Through settlement houses, political machines, and ethnic communities.
Answer:
-42
Step-by-step explanation:
directly means y = kx where k is a constant. you have to first find the constant.
now you have your equation 
so you simply plug in x and find y
There was originally 7.8 liters of water in the pitcher
Answer:
7³
Step-by-step explanation:
when dividing exponents that have the same base, you leave the base as the original (so in this case 7) and subtract the exponents (in this case it would be 9-6). that will be your new base and exponent.
We want to find the greatest common factor of two given expressions.
The GCF is 15*a*b.
The two expressions are:
45*a^3*b^2 and 15*a*b
To find the greatest common factor, we can rewrite the first expression to get:
45*a^3*b^2 = (3*15)*(a^2*a)*(b*b)
Now remember that we can perform a multiplication in any order we want, so we can rearrange the factors to write this as:
(3*15)*(a^2*a)*(b*b) = (15*a*b)*(3*a^2*b)
Then we have:
45*a^3*b^2 = (15*a*b)*(3*a^2*b)
So we can see that 15*a*b is a factor of 45*a^3*b^2, then the GCF between 15*a*b and 45*a^3*b^2 is just 15*a*b.
