Answer:
x = 65
Step-by-step explanation:
To solve the equation, we write it in radical form:
![5\, \sqrt[3]{x-1} = 20](https://tex.z-dn.net/?f=5%5C%2C%20%5Csqrt%5B3%5D%7Bx-1%7D%20%3D%2020)
Then, we divide both sides by 5 to isolate the root:
![\sqrt[3]{x-1} = \frac{20}{5} \\\sqrt[3]{x-1} =4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx-1%7D%20%3D%20%5Cfrac%7B20%7D%7B5%7D%20%5C%5C%5Csqrt%5B3%5D%7Bx-1%7D%20%3D4)
and next, we raise both sides of the equation to the power 3 so as to free the expression in x from the root:

now we add 1 to both sides to isolate x:
x = 65
Parentheses aka 3+2, so D
The length of lace would be the circumference of the circle.
Circumference = diameter x Pi
Circumference = 16pi cm
Circumference = 50.24 cm ( approximately)
Answer:
x = 5/4
Step-by-step explanation:
5x - 6 = 4 - 3x
8x - 6 = 4
8x = 10
x = 5/4
The error is that -3x is moved across the = in an incorrect manner. You instead need to add the 3x across the = ending up with 5/4. Adding this across negates the negative which makes it 8x, the rest of the step are as follows.
