The angle next to the angle 5x is 180 - 5x
All angles sum to 360
(6x - 58) + (2x + 4) + (180 - 5x) = 180
3x + 126 = 180
3x = 54
x = 18
For question 10, sum of angles in pentagon is 540 degrees
x + 105 + 85 + 114 + 126 = 540
x + 430 = 540
x = 110
Answer: X= -1
Step-by-step explanation: In this equation you want to solve for "x"
You subtract 6-6=0 leaving "x" by itself. So the equation will look like this: 6x= -6
After this you want to divide by 6 to one side and to the other equaling "x" as -1
Answer:
$1307.69
Step-by-step explanation:
Let the original investment be x.
Note that a 30% increase in a value is equal to multiplying a value by 130% and a withdrawal is to take out money. The final amount is $1500. Let’s write the equation with the information we have.
Equation:
130%x - 200 = 1500
(130/100)x = 1700
x = 1700(100/130) = $1307.69
I hope this helps! :)
Answer:
113.143 cm²
Step-by-step explanation:
Radius=diameter/2=12/2=6 cm
Now
Area of a circle=πr²
=(3.16)(6)²
=(3.16)(36)
=113.143 cm²
Answer:
2/5m - 1/5
Step-by-step explanation:
distribute the 2 to every term in ()
2(1/5m-2/5) = 2/5m - 4/5
now you have 2/5m -4/5 +3/5
combine like terms variables with variables, non- variables with non-variables. -4/5 + 3/5 = 1/5
2/5m - 1/5
