Step-by-step explanation:

so A = 64a +45
(
so B = 108 +a
2A-B=0--> 2(64a+45)-108-a=0--> a =18/127
Answer:
2.33 kg
Step-by-step explanation:
If the baker needs to use 2.327 kilograms of blueberries, we are going to subtract the amount of the packages to the amount he needs and we'll see which is the smallest number.
In the case of 2.3, 2.327 - 2.3 = .027
In the case of 2.42, 2.327 - 2.42 = -0.09
In the case of 2.33, 2.327 - 2.33 = -0.003
In the case of 2.4, 2.327 - 2.4 = -0.07
Therefore, the closest amount to 2.327 is the 2.33 package.
Most people use the decomposition method but i dont know how to do that so i use the Joes method a method similar to decomp. but easier.

Find gcf: None
complet trinomial: 18n^2+57-10
find the product=10(18)
=-180
find the sum =57
-3 and 60 goes into both meaning if you multiply 3 and60 you get -180 and if you add them you get 57.
so (n-3)(n+60)
divide by a in this case it 18
so (n<u>-3</u>)(n+<u>60</u>)
18 18
do not divide. treat it like a fraction so you reduce it to lowest terms
(n<u>-3</u>)(n<u>-3)
</u> 18 10
<u /> at this point its reduced to lowest terms so now you take the deniminator and move it beside the "n"
=(18n-3)(10n-3)
therefore your answer is (18n-3)(10n-3)
I hoped this helped :)
