Now, let's say there are "b" boys and "g" gals... ok... well, we know there are 116 more boys than gals..... so, if there are "g" gals then there must be "g + 116" boys.
what's the total class? well is g + b or g + ( g + 116).
Answer:
radius = 10
Step-by-step explanation:
As AB is the diameter of the circle, the angle ACB inscribes an arc of 180 degrees, so it is a 90 degrees angle, then the triangle ACB is a right triangle, with hypotenusa AB.
We can find the length of the diameter AB using the Pythagoras' theorem:
AB^2 = CA^2 + CB^2
AB^2 = 12^2 + 16^2 = 400
AB = 20
The radius of the circle is half the diameter, so the radius is 20 / 2 = 10
Do you have a chart or some other information?
Equation: -1/2x + 1 = -x + 8
Work:
-x/2 + 1 = -x + 8
1 - x/2 = -x + 8
1 - x/2 = 8 - x
2 - x = 16 - 2x
-x = 16 - 2x - 2
-x = 2x + 14
-x + 2x = 14
x = 14
Final Answer:
x = 14
Answer:
7 + (-3)
