Question

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)

Answer 1

Part A:
-mk-120 > 95
-mk > 215
Divide both sides by -k
Since we are dividing by a negative, the inequality sign flips
m < 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 2

A). Value of m is
`m<(-215)/(k)`

B). Value of f is
`(2c-45)/(9b)`

Explanation:

A).

we have to find: value of m

consider,

-mk - 120 > 95

-mk > 95 +120

-mk > 215

`-m>(215)/(k)`

`m<(-215)/(k)`

B).

We have to find: value of f

we have,

2c - 9fb = 45

-9fb = 45 - 2c

`f=(45-2c)/(-9b)`

`f=(2c-45)/(9b)`
