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:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:
(2,−4)
Equation Form: x= 2, y = −4
Step-by-step explanation:
I did the math
okay so the answer is a. and b. since how you put them they are the same. so the answer is -4 x 8
hope this helps
A: The other related equations would be:
K = °C + 273.15
K = °F + 457.87
<em>Note: There are other equations that can be related, these are just ones that I find to be related. This is open to interpretation. </em>
B:
23° C + 273.15 = 269.15 K
C:
300 K - 273.15 = 26.85 °C
300 Kelvins is greater than 25 degrees Celsius.
Answer:
8. x=-5 and y=7
9. x=-2 and y=0
