Answer:
A
Step-by-step explanation:
- - Solve:
Start of by simplifying both sides of your problem.
3*2x+3*-7=32
6w+-21=3
6w-21=3
- - Now you need to add 21 to both sides to be able to finish solving.
6w-21+21=3+21
6w=34
- - Final step:
Answer: w=4
If there are 18 students every one of the will pair up with 17 other students throughout the year so the total amount of pairs that can be made is 18x17=306 but since it’s not important if student A is paired with student B or student B with student A we should divide the total amount of pairs by two- 306:2=153 so in total there will be 153 projects finished
