Answer:
The answer would be 122.4
because 9 x .6 = 5.4
and 9 x 6.5 = 58.5
and 58.5 x 2 = 117
117+5.4=122.4
The answer is -13.48 – 6.58í.
I mean bases on the question this is the right answer. If not, can you clarify.
<span>(a/20)+(4/15)=(9/15)
a/20 = </span>(9/15)-<span>(4/15)
</span><span>a/20 =5/15
</span><span>a/20 =1/3
a=20/3
</span>
