Answer:
1) n + 7 = 20
2) x + 7 = 14
3) x + n = 21
4) 11 +n = 19
5) x - 17 = 14
6) 12 - x = 8
7) x - 4 = 30
8) 8x = 56
9) 1/2n = 18
10) 2(n > 4) = 12
11) 4n = 12
12) n + 2 = 14
13) n - 10 = 4
14) n - 2 = 8
15) n - 2 = 9
16) 2n - 3 = 17
17) 2n - 10 = 22
18) 3n - 6 = 13
19) 2n - 9 = 7
20) 2(n < 3) = 13

Answer:
f = 
Step-by-step explanation:
Given
b = fjn ( isolate f by dividing both sides by jn )
= f
Answer:
3x+.6y+12
Step-by-step explanation:
DIvide everything by -4:
-12x+2.4y-48
-12x/-4=12x/4=3x
2.4y/-4=-.6y
-48/-4=12
log (m + n) = log m+ log n and proved it m =n/n-1
Given;
If log (m + n) = log m+ log n
To show that the m =n/n-1
Now, According to the question:
We know that,
Log (m + n) = log m + log n
Log (m + n ) = log (mn). [log a + log b = log ab ]
Cancelling the log on both sides.
then,
m + n = mn
=> n = mn - m
=> n = m (n - 1)
=> m = n / n - 1
Hence Proved
log (m + n) = log m+ log n and proved it m =n/n-1
What is Logarithm?
A logarithm is the power to which a number must be raised in order to get some other number (see Section 3 of this Math Review for more about exponents). For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2.
