Answer:
I'm pretty sure the answer to number one is 12g.
Step-by-step explanation:
To combine like terms, you combine all of the same variables.
For example, if you have 5x+7y+5x, you would combine like terms to make 10x+7x.
So for your first problem, we know that the combined like term is 15g. We know that one of the numbers combined was 3g. With that knowledge, you can subtract 15g-3g and get 12g.
I hope this makes sense, and helps you answer your other questions!
Answer:
x=12
Step-by-step explanation:
x^9=12^9
power of 9 cancel eachother at both sides of equation.
so
x=12
For 44- 3x-14=2x+10. So x=24
For 45- 6x=90. So x=15
For 46- 7x+5=180. So x=2
