13 × 9w = 13 × 
117w = 5w - 6 + 13
117w = 5w + 7
117w - 5w = 5w - 5w + 7
112w = 7
112w ÷ 112 = 7 ÷ 112

Answer:
Same thing here as the last question, just matching congruent angles.

Answer:
Angle A= 30
Step-by-step explanation:
A triangle has to equal 180 degrees so the first thing you have to do is subtract 180-70. You get 110 so the other two angles in the triangle have to equal 110.
Now you can solve the expression x+40+x+90=110
First combine like terms 2x+130=110
Then subtract 130 from both sides 2x=-20
Then divide by 2 x=-10
Then solve for a -10+40=30
So angle A = 30
Add 8 to one to equal 9. So --> 6x+9=6x.
Or minus 1 from 8 to equal 7. So --> 6x=6x-7.
Then divide both 6's (cancel them out). Which leaves you with either 9 or -7. :)
The answer is 1 I’m pretty sure
