Answer:
Correct me if Im wrong but I think that it is 3 to the -5th power
Step-by-step explanation:
Answer:
Boys : girls
5:6
Step-by-step explanation:
Boys : girls
20:24
We can divide each of these numbers by 4
20/4 =5
24/4 =6
Boys : girls
5:6
0.224 would be the correct answer
Answer:
x = 3 and -2 are the two solutions.
Step-by-step explanation:
2x^2 -2x -12 = 0
First factor out a 2
2(x^2 - x - 6) = 0
2(x - 3)(x + 2) = 0
2 = 0 x - 3 = 0 x + 2 = 0
2 does not equal zero so this is an extraneous solution
x - 3 = 0 so x = 3
x + 2 = 0 so x = -2
The top angle (10x+10) is equal to the angle below the lowest line and the skewed line. However, the 4x+2 is on the other side. But both together add up to 180° (a straight line).
So 10x+10 = 180-(4x+2) is the formula you're looking for.
Solving it:
10x+10 = 180-(4x+2) =>
10x+10 = 178-4x =>
14x = 168 =>
x = 12
Look up the theory for F angles and Z angles.
