Answer:
8
Step-by-step explanation:
1) let’s take the original number as “x”
So
3x=28-0.5x
Lol don’t worry I’ll show you how I got that
So it says 3 times a number. That tells me my number, X is multiplied by 3 so I have
3x so far
Next it says “is equal to”, this tells me my number 3x is equal to something so I have this now:
3x=
After that it says “half of a number” so I know I will have 0.5x subtracted from 28. Since it says subtracted from 28 that means my number will be subtracted from 28, not the other way around so
3x=28-0.5X
Now I can solve this by bringing “-0.5” to the left.
3x+0.5x=28
3.5x=28
Divide both sides by 3.5 and
X=8
The expression is simply -2-18. When you have an expression like this, just put the together and the put a box around the first number don't forget the sign, and then the next put one around the sign and the number. If this doesn't make any since, sorry we just started this unit
