Answer:
0.25
Step-by-step explanation:
1 divided by 4 = 0.25
The unknown number is n. So n is the unknown variable in the equation.
In order to write an equation in which n is included we must know some dependence of n with other values.
We know that <span>the difference of three times a number and 44 is −19. So, we can write:
3*n-44=-19
3*n=-19+44
3*n=25
n=25/3
</span>
give each letter a number: A=1, B=2, C=3, D=4
ADD = 1+4+4=9
BAD = 2+1+4 = 7
CAD = 3+1+4 = 8
So ADA = 1+4+1 = 6
