B: 5f = 3c-55, then f = 3c-55/5
Solve: for m; .....
Addition property of equality states that you add same number to both sides of an equation
Add 90 to both sides in , we get;
-mk-90+90 > 85+90
Now, divide both sides by -k.
Also remember, that when you divide or multiply a number in an inequality, you must flip the sign to its opposite.
Therefore, the value of for k≠0.
Solve: 3c-5f=55 for f;
Subtract both sides by 3c we get;
Divide both side by -5 we get;
Therefore, the value of for every c.
A) m < -175/k and B) 3c/5 - 11
A) Add 90 to both sides. -mk > 175.
Next, divide both sides by -k. Because you divide by a negative, don't forget to reverse the sign!
m < -175/k.
B) Subtract 3c from both sides.
-5f = 55 - 3c.
Now multiply both sides by -1/5.
f = 3c/5 - 11
