How many 3-digit numbers exist, whose digits are distinct even numbers.
skad [1K]

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.

-7 - 17 = 2x + 10<br> Solve for x.
rjkz [21]

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
