Help! The sum of 6 consecutive even numbers is 126 what is the answer?

1 answer:

8 0

6 consecutive even numbers
First x
Second x+2
Third x+4
Fourth x+6
Fifth x+8
Sixth x+10

126=x+x+2+x+4+x+6+x+8+x+10
126=6x+30
Subtract 30 from both sides
96=6x
Divide both sides by 6
x=16

Fourth x+6=16+6=22

Answer

x=29

Step-by-step explanation:

Okay we know that the sum of all angles in a triangle is 180, so all we have to do is add them up first

(x+17)+(2x+5)=3x+22

(3x+22)+(3x-16)=6x+6

okay so we now know that 6x+6=180

subtract 6 on both sides 6x=174

then divide by 6 to get x=29

hope this helps!
