Answer: 6^8 / 12^8
Step-by-step explanation:
To simplify the expression (6^4/12^4)^2 as a single power, you can use the properties of exponents.
First, simplify the numerator and denominator separately:
(6^4/12^4)^2 = (6^4/12^4) * (6^4/12^4)
Now, use the fact that (a/b)^2 = a^2 / b^2:
= (6^4 * 6^4) / (12^4 * 12^4)
Next, use the properties of exponents to combine the like bases:
= 6^(4+4) / 12^(4+4)
= 6^8 / 12^8
Now, you can simplify further by dividing both the numerator and denominator by a common power of 12 (in this case, 12^8):
= (6^8 / 12^8) / (12^8 / 12^8)
= (6^8 / 12^8) / 1
= 6^8 / 12^8
So, (6^4/12^4)^2 simplifies to 6^8 / 12^8 as a single power.
Answer: y = 3x + 60
Step-by-step explanation:
Set up two equations and solve the system:
270 = 70x + b
- (150 = 30x + b)
120 = 40x
3 = x
Input "x" into one of the equations and solve for "b":
150 = 30x + b
150 = 30(3) + b
150 = 90 + b
60 = b
Equation: y = 3x + 60
This means that there is a flat fee of $60 plus a rate of $3 per student
The fixed rate of gym fee of $60 plus a rate of $3 per student.
The fixed-rate is;
Given
I rent a gym for $150.00 for 30 students.
Another time I rent the gym for $270.00 for 70 students.
A linear function is a function that forms a straight line in a graph.
Let x be the number of students and y be the total cost of renting the gym.
To find the fixed-rate let us write the equation of line representing the total cost of renting a gym for x students.
The equation representing a fixed rate is;
I rent a gym for $150.00 for 30 students.
Another time I rent the gym for $270.00 for 70 students.
Subtracting both the equations;
Substitute the value of x in equation 1
Therefore,
The fixed-rate is;
Hence, the fixed rate of gym fee of $60 plus a rate of $3 per student.'

What is the cost of a large box of tangerines?
Answer:
11s + 10l = 146
5s + 12l = 126
$8
Step-by-step explanation:
Let :
Small box = s
Large box = l
11s + 10l = 146 - - - - (1)
5s + 12l = 126 - - - - (2)
Multiply (1) by 5 ; (2) by 11
55s + 50l = 730
55s + 132l = 1386
Subtract
-82l = - 656
l = 8
11s + 10(8) = 146
11s + 80 = 146
11s = 66
s = $6
Hence, the price of a large box of tangerine = $8
