Answer:
N:ki n:kn:kNN
Step-by-step explanation:
You will have to get the difference and get a common denominator but first combine the mixed number:

Then subtract the numbers

Angel took 5/12 hours longer than Chris
Think the 4 less than but not equal to as a equal sign
step 1. isolate the variable ( variable must stand alone)
step 2. subtract 12n -12n=0
step 3. since you subtract 12n from the left you must do the same to the right.
step 4. 13n - 12n =1n
step 5. the equation should look like this -4 less than but not equal to 1n
step 6. isolate the variable n
step 6. divide 1n/1 on the right and on the left -4/1 it equals -4
so, n is -4
Answer:
y = 
Step-by-step explanation:
Given
y = 3xy - 1
Collect terms in y on the left side by subtracting 3xy from both sides
y - 3xy = - 1 ← factor out y on the left side
y(1 - 3x) = - 1 ( divide both sides by 1 - 3x
y =
← multiply numerator/denominator by - 1
y = 
Answer:
5/18
Step-by-step explanation:
6 and 3/4 = (6*4+3)/4 = 27/4. 1 and 7/8 = (8+7)/8 = 15/8. (15/8)/(27/4) = (15/8) * (4/27) = 60/216 = 30/108 = 15/54 = 5/18
