Answer:
3.666666667 + 2.333333333y
Step-by-step explanation:
Simplifying
3x + -7y = 11
Solving
3x + -7y = 11
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '7y' to each side of the equation.
3x + -7y + 7y = 11 + 7y
Combine like terms: -7y + 7y = 0
3x + 0 = 11 + 7y
3x = 11 + 7y
Divide each side by '3'.
x = 3.666666667 + 2.333333333y

Answer: 18900
Step-by-step explanation:
Given the question:
In 2001, the Guinness Book of World Records recognized a breakfast which served 18,941 people as the largest ever cooked. Which number below shows 18,941 rounded to 3 significant digits?
18,941 rounded to 3 significant figures
To round to 3 significant figures, the first 3 numbers are kept intact, then the subsequent number is rounded up to 1 if up to or greater than 5 and added to the third figure. If less than 5, all subsequent numbers are rounded down to 0
Hence,
18,941 = 18900 (because 4 is less than 5, 4 and all subsequent numbers are rounded down to 0).
