Start with your given equation - F=9/5C+32
Subtract 32 from both sides - F-32=(9/5) degrees C
Multiply both sides by 5 - 5(F-32)=9C
Divide both sides by 9 to isolate C - (5/9)(F-32)=C
Answer - C=(5/9)(F-32)

Answer:
13. b. 4 + 5x = 29; $5.
14. c. 74 + w = 3w + 6; 34 pounds.
15. b. $42.5.
Step-by-step explanation:
13. 4 + 5x = 29
5x = 29-4 = 25
x = 5.
14. 74 + w = 3w + 6
68 = 2w
w = 34.
15. Let x be the money he got last year. Then:
2x + 5 = 90
2x = 85
x = $42.5.
Answer:
$0.4
Step-by-step explanation:
