hi i would really appreciate some help solving this question simultaneously:
Find A and B such that
x-11/(x+3)(2x-1)= A/x+3 + B/2x-1
Multiply both sides by (x+3)(2x-1) to get rid of the fractions.
We end up with this:
(x-11) = A(2x-1) + B(x+3)
You can solve for A and B more easily now.
I hope this helps and is what the problem was asking.
how can estimation help you deside if the exact product for 7 times $74.65 is greater or less than $600?
To estimate whether the exact product of 7 times $74.65 is greater or less than $600, you can round the numbers involved and perform a quick calculation.
First, let's round $74.65 to the nearest whole number, which is $75. Then, multiply $75 by 7: 75 x 7 = 525.
Since 525 is less than 600, we can estimate that the exact product of 7 times $74.65 is less than $600.
Estimation is a useful tool to quickly assess the magnitude or general size of a value without having to perform precise calculations. However, keep in mind that estimation provides an approximation and may not be completely accurate.
