35% of $12 is $4.20, so the sale price is $12- $4.20 = $7.80
Answer:
It will take 8 years.
Step-by-step explanation:
If the plant is already 14 inches and you want it to grow up to 38, then we subtract 14 from 38 and then divide the answer by 3 because in each year the plant will grow 3 inches, so then you get 8, which is the numbers of years.
38 - 14 = 24
24/3 = 8
first make 5 5/8 a improper fraction so 45/8 and then do the same thing to 2 6/7 so now 45/8- 20/7 and then subtract that to 2/7 and that subtract that by 5/8 to finally get the answer
0^2-4(-2)(3)
0-4(-2)(3)
0-4(-6)
0+24
24
Because the discriminant value is positive, there are 2 real number solutions.
