The number 100 -> that has 2 zeros
Is the same as 10^2 as for this simplified is equal to 100.
100=100
They are the same. They have the same number of zeros.
-3b=-9. Plug in 3. -3(3)=-9.
I think c=9. I did the math...just trying to help but not exactly sure but I think it is...sorry
I haven’t done this in a while, but I believe that the “of” in the equation means multiply so you do 3/4 x 1/3 to get 3/12 (simplified to 1/4)!!
The interior angles of a 7 sided figure add up to 900o That's because if you pick any vertex of an angle and draw diameters so that you create triangles, you will get 5 triangles. In general the interior angles will add up to (n - 2)*180 where n is the number of sides of a polygon.
So the simple way to do this is to equate the seven angles + x to 900
Equation
x + 125 + 126 + 158 + 120 + 139 + 121 = 900
Solve
x + 789 = 900 Subtract 789 from both sides.
x = 900 - 789
x = 111 <<<<< answer
