#11 is 2 ounces because there are 16 ounces in 1 pound and if u add all the #rs you get 32, divide by 16 and u get 2.
#12 is 10 ounces because when u add the #rs up u get 54. u subtract that from 64 because that's how many ounces are in 4 pounds, so ur answer is 10
So we have the equations:
y - 4x = 2 --- equation 1
5y - 2x = 1 --- equation 2
(equation 2) * 2
10y - 4x = 2 --- equation 3
(equation 2) - (equation 3)
-9y = 0 so y= 0 and thus x = -1/2
Hope that helps!
8ab-2b+ab-b
8ab+ ab= 9ab
-2b-b= -3b
Answer: 9ab - 3b
4-1/n^3
I hope this helps.
Have a "AWESOME" day. :)
we know that A has 60% of salt, so if way we had "x" amount of ounces of A solution the amount in it will be 60% of "x", or namely (60/100)*x = 0.6x.
Likewise for solution B if we had "y" ounces of it, the amount of salt in it will be (75/100) * y or 0.75y, thus
