|a-7|=3,|2b-2|=10 what is the value of b/a
Read Solution (Total 5)
-
- b/a=3/5, 3/2, -2/5, -1
|a-7|=3 => a=10 or 4
|2b-2|=10 => b=6 or -4
Hence b/a=6/10=3/5 or 6/4=3/2 or -4/10=-2/5 or -4/4=-1 - 6 years agoHelpfull: Yes(14) No(0)
- it would be 3/5 as mod of a-7=3 give ous the value of a as 10 and the mod of 2b-2=10 gives ous the value of b as 6 so value of b/a=3/5

- there are four possible solution
-1,-5/2,2/3,3/5 - 6 years agoHelpfull: Yes(1) No(0)
- 4 possible solutions:
a=10,4
b=6,-4
So, b/a=2/5,-1,3/5,3/2 - 6 years agoHelpfull: Yes(0) No(1)
- a-7=3 means 10-7=3 in here value of a=10
2b-2=10 means 2*6-2=10 in here value of b=6
b/a equl to 6/10 or 3/5
because a=10, b=6 - 6 years agoHelpfull: Yes(0) No(0)
