Two-fifths time a plus a over 2 equals a minus 2 will be a=20
Step-by-step explanation:
We have to find a, by first writing the verbal expression into an arithmetic form as,
Two fifths times a = (2/5)a
a over 2 = a/2
a minus 2 = a-2
(2/5)a + (a/2) = a-2
We have to take LCM on LHS as 10.
(2×2 /5×2)a + (a×5 /2×5) = a-2
(4a/10) + (5a/10) = a-2
Moving 10 to the other side, we will get,
4a+ 5a = 10(a-2)
9a = 10a -20
Grouping terms we will get,
10a - 9a = 20
a = 20

5. if a=b, then b=c
I think #2 is correct ,but I don't know about the others
Options 2 and 5 i.e., and are the correct statements such that .
Ratio is the mathematical indication that tells how many times one number contains another.
Reciprocate the given proportion both sides-
So, option 2 is correct.
Now, if then, the proportion will become-
So, option 5 is correct.
Thus, options 2 and 5 are the correct statements.
