Answer:
13
4
OR
3
1
4
Step-by-step explanation:
first you work out what is in the brackets
that is
1
3
÷
1
6
to give you 2 as you answer
second step rewrite the whole question replacing two in the place of
1
3
÷
1
6
so you will have
3
4
+
2
−
(
−
1
2
)
thirdly open the brackets with the negative sign outside the bracket that is:
−
(
−
1
2
)
so that you get
+
1
2
(or
1
2
, basically)
lastly rewrite the whole question
so you will have
3
4
+
2
+
1
2
, you add all of them ...
3
4
+
8
4
+
2
4
=
13
4
EXTRA
you can keep that solution, or you can change it from improper fraction to a mixed number
if you use long division,
13
÷
4
=
3
with a remainder of
1
over
4
.
doing this by calculator you get 3.25, which is basically
3
25
100
=
3
1
4

Answer:
<em>12^2 + x^2 = 13^2</em>
Step-by-step explanation:
The student's error was that he didn't use the Pythagorean Theorem correctly

However, the student replaced <em>c</em> with <em>x</em>, which isn't the hypotenuse
The hypotenuse is 13, so <em>c</em> should be 13, not <em>x</em>
