Yuson must complete 30 hours of community service. She does 2 hours each day. Write a linear equations to represent the hours Yuson has left after x days.

Linear equation which represents the hours Yuson has left after x days is:

30-2x

Step-by-step explanation:

Yuson must complete 30 hours of community service.

She does 2 hours each day.

i.e. in x days, hours of service done= 2x

After x days hours of service left= 30-2x

Hence, linear equation which represents the hours Yuson has left after x days is:

30-2x

which expression can be used to convert 80 us dollars (usd) to australian dollars (aud)?

1 usd = 1.0343 aud

1 aud = 0.9668 usd

step-by-step explanation:

sorry just need the points

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.
