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

C=\frac{5}{9}(50-32)
C=\frac{5}{9}(18)
C= 10
50 degrees fahrenheit is equal to 10 degrees celsius 

B) you must solve the equation for F

C= \frac{5}{9}(F-32)
C/\frac{5}{9}=F-32
C/\frac{5}{9}+32=F
F= C/\frac{5}{9}+32

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

F=\frac{9}{5}C +32

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

F= \frac{9}{5}(50) +32
F= 90 + 32
F= 122

50 degrees celsius is equal to 122 degrees fahrenheit

hope this helped!

f(x) × g(x)

= 11(123x - 40) ← distribute

= 1353x - 440

Substitute x = - 4 into the product

3 (6+3n) = 5n + 18 + 3n
amid [387]

Answer:

n = 0

Step-by-step explanation:

Multiply parenthesis by 3 and get:

1.) 18 + 9n = 5n + 18 + 3n

Then cancel the equal terms:

9n = 5n + 3n

Collect like terms:

9n = 8n

Move variable to the left:

9n - 8n = 0

n + 0

Plugin the value of 0 into x:

3 (6 + 3 x 0) = 18

5 x 0 + 3 x 0 + 18 = 18

*If the plugged in value have the same result than the answer is correct because 18 + 18.
