L: 1750, M:1750-480=1270
Lisa gave some stamps to Mark so Lisa now has 1750-x and Mark has 1270+x. Mark also has 3 times as many as Lisa now: (1750-x)*3=1270+x
5250-3*x=1270+x
4*x=3980, x=3980/4, x=995
So Lisa gave 995 stamps to Mark.
At first Mark had 1270 stamps. Lisa now has 1750-995=755 stamps.

First, let's figure out what amount of stamps Mark originally had.

1750 - 480 = 1270

Mark originally had 1270 stamps.

Now, we have to figure out how many stamps Lisa has.

s = stamps

1270 + s = (1750 - s)3
1270 + s = 5250 - 3s
Add 3s to both sides.
1270 + 4s = 5250
Subtract 1270 from both sides.
4s = 3980
Divide both sides by 4.
s = 995

Now, subtract 995 from 1750.

1750 - 995 = 755

Lisa now has 755 stamps.

Quadrilateral JKLM is a rhombus. The diagonals intersect at N. If angle JNK equals 5x - 15, find the value of x.
VLD [36.1K]
One property of a rhombus is that the diagonals are perpendicular. This means that the diagonals intersect at 90 degree angles (right angles).

So we know that angle JNK is 90 degrees

angle JNK = 90 degrees
5x - 15 = 90
5x - 15 + 15 = 90+15
5x = 105
5x/5 = 105/5
x = 21

Answer: x = 21
