9x+27+15x
24x+27
Nine times x equals nine x. Then nine times three equals twenty-seven. Combine nine x and fifthteen x and you get twenty-four x.
(n + 8) + (n - 12)
Get rid of the parenthesis.
n + 8 + n - 12
Note : the (12) turns into a negative because a negative times a positive is always a negative :)
Combine like terms.
(n + n) + (8 - 12)
Simplify.
2n - 4

Answer:
The rental cost for each movie = 1.5 $
The rental cost for each video game = 6.5 $
Explanation:
Let the rental cost for movie be a and video game be b.
One month Diane rented 2 movies and 12 video games for a total of $81
2 a + 12 b = 81 $ -------------------------Equation 1
The next month she rented 5 movies and 3 video games for a total of $27
5 a + 3 b = 27 $ -------------------------Equation 2
Equation 2 x 4,
20 a + 12 b = 108 $ -------------------------Equation 3
Equation 3 - Equation 1,
20 a + 12 b - ( 2 a + 12 b ) = 108 - 81
18 a = 27
a = 1.5 $
Substituting in equation 1
2 x 1.5 + 12 b = 81
12 b = 81 - 3
b = 6.5 $
The rental cost for each movie = 1.5 $
The rental cost for each video game = 6.5 $
Answer:
k = 4, t = 2
Step-by-step explanation:
Express 2025 as a product of its prime factors
2025 = × 5², that is
× 5² = ×
Comparing exponents of same bases on both sides, gives
k = 4 and t = 2
