F = 9/5C + 32
Subtract 32 to both sides:
F - 32 = 9/5C
Divide 9/5 to both sides or multiply by its reciprocal, 5/9:
5/9(F - 32) = C
Simplify:
C = 5/9F - 160/9
Answer:A
Step-by-step explanation:
the answer is A
Answer:
A, yes.
Step-by-step explanation:
63:60, 21:20:
The difference between 60 and 20 is *3. If you do that to 21, you get 63. So a , yes.
Find the horizontal and vertical distance between the points. First, subtract y2 - y1 to find the vertical distance. Then, subtract x2 - x1 to find the horizontal distance.
63 = 9k
divide by 9 on each side to get k by itself
k = 7
