Answer:
n = -5
Step-by-step explanation:
Solve for n:
n + 2 = 4 n + 17
Hint: | Move terms with n to the left hand side.
Subtract 4 n from both sides:
(n - 4 n) + 2 = (4 n - 4 n) + 17
Hint: | Combine like terms in n - 4 n.
n - 4 n = -3 n:
-3 n + 2 = (4 n - 4 n) + 17
Hint: | Look for the difference of two identical terms.
4 n - 4 n = 0:
2 - 3 n = 17
Hint: | Isolate terms with n to the left hand side.
Subtract 2 from both sides:
(2 - 2) - 3 n = 17 - 2
Hint: | Look for the difference of two identical terms.
2 - 2 = 0:
-3 n = 17 - 2
Hint: | Evaluate 17 - 2.
17 - 2 = 15:
-3 n = 15
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of -3 n = 15 by -3:
(-3 n)/(-3) = 15/(-3)
Hint: | Any nonzero number divided by itself is one.
(-3)/(-3) = 1:
n = 15/(-3)
Hint: | Reduce 15/(-3) to lowest terms. Start by finding the GCD of 15 and -3.
The gcd of 15 and -3 is 3, so 15/(-3) = (3×5)/(3 (-1)) = 3/3×5/(-1) = 5/(-1):
n = 5/(-1)
Hint: | Simplify the sign of 5/(-1).
Multiply numerator and denominator of 5/(-1) by -1:
Answer: n = -5
For every 5 cashews, there are 6 peanuts and 7 almonds.
Means: Cashews:Peanuts:Almonds = 5:6:7
Sum of ratio = 5 + 6 +7 = 18
Cashews = (5/18) * 270 = 75
Peanuts = (6/18) * 270 = 90
Almonds = (7/18) * 270 = 105
So how many more what are there than peanuts?
The number of that nuts Minus the number of peanuts.
= Number of that nuts - 90
Answer: 36x^2

<h2>
Answer:</h2><h2>
The rate of reading a book per month = 
= 20%</h2>
Step-by-step explanation:
Nathan read 2 books in 10 months.
The time taken to complete 1 book = 
= 5 months
To complete 1 book it takes 5 months.
The rate of reading a book per month = = 20%
For #3, it's 5.4 because you divide the total amount of money made by the amount of money earned per hour.
49.95/9.25=5.4 hours
