How do you solve equations with rational coefficients?

Answers

Answer 1

Answer:
You've been doing that all this time and didn't even realize it !

Every plain old number that you ever see is a rational number.
Every equation that has plain old numbers next to the variables
is an equation with rational coefficients.

If a variable ever has (pi) or a square root or a trig function next to it,
then that's an irrational coefficient. But I'll just bet you haven't ever
seen any of these yet.

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Robert slices a large loaf of bread to make 12 sandwiches. He made 3 turkey sandwiches and 5 veggie sandwiches. The portion of the ham sandwich will be calculated as below:-

Total sandwich = Turkish sandwich + veggie sandwiches + ham

12 = 5 + 3 + ham

ham = 12 - 8 = 4

Therefore, the fraction of the ham sandwich will be 4.

Darrin put the numbers 7.25, 7.52, and 5.72 and 5.27 in order from greatest to least.Is his work correct?Explain

Answers

if the order of the numbers in the question are the order Darrin put theem in then no, his work is not correct. this is because 7.25 is not greater than 7.52. the real order should be 7.52,7.25, 5.72, 5.27

His work was incorrect, the number has the most value is the greatest number
Because 7 > 5, then 7.25 and 7.52 will be 1st and 2nd numbers and 5.72 and 5.27 will be 3rd and 4th numbers.
Let's compare 7.25 and 7.52
Because 2 < 5 (the tenth digit) so 7.52 is 1st number and 7.25 is the 2nd number
Now, compare 5.72 and 5.27, again, 7 > 2 (the tenth digit) so 5.72 is 3rd number and 5.27 the 4th number.
Totally, the order from greatest to least is 7.52 , 7.25 , 5.72 , 5.27
