Answer: I need help with this problem toooo. Does anyone know how to do it?
Step-by-step explanation:
So the sum of 17 and a number x means to add them on one side of the equals sign. The other side would be your 20.
17 + x = 20
If we multiply the inequality n<4 by 3 we get the following:

Now, on the next inequality we have the following:

By transitive property, we have:

therefore, the solution set for m is m<8
0 is 500mg and the numbers above are larger.
Answer:
x = 12
Step-by-step explanation:
10x = 120 original equation
10x/10 = 120/10 divide both sides by 10
x = 12 simplify
Check work:
10(12) = 120
120 = 120 (true)
