Answer:
x= 942.22
Step-by-step explanation:
.9x-18=830
.9x=848
x=942.222222222
which will be x= 942.22
Deandre = x
Kala = x + 6
Eric = 3(x+6)
x + x + 6 + 3(x+6) = 119
2x + 6 + 3x + 18 = 119
5x + 24 = 119
5x = 95, x = 19
Deandre has $19
Kala has 19 + 6 = $25
Eric has 3(25) = $75
This is a probablity question
there are 3 slots, 26 letters of the alphabet
so in the first slot, we have 26 possible letters
2nd slot, we have 25 possible letters (we used one for the first slot)
3rd slot, we have 24 possible letters, (we used 2 for first and 2nd slot)
so in total, we have 26*25*24 or 15600 different 3 letter initials with no repeated letters
Answer:

Step-by-step explanation:
2 divided by 6 is 
To confirm it,

Answer:
no solution
Step-by-step explanation:
Given the 2 equations
y =
x + 4 → (1)
-
x + y = - 5 → (2)
Substitute y =
x + 4 into (2)
-
x +
x + 4 = - 5 , that is
4 = - 5 ← not possible
This indicates the system has no solution
