Y=2x+320
x being the number of years and 320 being the initial population of mice
Work out the top subtraction first:
3/9 - 8/12
= 1/3 - 2/3
= 1/3
and the bottom part:-
3/8 * 2 = 6/8 = 3/4
so now we divide -1/3 by 3/4
= -1/3 * 4/3 = -4/9
Answer:
8x - 6 = x + 9 : Given
7x - 6 = 9 :Subtraction property of equality
7x = 15 : Addition property of equality
x = 15/7 : Division property of equality
x = 2.143
Step-by-step explanation:
Match the properties with the steps to solving the following equation.
(8x - 6) = x + 9
8x - 6 = x + 9 : Given
8x - x - 6 = x + 9 - x
7x - 6 = 9 :Subtraction property of equality
7x - 6 + 6 = 9 + 6
7x = 15 : Addition property of equality
7x/ 7 = 15/7
x = 15/7 : Division property of equality
x = 2.143
Answer:
The probability of hitting an odd number three times is 3.375 times more than the probability of hitting an even number three times..
Step-by-step explanation:
Probability of hitting an odd number = 3/5
Probability of hitting an odd number = 2/5
Probability of hitting an odd number three times = (3/5)^3
Probability of hitting an odd number three times = (2/5)^3
Now divide (3/5)^3 by (2/5)^3 we get:
(3/5)^3 / (2/5)^3
(3)^3/(2)^3
27/8 = 3.375
The probability of hitting an odd number three times is 3.375 times more than the probability of hitting an even number three times..
