To solve this question simply break down the variables and numbers one at a time.
Here the word a number can be used to describe any number so let’s call that a variable x.
Increased would be addition in mathematics.
Next put everything together.
5x + 6 = -2
5x = -8
X = -8/5.
This is the value of x
Let x= second number
x-1= first number
2x= 4(x-1) + 26
2x= 4x -4 + 26
2x -4x= 22
-2x= 22
(-1)(-2x)=22(-1)
2x= -22
x=-11 (second number)
-11-1= -12 (first number)
Y = -x + 4.....so sub in -x + 4 in for y in the other equation
x + 2y = -8
x + 2(-x + 4) = -8
x - 2x + 8 = -8
x - 2x = -8 - 8
-x = -16
x = 16
y = -x + 4
y = -16 + 4
y = - 12
one solution (16,-12)
Answer:
ok........
Step-by-step explanation:
Area of a circle = πr²
--------------------------------------------------------
Area of the archery target :
--------------------------------------------------------
Area of the archery target = 9²π
Area of the archery target = 81π
--------------------------------------------------------
Area of the bull's eye :
--------------------------------------------------------
Area of the bull's eye = 3²π
Area of the bull's eye = 9π
--------------------------------------------------------
Area outside the bull's eye :
--------------------------------------------------------
Area of the target outside the bull's eye = 81π - 9π
Area of the target outside the bullseye =72π or 226.19 in²
--------------------------------------------------------
Answer: 226.19 in²
--------------------------------------------------------
