Given that the sum of the three interior angles of a triangle is equal to 180°, we can formulate the following equation:
2x + 1 + 2x + 93 = 180
4x + 94 = 180 (Adding like terms)
4x = 180 - 94 (Subtracting 94 from both sides of the equation)
4x = 86
x= 86/4 (Dividing by 4 on both sides of the equation)
x= 21.5
Replacing in the angles we have:
Angle 2x + 1 ---> 2(21.5) + 1= 44
Angle 2x ---> 2(21.5) = 43
The angles of the triangle are 43, 44 and 93.
Answer:
Multiplication properly of equality
Hey there!
Geometric sequences have a common ratio. In this case, we can see that it is always multiplied by -3.
The formula for a geometric sequence is starting number multiplied by the quantity of the the common ratio to the power of the term number in the sequence minus 1.
In our case, we will have 2*-3^11-1. We will now simplify this.
2*-59049= -118098
Therefore, our answer is -118098.
I hope this helps!
Answer:
The answer is c and we'll use c to get the actual answers.
A) n + q = 104
B) .05n + .25q = 22 we'll multiply B) by -4
B) -.2n -1q = -88 then we add A)
A) n + q = 104 which equals
.8n = 16
n = 20 nickels
q = 84 quarters
20 nickels = $1
84 quarters = $21
