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:
As an improper fraction: 27 
As a mixed fraction: 
Step-by-step explanation:
Any number could be expressed as a fraction 27 is 
and since 0.43 is forty-three hundredths we can express it as .
To find the answer as a mixed fraction we have to put the whole number in the beginning and the fraction in the end. 27
As an improper fraction we have to add 27 / 1 + 43/100 =
Answer:
(0,-4)
Step-by-step explanation:
Answer:
I think Substitution
Step-by-step explanation:
Because x is already solved for in the second equation.
Answer:
The y-intercept would be 7
The slope would be -1 or -1/1. They are both the same thing.
The slope is the number which is located directly to the left of the variable (the variable in this case is x, but in other situations it could be a totally different letter).
