-6 + x/4 = -5
First, you need to combine like terms.

x/4 = 1
now, you need to isolate the variable, so multiply both sides by four.

you get

2x-4/5=4<br> plsss answer quick
nikdorinn [45]

Answer:

<h2>x = 12</h2>

Step-by-step explanation:

\frac{2x - 4}{5}  =4

First of all multiply through by 5 to eliminate the fraction

That's

5 \times  \frac{2x - 4}{5}  = 4 \times 5 \\ 2x - 4 = 20

Next using the addition property add 4 to both sides of the equation

We have

2x - 4 + 4 = 20 + 4 \\ 2x = 24

<u>Divide both sides by 2</u>

\frac{2x}{2}  =  \frac{24}{2}

We have the final answer as

<h3>x = 12</h3>

Hope this helps you

Find b, given that a = 20, angle A = 30°, and angle B = 45° in triangle ABC
Kamila [148]
<span>The side b is opposite to the angle B, applying the law of the sines, we have:

</span>\frac{a}{sinA} = \frac{b}{sinB}
\frac{20}{sin30^0} = \frac{b}{sin45^0}
\frac{20}{ \frac{1}{2} } = \frac{b}{ \frac{ \sqrt{2} }{2} }
20* \frac{ \sqrt{2} }{2}  = b* \frac{1}{2}
\frac{20 \sqrt{2} }{2} = \frac{b}{2}
2*b =2*20 \sqrt{2}
2b = 40 \sqrt{2}
b =  \frac{40 \sqrt{2} }{2}
\boxed{b = 20 \sqrt{2} }
