C + 32 = (5/9)F
9(C + 32) = 5F
(9/5)(C + 32) = F
** If they mark you wrong, and try to say the answer is F = (9/5)C + 32 then they shouldn't be teaching math, and you should point out the fact there are no parenthesis around the F - 32 in the given formula.
Answer:
54, 36
Step-by-step explanation:
67+59+x=60*3
126+x=180
x=54
54 cones on Sunday
_____________________________________
180+x=54*4
180+x=216
x=36
36 cones on Monday
