Step-by-step explanation:
Answer:
x=8
z=132
Step-by-step explanation:
We know that 6x and 4x+16 are vertical angles, so they are equal
6x= 4x+16
Subtract 4x from each side
6x-4x = 4x-4x+16
2x =16
Divide each side by 2
2x/2 =16/2
x =8
We also know that 6x and x form a straight line
6x+z = 180
6(8) + z =180
48+z =180
Subtract 48 from each side
48-48 +z =180-48
z = 132
Answer:
16
Step-by-step explanation:
15x = 240 x stands for number of students at 1 table
To solve this we divide by 15 both sides for the "x" to remain alone on one side of the equality sign.
(15/15) x = 240/15
So, x = 16.
