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

How do i work out 6x+6=0
VMariaS [17]

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

Define a variable, write an equation and solve: An investment increased 30% before taxes. $200 was withdrawn to pay taxes and th
strojnjashka [21]

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! :)

Combine like terms to create an equivalent expression.
svetoff [14.1K]

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
