What is the value of x in the equation 3x-4y=65 when y=4?

Simple...plug n chug..

3x-4(4)=65

3x-16=65

Now, isolate the variable, x....

3x-16=65
+16 +16

3x=81

Now, divide,

$\frac{3x}{3} = \frac{81}{3}$

x=27.

Thus, your answer.

Find the length of arc PQ. Round to the nearest tenth.

vladimir1956 [14]

Answer:

The length of arc PQ to the nearest tenth is 8.1 inches.

Step-by-step explanation:

Let the measure of arc PQ be 'x'.

Given:

The measure of arc SR = 150°

The measure of arc QR = 65°

The measure of arc PS = 73°

Radius of the circle is, $R=6.48\ in$

Sum of the measures of all arcs in a circle is always 360°. Therefore,

Arc PQ + Arc QR + Arc SR + Arc PS = 360°

$x+65+150+73=360\\x+288=360\\x=360-288=72\°$

Now, the arc length is given as:

$\textrm{Arc length}=R\theta\\Where\ \theta\rightarrow arc\ measure\ in\ radians$

Now, measure of arc PQ, $\theta=72\°=72\times \frac{\pi}{180}=0.4\pi$

Therefore, arc length PQ = $6.48\times 0.4\pi=2.592\times 3.14=8.138\approx 8.1\ in$

So, the length of arc PQ to the nearest tenth is 8.1 inches.

I don't know which one please help

ch4aika [34]

The answer is (A) 15.

(6x -10) makes 80 and (6x+10) makes 100

together that equales 180 degrees. since it is a straight line the sum of the the two would have to equal 180. hope this helped :D
