Step 1: Multiply 5x2 = 10 so the equation after the first step should look like this 10 + 12x + 8 = 0.
Step 2: Subtract 10 from the 8 and the number by itself cause whatever you do to one side you must do to the other. so the equation should look like this after the second step 12x + -2 = 0 because we subtracted the 10 and the 8.
Step 3: Now we must add the 2 to both sides because we have to do the inverse operation in this problem so once we've done this it should end up looking like this after the 3rd step 12x = 2 because the 2 was a negative.
Step 4: the final step we must divide since an anytime we have a number next to a variable it means multiply but since were using order of operations we have to do the opposite/inverse operation in this problem and we would divide 12 by 2 and get our final answer as x = -6 because the 12 would cancel itself out leaving us with 2 divided by 12 which is 0.16 or -6 depending on if you want it simplified or not the simplified answer would be 0.16 and the non simplified version would be -6
Diagonals of the parallelogram are congruent.
Answer:
First, identify your variables:
Let x = number of men in attendance.
Let y = number of women in attendance.
x + y = 48.
and
y = 12 + x
sub the second equation in for y in the first equation:
x + (12 + x ) = 48.
12 + 2 x = 48
2 x = 36
x = 18
y = 12 + 18
y = 30
Answer:
48
