Answer:

105

Step-by-step explanation:

180 - 140 = 40

180 - 145 = 35

35+ 40 = 75

180 - 75 = 105

a = 5

Answer:

105

Step-by-step explanation:

interior angle next to 145 is 180-145=35

interior angle next to 140 is 180-140=40

angle a= 180-35-40=105

I NEED HELP!! please show all work

Take the logarithm of both sides. The base of the logarithm doesn't matter.

$4^{5x} = 3^{x-2}$

$\implies \log 4^{5x} = \log 3^{x-2}$

Drop the exponents:

$\implies 5x \log 4 = (x-2) \log 3$

Expand the right side:

$\implies 5x \log 4 = x \log 3 - 2 \log 3$

Move the terms containing <em>x</em> to the left side and factor out <em>x</em> :

$\implies 5x \log 4 - x \log 3 = - 2 \log 3$

$\implies x (5 \log 4 - \log 3) = - 2 \log 3$

Solve for <em>x</em> by dividing boths ides by 5 log(4) - log(3) :

$\implies \boxed{x = -\dfrac{ 2 \log 3 }{ 5 \log 4 - \log 3 }}$

You can stop there, or continue simplifying the solution by using properties of logarithms:

$\implies x = -\dfrac{ \log 3^2 }{ \log 4^5 - \log 3 }$

$\implies x = -\dfrac{ \log 9 }{ \log 1024 - \log 3 }$

$\implies \boxed{x = -\dfrac{ \log 9 }{ \log \frac{1024}3 }}$

You can condense the solution further using the change-of-base identity,

$\implies \boxed{x = -\log_{\frac{1024}3}9}$

What is the solution to the equation below? 4x = ⅔

Nataly [62]

Step-by-step explanation:

we divide both sides by 4 to single out the X

(4X) / 4 = (2/3)/4

simplify

X = 2/12
