Answer:
x + y +z= 10
Step-by-step explanation:
4x - y = 5 ---------(I)
4y - z = 7 ---------(II)
4z - x = 18 ---------(III)
Add all the three equations,
4x - y + 4y - z + 4z - x = 5 + 7 + 18
4x - x -y + 4y -z + 4z = 30
3x + 3y + 3z = 30
Divide the entire equation by 3
x + y + z = 10
Answer: 3 * y^(1/2)
Work:
Since the exponential form of any number is simply the number shown as broken down into its smallest pieces, you need to make each term exponential. Its helpful to break the 9 and the y apart when solving this and bring them back at the end. The expression then becomes (square root of 9) * (square root of y).
The square root of 9 can be simplified to 3.
The square root of y cannot be simplified but can be written in a form such that it becomes y^(1/2). The square root of any number is equal to that same number to the 1/2 power.
When you combine the terms back together, you are left with 3 * y^(1/2).
The answer is 2(3)(5^2) 150 is not a prime number
Since there are four pieces and each piece is 16 inches long, all you have to do is multiply 4 times 16 (4 × 16).
