Part A: Solve -mk - 120 > 95 for m. Show your work. 4 points)
Part B: Solve 2c - 9fb= 45 for f. Show your work. (6 points)

Respuesta :

Part A:
-mk-120 > 95
-mk 
> 215
Divide both sides by -k
Since we are dividing by a negative, the inequality sign 
flips
< 215/-k

Part B: 
2c-9fb = 45
Subtract 2c from both sides
-9fb = 45-2c
Divide both sides by -9b
f = (45-2c) / -9b

Answer:

A). Value of m is [tex]m<\frac{-215}{k}[/tex]

B). Value of f is [tex]\frac{2c-45}{9b}[/tex]

Step-by-step explanation:

A).

we have to find: value of m

consider,

-mk - 120 > 95

-mk > 95 +120

-mk > 215

[tex]-m>\frac{215}{k}[/tex]

[tex]m<\frac{-215}{k}[/tex]

B).

We have to find: value of f 

we have,

2c - 9fb = 45

-9fb = 45 - 2c

[tex]f=\frac{45-2c}{-9b}[/tex]

[tex]f=\frac{2c-45}{9b}[/tex]
