"Alternate" means the angles are on opposite sides of the transversal.

Any of angles 1, 4, 5, and 8 are alternate with any of angles 2, 3, 6, and 7.

1 and 5, 1 and 8 are "same side" angles (not alternate), so those answer choices can be excluded from consideration.

___

"Exterior" means that the angles are outside (not between) the parallel lines. Angles 1, 2, 7, 8 are exterior angles. Angles 3, 4, 5, 6 are interior angles (between the parallel lines). Thus answer choice "4 and 6" can be excluded from consiideration.

The appropriate (and only remaining) choice for "alternate exterior angles" is ...

... 2 and 8

_____

Angles 1 and 7 are also alternate exterior angles, but that selection is not on your list of answer choices.

A square and a rectangle have the same perimeter. The square has a side length of 8x units. The rectangle has a length of (10x+8

Elden [556K]

Well we know that the perimeters are equal so:
Psquare = Prectangle

we know perimeter for square is the 4 sides of same lengths added up or 4*s

the perimeter of a rectangle is the then4 sides with 2 being equal added up so 2*L + 2*W

we know that a square side equAls s and it says that s=8x. So:
Psqu = 4 * (8x) (substitute 8x for s)

we know that the rectangle L =10x + 8 and W =10. So
Prect = 2 *(10x + 8) + 2 * (10)

we know :
Prect = Psqu so:
4 * (8x) =2 *(10x + 8) + 2 * (10)
32x = 20x + 16 + 20
12x = 36
x = 3

So if x equals 3 we can sub x in for square perimeter
Psqu = 4 *(8 * 3)
P = 4 * 24
P = 96

we can check this with rectangle perimeter
P = 2 *(10 * 3 + 8) + 2 *10
P = 2 * 38 + 20
P = 96

Can you solve this problem? Help I need it fast and could you tell me how to do it? Thank you!

bixtya [17]

So for me, how I would do it is move the variables and numbers to one side. So we have the equation 3x-3=2/5x+7. So you would subtract 2/5x to the left side and add 3 to the right side. The equation will then turn out to be 3x-2/5x=7+3. Much more easier right? So just simplify both side, and you will get 13/5x=10. In order to isolate x, you have to divide 13/5 in both side, leaving x= 3 11/13 or 50/13. You can always plug the answer back in to double check :)

at one of george washington's parties, each man shook hands with everyone except his spouse, and no handshakes took place betwee

Keith_Richards [23]

The total number of handshakes was 234.

The first man shook hands with 12 other men.
The second man shakes hands with 11 other men, as he had already shaken hands with the first man.
Like-wise, the last man does not need to shake hands again as every man has already shaken hands with him in their respective turns.
The number of handshakes among men is 0 + 1 + 2 + … + 12.
The sum of "n" natural numbers = (n)(n+1)/2
The number of handshakes among men is 12(13)/2.
The number of handshakes among men is 78.
Each man shakes hands with every woman except his spouse.
Each man shakes hands with 12 other women.
The number of handshakes between men and women is 13*12.
The number of handshakes between men and women is 156.
The total number of handshakes is 78 + 156.
The total number of handshakes is 234.
