Multiply through the parenthesis:
6x - 3 = -51
Combine like terms:
6x = -48
Divide by 6 on both sides:
x = -8

How many degrees is the angle measurement of

Komok [63]

Answer:

x° = 37.13°

Step-by-step explanation:

13.4 = cathetus opposite the angle "x°"

22.4 = hypotenuse

$sin(x^{o}) =\frac{13.4}{22.2}=0.6036$

$x^{o} =sin^{-1} (0.6036)=37.13^{o}$

Hope this helps

PLEASE HELP ASAP!!!!

Naily [24]

Answer:

2

Step-by-step explanation:

Using the rule of logarithms

$log_{b}$ x = n ⇒ x = $b^{n}$

let

$log_{2}$ 8 = n ⇒ 8 = $2^{n}$ , that is

2³ = $2^{n}$ ( equate exponents )

n = 3

and let

$log_{3}$ ( $\frac{1}{3}$ ) = n ⇒ $\frac{1}{3}$ = $3^{n}$ , that is

$3^{-1}$ = $3^{n}$ ( equate exponents )

n = - 1

then

$log_{2}$ 8 + $log_{3}$ ( $\frac{1}{3}$ )

= 3 + (- 1)

= 3 - 1

= 2
