Answer:
x = -3
Step-by-step explanation:
You will have to distribute first
7 -2x -11 + 9 -3x = 20
Then, combine you like terms
-2x -3x = -5x
7 -11 +9 =5
Then you write it as an equation
-5x +5 = 20
Next you will want to have x by itself which means you have to get rid of the 5 by substracting 5 on each side (opposite of addition is substraction)
-5x = 15
Then you divide each side by -5 ( opposite of multiplication is division)
x= -3
Hope this helped :D
Answer:
order is
αb<αc<αa
Step-by-step explanation:
in a )
number 4 and number 12 are showing 3 bullets while number 7 and 9 showing 2 bullets hence
standard deviation for a=3-2=1
in b)
number 4 ,7,9 and number 12 are showing 2 bullets while number 3 and 13 showing 1 bullet hence
standard deviation for a=2-1=1
in c)
number 4 ,7,9 and number 12 are showing 2 bullets while number 5 and 11 showing 1 bullet hence
standard deviation for a=2-1=1
order isαb<αc<αa

Answer:
575.4 sq inches
Step-by-step explanation:
you can divide this shape into:
13 x 13 square
trapezoid with bases of 13 and 30 with a height of 20
semi-circle with radius of 15
A(square) = 169
A(trapezoid) = 53
A(semi-circle) = 353.4
