Answer:
114
Step-by-step explanation:
Add 100 and 128 together and you get 228
Divide 228 by 2 and you get 114 - which is your average
Ratios can be written as fractions
24:28 = 24/28...this can reduce to 6/7....as a ratio 6:7
if that is not an answer choice, then any fraction that is equivalent to 24/28, written as a ratio will be ur answer
Answer:
7y = x + 28
Step-by-step explanation:
Given x = 7t and y = t + 4
Here t is the parameter Now to remove it express one of it in terms of the variables (like x or y)
Given x = 7t
from this we can write ![t=\frac{x}{7}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7Bx%7D%7B7%7D)
Now substitute this value in the second equation
y = t + 4
![y=\frac{x}{7}+4](https://tex.z-dn.net/?f=y%3D%5Cfrac%7Bx%7D%7B7%7D%2B4)
Therefore the parameter is eliminated.
Answer:
5 units
Step-by-step explanation:
If DG, EG and FG are perpendicular bisectors of the sides of triangle ABC, then point G is the circumcenter of the triangle ABC and
BG = AG = CG as radii of the circumcirle.
Consider right triangle BEG. By the Pythagorean theorem,
![BG^2=EG^2+BE^2\\ \\BG^2=4^2+3^2\\ \\BG^2 =16+9\\ \\BG^2=25\\ \\BG=5\ units](https://tex.z-dn.net/?f=BG%5E2%3DEG%5E2%2BBE%5E2%5C%5C%20%5C%5CBG%5E2%3D4%5E2%2B3%5E2%5C%5C%20%5C%5CBG%5E2%20%3D16%2B9%5C%5C%20%5C%5CBG%5E2%3D25%5C%5C%20%5C%5CBG%3D5%5C%20units)
This gives us that
AG = BG = 5 units
