Okay so we know that 3/5 of the conductors club went on the last camping trip. We also know that 3/5 of the club is equal to 39 people. All we have to do is find the last 2/5 and add it to our 3/5 to get the answer:
To find how much each 1/5 is, divide 39 by 3. This will give us 13. Then we multiply it by 5, because there are five parts. This gives us 65. So the answer is 65
30 + 40 1- 40 = 69

Answer:
b)-9,2
Step-by-step explanation:
x^2+7x-18=0
x^2+9x-2x-18=0
x(x+9)-2(x+9)=0
(x+9)(x-2)=0
therefore
x=-9
x=2
