You and a friend both work two different jobs. The system of linear equations represents the total earnings for 2 hours worked at the first job and y hours worked at the second job. Your friend eams twice as much as you.
4x+8y=64
8x + 16y=128
a. One week, both of you work
hours at the first job. How many hours do you and your friend work at the second job?
You and your friend word
hour(s) at the second job.
b. Both of you work the same number of hours at the second job. Compare the number of hours each of you works at the first job. 4x+8y=64 8x+16y=128

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.
