So we know that the bacteria grows 3x as much every ten minutes. From this we know that it'll be 3 mm in 20 minute. Continuing the pattern, we can figure out that in 40 minutes the bacteria will be 81 mm.
The pattern: 10min - 3 20min - 9 30min - 27 40min - 81
Answer:
x = -4, y = -6
Step-by-step explanation:
-x+2y = -8
3x-y = -6
x = 2y+8
3(2y+8) - y = -6
6y + 24 -y = -6
5y = -30
y = -6
x = 2(-6)+8 = -12+8 = -4
x = -4, y = -6
5 less than the number x = (x - 5)
Product of 12 and that : 12(x - 5) is = 45. Is is represented by the = sign.
12(x - 5) = 45
Option (c).
