In the expression, there are 3 terms.
3x and 4x are like terms because the variables are identical.
Also, we have a constant term which is -3.
Answer:
Step-by-step explanation:
- 162 total guests.
- 3 servers
Let the number of guests the second server helped be x.
then the first server helped 3x
then the third server helped [(3x)*2] = 6x
Equation in total:
6x + 3x + x = 162
10x = 162
x = 16.2
- First server helped: 3 * 16.2 = 49 guests
- Second server helped: 16 guests
- Third server helped: 6x = 6(16.2) = 97 guests
First, solve within the parentheses. 18/6=3. Now solve the multiplication and division 1/2x6=3. The equation is now 3+9-3. Add and/or subtract from left to right. 3+9=12. 12-3=9. The answer is 9.
Answer:
12n
Step-by-step explanation:
The equation to solve this is $1,200+a=b, with a being the cost of the amount of cold cuts being transported and b being the total cost for the truck and the meat.
