Answer:
C = F - 32 /(9/5)
Step-by-step explanation:
F = (9/5)C + 32
Subtract 32 from both sides
F - 32 = (9/5)C + 32 - 32
F - 32 = (9/5)C
Divide both sides by (9/5)
F - 32/(9/5) = (9/5)C/(9/5)
F - 32/(9/5) = C
C = F - 32 /(9/5)
The answer should be 31. You add 5, and 6 together which gives you 11. You take 42 - 11, and your answer is 31. Hope this helps. :)
Answer:
Step-by-step explanation:
total cost = tickets( c) +50
1400 = 4 (c) + 50
1350 = 4 (c)
337.50 = c
Answer:
3 m4 • sqrt(2m)
Step-by-step explanation:
STEP 1: Factor 18 into its prime factors
18 = 2 • 32
To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.
Factors which will be extracted are :
9 = 32
Factors which will remain inside the root are :
2 = 2
To complete this part of the simplification we take the squre root of the factors which are to be extracted. We do this by dividing their exponents by 2 :
3 = 3
At the end of this step the partly simplified SQRT looks like this:
3 • sqrt (2m9)
STEP 2: Rules for simplifing variables which may be raised to a power:
(1) variables with no exponent stay inside the radical
(2) variables raised to power 1 or (-1) stay inside the radical
(3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:
(3.1) sqrt(x8)=x4
(3.2) sqrt(x-6)=x-3
(4) variables raised to an odd exponent which is >2 or <(-2) , examples:
(4.1) sqrt(x5)=x2•sqrt(x)
(4.2) sqrt(x-7)=x-3•sqrt(x-1)
Applying these rules to our case we find out that
SQRT(m9) = m4 • SQRT(m)
