Answer:
my answer was 7.5
Step-by-step explanation:
2
2b+3b-10
4b+3b-10
10-7b=3b fraction bar means divide so...
3b
__ 2
4b because... b-2b=4b and 8-4b=4b
3/4 =7.5 because 4 cant go into three so you add a decimal and a zero and move decimal up and 4 can go into 30 7 time which equals 28 and 30-28 is 2 add another zero and its 20 and 4 goes in 5 times which equals 20 and 20-20=0 so its 7.5 (i hope this helps ;)

Answer:
x=3
Step-by-step explanation:
all work is shown and pictured
remember PEMDAS or order of operations
it's the order in which to simplify stuff
P: parenthasees (or grouping symbols like brackets or such), remember to work inside to out
E: exponents (includes square roots since they are fractional exponents)
M & D: multtiplication and divions, I do whichever comes first since division is just multiplication by a fraction
A & S: addition and subtraction, I do whichever comes first since subtraction is addition of a negative
[(30+6)-30] / 9 * 2
parenthases first, do innermost first
(30+6) is innermost parnthaees
no exponents or multipilcation or division so we add to get 36
[36-32] / 9 * 2
simplify parenthasees/brackets
[36-32] is subtraction, so 4
4 / 9 * 2
division
4/9=0.444444444444444444
0.444444444444*2=0.888888888888888 or 8/9
answer is 8/9 or 0.88888888888 which is none of the options for some reason
