Mathematics
1 answer:
Zinaida [17]2 years ago
6 0

Answer:

45

Step-by-step explanation:

9, 13, 17, 21, 25

We are adding 4 each time

9+4 = 13

13+4 =17

17+4 = 21

The common difference =4

a1 = 9

The formula is

an = a1+d(n-1) where n is the term number

an = 9+4(n-1)

We want the 10th term

a10 = 9+4(10-1)

     = 9+4(9)

    = 9+36

   = 45

How would I do this with working ?

You Just want to get Fahrenheit alone on one side of the equal sign. Your  teacher forgot to use parenthesis. The correct equation for Celsius to Fahrenheit is: C= \frac{5}{9} (F-32)

Which will give you a completely different answer.... F = \frac{9}{5} C + 32

****

We will solve it using what is given:

C = (5/9)F - 32

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.
