Answer:
b=4
Step-by-step explanation:
4b + 5 = 1 + 5b
Subtract 4b from each side
4b-4b + 5 = 1 + 5b-4b
5 =1+b
Subtract 1 from each side
5-1 = 1-1+b
4 =b
Answer:
d = 363/8
Step-by-step explanation:
Let's write this as a fraction:
8 1/4 2
------------- = -------
d 11
One way in which this could be approached would be to interchange 'd' and '2:'
8 1/4 d 33 d
------------- = ------- or -------- = ---------
2 11 4(2) 11
Multiplying both sides by 11 isolates d:
33(11) 363
-------- = d, or d = ----------
8 8
