9. if lk = mk, lk = 7x-10, kn = x + 3, mn = 9x - 11. and kj = 28, find l.
lk: 7-10 kn +3 inox
lj = lk + kj
lj= 7x 28
lj = 78+ 38

Step-by-step explanation:

now even though I cannot find most of the answers for you I can tell you how to solve them, all you need to do is just input the equations that equal the letter pairs then sold them as if it was a find the x equation but in this case we're solving for L and not x

the infinity sign

step-by-step explanation:

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.
