Answer:

w = -3.6

Step-by-step explanation:

Simplifying

8.7 + w = 5.1

Solving

8.7 + w = 5.1

Solving for variable 'w'.

Move all terms containing w to the left, all other terms to the right.

Add '-8.7' to each side of the equation.

8.7 + -8.7 + w = 5.1 + -8.7

Combine like terms: 8.7 + -8.7 = 0.0

0.0 + w = 5.1 + -8.7

w = 5.1 + -8.7

Combine like terms: 5.1 + -8.7 = -3.6

w = -3.6

Simplifying

w = -3.6

$14 for a haircut plus a 15% tip anyone ???

Vlad [161]

Answer:

$16.10

Step-by-step explanation:

Simply take the original cost and multiply it by the percentage to get the tip amount then add it all together.

14 × 15% = 2.1

14 + 2.1 = 16.1

This means the haircut would cost a total of $16.10.

I need help breaking this down

sergeinik [125]

Answer:

see explanation

Step-by-step explanation:

Given

2cosΘ - $\sqrt{2}$ = 0 ( add $\sqrt{2}$ to both sides )

2cosΘ = $\sqrt{2}$ ( divide both sides by 2 )

cosΘ = $\frac{\sqrt{2} }{2}$

Since cosΘ > 0 then Θ is in first and fourth quadrants, hence

Θ = $cos^{-1}$ ( $\frac{\sqrt{2} }{2}$ ) = $\frac{\pi }{4}$

OR

Θ = 2π - $\frac{\pi }{4}$ = $\frac{7\pi }{4}$

solutions are Θ = $\frac{\pi }{4}$ , $\frac{7\pi }{4}$
