Can anyone help me with this ?
DanielleElmas [232]

Answer: x=35

Step-by-step explanation:

There are 720 degrees total in a hexagon. So, all of the angles should add up to that. Write out the equation

720= (4x-5)+(117)+(3x-3)+(3x+6)+(118)+(4x-3)

720=14x+230

490=14x

x=35

hope this helped you:)

A pair of equations is shown below: y = 7x − 8 y = 5x − 2 Part A: Explain how you will solve the pair of equations by substituti
Alexus [3.1K]
Part A) If would probably be smart to use substitution because y is already solved for, so we can substitute the value of y as a function of x into the other equation.
y=7x-8
y=5x-2

7x-8=5x-2
    +8     +8
-----------------
7x=5x+6
-5x  -5x
----------------
2x=6
/2   /2
-----------
x=3

y=7x-8
y=21-8
y=13

Part B) The lines will intersect at point (3, 13), because idk it just makes sense
