Answer:
328
Step-by-step explanation:
If z is 0, then x has 9 choices. Therefore, z and x can be chosen in (1 × 9) + (4 × 8) = 41 ways. For each of these ways, y can be chosen in 8 ways. Hence, the desired number is 41 × 8 = 328 numbers 3-digit even numbers exist with no repetitions.
Combine the like terms:
-15 - 19 = -34
6x - 20x = -14x
The answer would be -34-14x or -14x-34
Answer:
x= -17
Step-by-step explanation:
-7-17=2x+10
subtract -7 to -17 but since both are negatives you do addition.
-24=2x+10
add 24 from both sides and put 2x as a negative
-2x=34
divide both sides by -2

x= -17
