From my research, the original equation Fiona wrote was "y = (2/5)x - 5". It also had choices as written below:
x – 5/4y = 25/4
<span>x –5/2 y = 25/4 </span>
<span>x –5/4 y = 25/2
</span>
<span>x –5/2 y = 25/2 </span>
To obtain the possible equation Henry had written, the coefficient of x was removed, and the equation was placed in the form x + y = c. This is shown as follows:
y = (2/5) x – 5
[ <span>y = (2/5) x – 5 </span>] (5/2)
(5/2)y = x - 25/2
x - (5/2)y = 25/2
<span>Therefore, Henry's equation is x – (5/2) y = 25/2.</span>
Yes Johhny is making a valid inference because he settled his inferences based on the votes. <span />
Lets work backwards, he had $5 after it all, and spent $1.25 on a snack, so we add that to the remainder, which is $6.25. then he spent half of that on whatever stuff he likes, so add $6.25 and $6.25, which is $12.50
