Answer:
F = 
Step-by-step explanation:
Given
C = 
( multiply both sides by 9 to clear the fraction )
9C = 5(F - 32) ← distribute
9C = 5F - 160 ( add 160 to both sides )
9C + 160 = 5F ( divide both sides by 5 )
= F
Answer:
16.2
Step-by-step explanation:
Tan(angle)=opposite/ adjacent
Angle= 45
Opposite side= x
Adjacent side =10
Substitute into equation: tan(45) = x/ 10
Rearrange (multiply each side by 10): 10 x tan(45) = x
Then work it out on calculator
Is the question how much it cost per kg?
If so, divide $13 by 1 3/7 kg.
13/(1 3/7) = 13/(10/7) = 13 * 7/10 = 91/10 = 9 1/10
Answer is 9 1/10 dollars per kg.
(Assuming I guessed your question correctly.)
