An equation and the steps to solve it are shown below: step 1: 4x – 5x – 2 = 4 step 2: x – 2 = 4 step 3: x – 2 + 2 = 4 + 2 step 4: x = 6 in which step was the error made and why?

The error comes between steps 1 and 2.

Step-by-step explanation:

When we combine the like terms of 4x and -5x, then we get a -x. The problem above shows a positive x, which is incorrect.

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.  

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
