Answer:
51,129
Step-by-step explanation:
x+x+78=180(supplementary angles are 180)
2x+78=180
2x= 102
x= 51
x+78 = 129
<span>x y z are in geometric
x/y = y/z
OR y^2=xz
x^2, y^2, z^2
x^2, xz, z^2
If they are in geometric sequence then
xz/x^2 = z^2/xz
z/x = z/x
The ratios are common
so x^2,y^2 & z^2 is a GP.</span>
Absolute value<span> describes the distance of a </span>number<span> on the </span>number<span> line from 0 without considering which direction from zero the </span>number<span> lies. This pretty much means that absolute value is a distance, and there is no such thing as a negative distance.</span>
<span>Lets set an equation for each option. 1) School A: Charge = 750 + 200 = 950 per monts. 2) School B: 1000 less 10% discount from you employer. = 1000 - 1000*0.10 = 1000 - 100 = 900. Then, youcan save money going to School B, thanks to the discount that you will receive through your employer. </span>
Answer:
z=-15
Step-by-step explanation:
Multiply both sides by 3:
