Hello,
Let x represent the total of jumps
y represent the total “ raised the roof "

Here are two equation:
3x+2y=50
x+y=19
To solve this, I would prefer to use substitution because it is the easiest way to do:
x+y=19
Times 3 from both side
3x+3y=57
-
3x+2y=50
=
y=7
x=19-7=12. As a result, Roxanne jumps 12 , and “ raised the roof ” 7 times. Hope it help!

Answer:

This is an isosceles right triangle, then we have

2 x u^2 = [6sqrt(2)]^2

<=> 2 x u^2 = 72

<=> u^2 = 36

<=> u = 6

Hope this helps!

Anyone know how to do this? 15 points.
telo118 [61]

It's angles 9 and 10.

Supplementary angles are two angles that add up to 180°.

So, supplementary angles both "stick" off of a straight line. (Because a straight line is 180°).

4) If C, P, and T are the midpoints of the sides
marin [14]

Answers:

  • AE = 26
  • AN = 58
  • CT = 22.5
  • Perimeter of triangle AEN = 127

=========================================================

Work Shown:

Because points C, P, and T are midpoints of the sides of triangle AEN, this means the segments CP, PT, and CT are midsegments of triangle AEN.

The segment PT = 13 is a midsegment of the larger triangle, and it is parallel to the side AE. Recall the midsegment is half as long as its parallel side.

This means,

PT = (1/2)*AE

2*PT = AE

AE = 2*PT

AE = 2*13

AE = 26

---------------

We'll use the same idea to find AN

CP = (1/2)*AN

2*CP = AN

AN = 2*CP

AN = 2*29

AN = 58

---------------

And we can also say,

CT = (1/2)*EN

CT = (1/2)*43

CT = 22.5

----------------

Add up the sides of triangle AEN to find its perimeter

Perimeter of triangle AEN = (AE)+(EN)+(AN)

Perimeter of triangle AEN = (26)+(43)+(58)

Perimeter of triangle AEN = 127
