Answer:
$936.32
Step-by-step explanation:
To solve this problem we need to find the remaining 12% of money our neighbor has saved since 88% was $836. To do this, we simply multiply $836 by 12%. Remember to change 12% into its decimal form (12% -> 0.12).
$836 x 0.12 = $100.32
Now, our last step is to add $100.32 to $836.
$836 + $100.32 = $936.32
Our answer is $936.32.
Answer:
x=3.414 and x=0.59 is the desired answer.
Step-by-step explanation:
We are given a quadratic equation as : 
on dividing both side by 2 we have the equation as
on solving for the roots of the equation using the quadratic formula we get that 
and 
x=2+1.414 and x=2-1.414
Hence , x=3.414 and x=0.586≈0.59.
Answer:
x = -5
Step-by-step explanation:
2x-3+3x= -28
combine like terms
5x -3 = -28
add 3 to each side
5x-3+3 = -28+3
5x = -25
divide each side by 5
5x/5 = -25/5
x = -5
Answer:
b: 10% decay
Step-by-step explanation:
Expressed as a percentage change, the growth is usually the value of the base of the exponential function after 1 has been subtracted. That result is expressed as a percent:
0.9 - 1 = -0.10 = -10% . . . . . 10% decay
_____
The "t/12" exponent means this is the decay that is experienced over 12 units of time. This might be the annual decay, where t is expressed in months, for example.
