Recall that the sum of all interior angles in a triangle is 180°, and that a flat-line is always 180°.
Check the picture below.
<span>PV=NRT</span>If you want to solve that for n, remember that you can multiply or divide the whole equation by any number or expression as long as you do it to both sides. For example, if we divide both sides by R we get
<span><span><span>PVR</span></span>=NRT</span>or<span><span><span>PVR</span></span>=NT</span>after canceling R from both numerator and denominator on the right. Continue the process to solve for N.
Not quite sure but:
2/3 = 3/4
divide all by 2/3 to get a 1 value so
1 = 0.8
The two equations given are
3x + y = 17 and 4x - y = 18
Now we will first take one equation
3x + y = 17
Then
y = 17 - 3x
Now replacing the value of y in the second equation we get
4x - y = 18
4x - (17 - 3x) = 18
4x + 3x - 17 = 18
7x = 35
x = 35/7
= 5
Putting the value of x in the first equation we get
3x + y = 17
(3 * 5) + y = 17
15 + y = 17
y = 17 - 15
y = 2
So the value of x is 5 and y is 2
Answer:
8x+8
