Answer:
36
Step-by-step explanation:
Using the angle addition postulate
angle 1+angle 2+angle 3=180
Angle 2 is 90 degrees,
Angle 1 is 2x degrees
Angle 3 is 3x degrees
Plug this into equation
Plug 18 into 2x
Answer:
20
400 is 20 square= 20*20
so 20 students in each row
<span>8x + 5 = 35
------------------
Subtract 5 from each side
</span><span><span>8x + 5 - </span>5 </span>= <span>35 - 5
</span><span>8x </span>= <span>30
</span>-----------------------------
Divide each side by the number 8
8x ÷ 8 = 30 ÷ 8
x = 15/4 or 3.75 or 3 3/4
Infinite, and none. Goodbye
