Since a triangle always equals 180 degrees, set all these variables equal to 180.
Lets try.
X+3+x+x= 180
Combine like terms
3x+3= 180
Subtract each side by 3
3x=177
Divide each side by 3
X= 59

On a road trip, Sara’s brother drove 47.5% of the trip, and Sara drove 80% of the remainder. If Sara drove for 4 hours and 12 mi

8090 [49]

80 percent of 52.5 percent of the trip is 42 percent
therefore, 4 hours and 12 min (or 252 min) is 42 percent of the trip
so
252/.42 = x/1
x = 600 min
the whole trip was 10 hours

-8.1

Step-by-step explanation:

$\frac{ - 4}{9} x + 2.4 = 6$

<em>Times </em><em>all </em><em>by </em><em>9</em><em> </em><em>to </em><em>get </em><em>rid </em><em>of </em><em>fraction</em>

<em> $- 4x + 21.6 = 54$ </em>

<em>Take </em><em>2</em><em>1</em><em>.</em><em>6</em><em> </em><em>away</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em>

<em> $- 4x = 32.4$ </em>

<em>Divide</em><em> </em><em>by </em><em>-</em><em>4</em>

<em> $x = - 8.1$ </em>

For what value of a does 9 equal 1/27 a + 3

Yakvenalex [24]

Answer:

a = 162

Step-by-step explanation:

9 = 1/27 a +3

Subtract 3 from each side

9-3 = 1/27 a +3-3

6 = 1/27 a

Multiply each side by 27

6*27 = 1/27 a *27

162 = a

Which equation is equivalent to log^x36=2?

Dennis_Churaev [7]

The equation which is equivalent to $\log _{x} 36=2$ is $x^{2}=36$ or x = 6 ( $\log _{6} 36=2$ ).

<u>Step-by-step explanation:</u>

Given Equation:

$\log _{x} 36=2$

As we know, in terms of logarithmic rules, when b is raised to the power of y is equal x:

$b^{y}=a$

Then, the base b logarithm of x is equal to y

$\log _{b}(x)=y$

Now, use the logarithmic rule for the given equation by comparing with above equation. We get b = x, y = 2, and x = 36. Apply this in equation,

$b^{y}=a$

$x^{2}=36$

When taking out the squares on both sides, we get x = 6. Hence, the given equation can be written as $\log _{6} 36=2$
