Part a: solve –mk – 90 > 85 for m. show your work. part b: solve 3c – 5f = 55 for f. show your work.

A) m < -175/k and B) 3c/5 - 11

Step-by-step explanation:

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

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
