32+20=52 so there are 52 people in all.
32/52 people are men.
we now have to subtract 1 from this fraction like so 32-1/52-1 since the magician took away 1 man from the audience (therefore reducing the amount of men as well as the audience as a whole) resulting in 31/51
we multiply 32/52 with 31/51 to get 248/663. simply turn this fraction into a percent by multiplying the quotient by 100 and rounding it to the nearest tenth to get 37.4%
-2 < -3 (I think so anyway)
Answer:
Step-by-step explanation:
The median is the average of the lengths of the two bases:
5x -20 = (12 + (4x -10))/2
5x -20 = 2x +1
3x = 21 . . . . . add 20-2x
x = 7
Then the lengths are ...
median = 5x -20 = 5·7 -20 = 15
base = 4x -10 = 4·7 -10 = 18
Answer:
C. x = 1
Step-by-step explanation:
When we have an undefined slope, we have a vertical line of x = [a number]. This isn't a function and we have an undefined slope because we don't know what m equals in y = mx + b.
Answer:
The solution is 
Step-by-step explanation:
You are given the system of three equations:

Multiply the first equation by 4, the second equation by 3 and subtract them. Then multiply the third equation by 2 and subtract it from the second equation:

So,

Multiply the third equation by 23 and subtract it from the second equation:

Hence,

Substitute it into the second equation:

Substitute them into the first equation:

The solution is
