Answer:
She needs to number each plant 1–60 and randomly select 10 plants
Step-by-step explanation:
So first you have a -(x-20). The negative distributes to both terms so you are left with -x+20. Combine that with the rest of your statement:
-x+20-2x-16 now you should bring the x's together and the numbers together
-x-2x+20-16 and then solve!
-3x+4 that's it! :)
Answer:
0.61 or 8.79
Step-by-step explanation:
h = 47t − 5t²
27 = 47t − 5t²
5t² − 47t + 27 = 0
Quadratic formula:
t = [ -b ± √(b² − 4ac) ] / 2a
t = [ -(-47) ± √((-47)² − 4(5)(27)) ] / 2(5)
t = (47 ± √1669) / 10
t ≈ 0.61 or 8.79
