A) you must plug in 50 for variable F and solve for C
C=

(50-32)
C=

(18)
C= 10
50 degrees fahrenheit is equal to
10 degrees celsius B) you must solve the equation for F
C=

(F-32)
C/

=F-32
C/

+32=F
F= C/

+32
dividing by a fraction is the same as multiplying buy its reciprocal so it can also be written as
F=
C +32
now you just plug in 50 for the variable C in the new equation
F=

(50) +32
F= 90 + 32
F= 122
50 degrees celsius is equal to
122 degrees fahrenheit
hope this helped!
Number 1 is B and number 2 I belive is C. I hope I'm rightt, and I hope this helps.
Answer:

Answer:
81.5, 9, 180
Step-by-step explanation:
28.
c=9
9x9=81
a=1/2
81+1/2=81.5
29.
9x1/2=4.5
4.5x2=9
30.
15x15=225
9x5=45
225-45=180
hope this helps!!!
The answer would end up being 0.01323
