1 year part at 8% part at 10% and the remainder at 15%. The total annual income from these investmen
Lunna [17]

Answer:

Step-by-step explanation:

let x be part at 8%, y be part at 10% and z be part at 15%

(1) x+y+z=6300

the amount of money invested at 15% was $100 more than the amounts invested at 8% and 10% combined. so

(2) z=x+y+100

The total annual income from these investments was $766. so

0.08x+0.1y+0.15z=766 or

(3) 8x+10y+15z=76600

substitute (2) into (1)

x+y+x+y+100=6300

(4) 2x+2y=6200

substitute (2) inot (3)

8x+10y+15(x+y+100)=76600

(5) 23x+25y=75100

solving (4) n (5)

x=1200

y=1900

z=1200+1900+100=3200
