Answer:. x = 18
Step-by-step explanation:
Solve by substitution. Given: y= 12x. Rewrite the original equation y= 180 + 2x to 12x = 180 +2x. Subtract 2x from both sides. 10x = 180. Then divide both sides by 10.
x=18

Answer:
The dimensions of constant C are of ![[L^{3}T]^{-4}](https://tex.z-dn.net/?f=%5BL%5E%7B3%7DT%5D%5E%7B-4%7D)
Step-by-step explanation:
It is given that
Since the dimensions of volume are ![[L^{3}]](https://tex.z-dn.net/?f=%5BL%5E%7B3%7D%5D)
Each of the term shall have a dimension of since they are in addition.
Thus for third term we can write
Thus we have
![[L^{3}]=[C][T^{4}]\\\\\therefore [C]=[L^{3}][T^{-4}]](https://tex.z-dn.net/?f=%5BL%5E%7B3%7D%5D%3D%5BC%5D%5BT%5E%7B4%7D%5D%5C%5C%5C%5C%5Ctherefore%20%5BC%5D%3D%5BL%5E%7B3%7D%5D%5BT%5E%7B-4%7D%5D)
Answer:
A: FG = ½GC
Step-by-step explanation:
Since AD, BC and CD are medians concurrent at G, it means G is the centroid.
Now, when median passes through the centroid, the centroid divides the median in the ratio of 2:1.
Also,that the median touches the side of the triangle at their midpoints.
Thus,by inspection, we can say that;
GD = ⅓AD
GC/FG = 2/1
Thus, GC = 2FG and FG = ½GC
BG = ⅔BE
Tbus,looking at the options given and what we have gotten in proof, we can say only FG = ½GC is correct.
