Sharla is 8 year older than her sister, patricia . The sum of their ages is 102.Find their ages.

Alisiya [41]

Answer:

Patricia is 47 years old

Sharla is 55 years old

Step-by-step explanation:

Rewrite the first sentence as an equation: (S= Sharla) (P= Patricia)

S=P+8

Rewrite the second sentence as an equation:

S+P=102

1) Substitute P+8 as Sharla in the second equation:

P+8+P=102

2) Combine alike terms:

2P+8=102

3) Subtract 8 from both sides:

2P=94

4) Divide both sides by 2:

P=47

5) Substitute 47 as P in the First equation:

S=47+8

6) Solve:

S=55

Solve: 2cos(x)-square root 3=0 for 0 less than x less than 2 pi

Leona [35]

Answer:

The general solution of $cos x = cos(\frac{\pi }{6})$ is

x = 2nπ± $\frac{\pi }{6}$

The general solution values

$x = - \frac{\pi }{6} and x = \frac{\pi }{6}$

Step-by-step explanation:

Explanation:-

Given equation is

$2cosx-\sqrt{3} =0 for 0$

$2cosx =\sqrt{3}$

Dividing '2' on both sides, we get

$cos x =\frac{\sqrt{3} }{2}$

$cos x = cos(\frac{\pi }{6})$

General solution of cos θ = cos ∝ is θ = 2nπ±∝

Now The general solution of $cos x = cos(\frac{\pi }{6})$ is

x = 2nπ± $\frac{\pi }{6}$

put n=0

$x = - \frac{\pi }{6} and x = \frac{\pi }{6}$

Put n=1

$x = 2\pi +\frac{\pi }{6} = \frac{13\pi }{6}$

$x = 2\pi -\frac{\pi }{6} = \frac{11\pi }{6}$

put n=2

$x = 4\pi +\frac{\pi }{6} = \frac{25\pi }{6}$

$x = 4\pi -\frac{\pi }{6} = \frac{23\pi }{6}$

And so on

But given 0 < x< 2π

The general solution values

$x = - \frac{\pi }{6} and x = \frac{\pi }{6}$
