Question

Help please word problem...show work please

Answer 1

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

C=
`(5)/(9)`(50-32)
C=
`(5)/(9)`(18)
C= 10
50 degrees fahrenheit is equal to 10 degrees celsius

B) you must solve the equation for F

C=
`(5)/(9)`(F-32)
C/
`(5)/(9)`=F-32
C/
`(5)/(9)`+32=F
F= C/
`(5)/(9)`+32

dividing by a fraction is the same as multiplying buy its reciprocal so it can also be written as

F=
`(9)/(5)`C +32

now you just plug in 50 for the variable C in the new equation

F=
`(9)/(5)`(50) +32
F= 90 + 32
F= 122

50 degrees celsius is equal to 122 degrees fahrenheit

hope this helped!
