Let adults = X
Then children would be 2x ( Twice as many as adults, means 2 times the amount of adults)
Now we have adults plus children equal 36:
X + 2X = 36
2X + X = 3x
Now we have 3X = 36
Divide both sides by 3 to solve for X
X = 36/3
X = 12
2X = 2*12 = 24
There were 12 adults and 24 children
Answer: y-3y
Step-by-step explanation: The expression -3y+y is equivalent to y-3y because both terms are the same but simply arranged in a different order; both -3y and y are in each equation.
.0012 as a fraction is 3/2500
Yes, you have the right answer for part 1.
But for the second part it should be A. Because if it is a square, it has to be both a rectangle and a rhombus, that is the only way to prove it.
We know it is a rhombus because we are given a right angle. And rhombus' diagonals are the perpendicular bisector of each other. we know the diagonals are both perpendicular bisectors because the segments divided are congruent, and it created a right angle. Therefore, it is a rhombus.
We know it is a rectangle because we know rectangles' diagonals are congruent. We can see all four segments are congruent, so "if congruent segments are added to congruent segments, then the sum is congruent". So the diagonals are congruent, showing it is also a rectangle.
So when a figure is both a rectangle and a rhombus, it is a square.

4 is wrong because a number gets smaller, not larger when you take 2.6 from it. 3-2.6 is 0.4
