Write an equivalent expression of 8m-(5+2m) without parentheses

6m-5

Step-by-step explanation:

first you have distribute the negative to the equation in the parentheses so you get

8m - 5 - 2m

Then combine the like terms

So the final answer is 6m-5

6m - 5

Rewriting the expression above without parentheses is done by simply removing the parentheses using the negative sign. Note that the signs of the constant (5) and term (8m) in the expression are positive (+). Thus, using the negative sign to remove the parentheses will be done using the arithmetic signs rule: - × + = -, that is, minus times plus equals minus; such that - × + 2 = - 2 and - × +8m = -8m.

=> 8m - 5 - 2m

=> 8m - 2m - 5

=> 6m - 5

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
