3 + x/2 = 7
x = (7-3)*2 = 8 = the number
I think it would be A. 9.6. I'm completely sure on that one.
We are given with an equation in <em>variable y</em> and we need to solve for <em>y</em> . So , now let's start !!!
We are given with ;
Take LCM on both sides :
<em>Multiplying</em> both sides by <em>10</em> ;

Can be <em>further written</em> as ;
Transposing <em>6y </em>to<em> LHS</em> and <em>150</em> to<em> RHS </em>


Answer:
a
Step-by-step explanation:
6^2+8^2=100
