Answer:
16
Step-by-step explanation:
First, simplify by finding the absolute values:
2|-9| - |-2|
2(9) - (2)
Then, simplify this by multiplying 2 and 9:
18 - 2
= 16
So, the answer is 16
5 times amount of people has to be bigger than 2112
5(133+v)≥2112
distribute
665+5v≥2112
minus 665 from both sides
5v≥1447
divide both sides by 5
v≥289.4
yo can't have 0.4 volunterer
v≥290
has to have at least 290 volunteers
