Answer:
All of the answers if you consider the dashes both negative and positive, but if they are negative then its the last 3 only.
Step-by-step explanation:
Answer:
times 5
Step-by-step explanation:
The given is that A B C D <span>x 4 = D C B A
</span><span>
Possible values of A are 1 or 2. It can't be 1 since the </span><span> </span><span>final result A is in unit place and 1 is not possible when we multiply any number by 4
</span><span>
2 B C D x </span><span>4 = </span><span>D C B 2</span>
It is clear above, that D = 8
2 B C 8 x <span>4 = </span><span>8 C B 2</span>
Possible values of B should be 1 or 2
We try B=1
2 1 C 8 x <span>4 = </span><span>8 C 1 2
</span>To find for C, you can use the equation:
(2000+100+10C+8) x 4 = 8000+100C+10+240C = 432-12 = 420
Therefore,
C = 7
So, the number is 2178.
Answer:
x = 2
Step-by-step explanation:
since both equal y, you can set them equal to each other
x + 4 = 3x + 0
subtract x on both sides
4 = 2x
divide by 2 on both sides
2 = x
