I think x=1
First you have to get rid of an variable on one side so you so 2x-3x than you are left with 4=x+3 than you want to get the variable alone so you subtract 3 from 4 than you are left with 1=x
11 + 4b = 8b - 13
11 + 4b - 8b +13 = 0
4b = 24
b = 6
Answer:
Step-by-step explanation:
42 = 32 - 6f - 4f
42 = 32 - 10f
10 = -10f
-1 = f
f = -1
The answer is A.
B is incorrect because she selected 3 from each state, not 150 all from one state.
C is incorrect because random sampling is good. It helps eliminate group biases in polling. C suggests that random sampling is a bad thing.
D is incorrect becasue once again, she selected 3 from each state, not 150 from one state.
because it's a square, all of the sides are equal length so you can do
4(6x+3)
which equals 24x+12
