6x³y + 6xy − 12x² − 12 = 6(xy-2) * (x²+1)
(x²+1) is a factor of 6x³y + 6xy − 12x² − 12
Answer:
The amount invested at 4% was $600
The amount invested at 7.5% was $3,600
Step-by-step explanation:
Let
x ----> the amount invested at 4%
$4,200-x -----> amount invested at 7.5%
we know that
The total interest earned is equal to the interest earned by the amount invested at 4% plus the interest earned by the amount invested at 7.5%
Remember that
so
The linear equation that represent this situation is
Solve for x
therefore
The amount invested at 4% was $600
The amount invested at 7.5% was $3,600
Each straw is 4-1/8 inches long.
You have one gigantic piece of straw material, 123-3/4 inches long.
How many straws can you cut it up to make ?
===> (123-3/4) divided by (4-1/8) straws.
Each one costs $0.015 to make.
So, once you find the number of short straws you have,
multiply
===> (the number of short straws) x ($0.015) .
That'll tell you how much it costs to make all of them.
Now you know how to do it on your own.
If you don't get 30 straws and $0.45 , please try again.
Answer:
447.44 is your final answer
Step-by-step explanation:
680 x 0.3 = 204
680 - 204 = 476
476 x 0.06 = 28.56
476 - 28.56 = 447.44
447.44 is your final answer.
