162 plants, if 60% of the plants live you can set it up like this: 60/100 = X/270, to find X, you cross multiply and divide by 100
Answer:
important, valuable, nice,
X=the number we have to find.
This expression "2(x+9)" is when the sum of a number and nine is doubled.
If the result is seven less than the number, we will have: x-7
We can suggest the following equation:
2(x+9)=(x-7)
2x+18=x-7
2x-x=-7-18
x=-25
answer: the number would be: -25.
