Can someone help me how to solve this?

Answer:

x > -5  in the answer


Step-by-step explanation:

(5 - 3x) / 4 < 5

multiplying both sides by 4:-

5 - 3x < 20

-3x < 15

x > 15/-3

x > -5  (Note the inequality sign is flipped because we are dividing by a negative number)

What’s the expression 4m - 17 + 3m - 11
Rina8888 [55]
=4m - 17+ 3m - 11
combine like terms
=(4m + 3m) + (-17 - 11)
=7m - 28

This can be factored/simplified by dividing everything by 7
=7(m - 4)

Hope this helps! :)
