Answer:
(1,2.16), (2,4.32) and (3, 6.48).
The solution (1,2.16) means that 1 cubic units of pudding weighs 2.16 pounds.
The solution (2,4.32) means that 2 cubic units of pudding weighs 4.32 lbs.
Step-by-step explanation:
The equation y=2.16x describes the weight y of x cubic pounds of pudding.
The three solutions of this equation are (1,2.16), (2,4.32) and (3, 6.48).
Now, solution (1,2.16) means that 1 cubic unit of pudding weighs 2.16 pounds.
Again, solution (2,4.32) means that 2 cubic units of pudding weigh 4.32 lbs. (Answer)
Answer: Area= 459.73cm^2
Step-by-step explanation: Circumference of a circle is 2πr
76=2×3.14×r
r= 76÷(6×3.14)
r=12.10
Area of a circle= πr^2
Area= 3.14×(12.10)^2
Area= 456.73cm^2
The solutions to the given equation containing absolute value term |3x-7| - 7 = x are 0 and 7.
<h3>What are the solutions to the given equation?</h3>
Given the equation in question;
|3x-7| - 7 = x
First, add 7 to both sides.
|3x-7| - 7 + 7 = x + 7
|3x-7| = x + 7
Next, remove the absolute value term, this creates a ± on the right side of the question.
|3x-7| = x + 7
3x-7 = ±( x + 7 )
The complete solution is the result of both the negative and positive portions of the solution.
For the first solution, use the positive of ±.
3x-7 = ( x + 7 )
3x - 7 = x + 7
3x - x = 7 + 7
2x = 14
x - 14/2
x = 7
For the second solution, use the negative of ±.
3x-7 = -( x + 7 )
3x-7 = -x - 7
3x + x = -7 + 7
4x = 0
x = 0/4
x = 0
Therefore, the solutions to the given equation containing absolute value term |3x-7| - 7 = x are 0 and 7.
