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!
Answer:
10.5
Step-by-step explanation:
Answer:
144km/hr
288km distance travelled
Step-by-step explanation:
40m/s
= 0.04km/(1÷60÷60)hr
= 144km/hr
distance = speed × time
d = 144 × 2
= 288km
Answer:
no solution
Step-by-step explanation:
Given
2(x + 1) = 2x + 5 ← distribute parenthesis on left side
2x + 1 = 2x + 5 ( subtract 1 from both sides )
2x = 2x + 4 ( subtract 2x from both sides )
0 = 4 ← not possible
This indicates the equation has no solution
