Answer:
Step-by-step explanation:
J and K are equal
8x - 23 = 6x + 11 Add 23 to both sides
8x = 6x + 11 + 23 Combine the right
8x = 6x + 34 Subtract 6x from both sides
8x - 6x = 34 Combine the left
2x = 34 Divide by 2
x = 34/2
x = 17
=================================
M and L are both supplementary to J and K respectively.
J = 8x - 23
J = 8*17 - 23
J = 136-23
J = 113
K = 113
===================================
M + 113 = 180
M = 180 - 113
M = 67
L = 67
Answer: After 4 months they will have the same number of Stamps
Xian and Kai will have 124 stamps each one.
Step-by-step explanation:
60+16x = 76+12x (Subtract 12 from both sides)
-12 -12
60+4x = 76 (Subtract 60 from both sides)
-60 -60
4x/4x = 16/4x (Divide 16 by 4)
X = 4
Yes it is a right triangle
