The conversion formula is f = (9/5) c + 32 [ The 95c is very confusing!]
(9/5)c = f - 32
Multiply both sides by 5/9:-
c = (5/9) ( f - 32)
That's option a).
Answer:
Option D
Step-by-step explanation:
we have
-----> equation A
-----> equation B
Solve the system by elimination
Multiply both sides equation A by -1
-----> equation C
Adds equation C and equation B
<em>Find the value of x</em>
substitute the value of y in either equation
The solution is the point (-1,2)
In this problem Option A,B and C are correct
The option D not result in a system with a pair of opposite terms
because
Multiply both sides of equation B by -3
-----> equation C
Multiply both sides of equation A by 5
----> equation D
so
equation C and equation D not have a pair of opposite terms
Answer:
17
Step-by-step explanation:
