Answer:
a) 30
b) 144
c) 4
d) 900
Step-by-step explanation:
a) 6 + 24 = 30
b) 6 * 24 = 144
c) 24 ÷ 6 = 4
d) 
C 16 because a is 4 and 4 times 4 is equal to 16
Convert the 1/2 to a number that has a 16 in the denominator
because you can only add or subtract numbers that have the same denominator
so 1/2 = 8/16
the 8 + 5 = 13
so 8/16 + 5/16 = 13/16
therefore your answer is 13/16
Quick answer: 68oF <<<<
A quick way to figure this out is to double the C temperature and add 30, just so you get an estimate.
F ~ 2*20 + 30 ~ 70oF
Now let's use the actual formula
F = 9/5 * C + 32
F = 9/5 * 20 + 32
F = 180/5 + 32
F = 36 + 32
F = 68o
68oC <<<<< answer.
