Step-by-step explanation:
in two months
Decrease of 25%
so you need to do
25%*12 is 3 minutes
Find the difference from 12 minutes
12-3 is 9 minutes.
therefore, his mile time is 9 minutes in two months
The answer is 45 because you multiply 9 and 6
2x^2 + 10x = 0
we can take out x from both terms and we get:
x(2x + 10) = 0
now either x has to be equal to 0 or 2x + 10 has to be equal to zero in order for equation to be equal to 0.
one solution is x=0 as stated above
other is:
2x + 10 = 0
2x = -10
x = -10/2 = -5
Answers are x=0 and x = -5.
(1/2)(1/2)(1/2)(1/2)= 1/16 or 6.25%
60 x 40%
60 x .40 = 24
