Step-by-step explanation:
2x + 2x + 2 = 4x + 2 <em>combine like terms</em>
4x + 2 = 4x + 2 <em>subtract 4x from both sides</em>
4x - 4x + 2 = 4x - 4x + 2
2 = 2 TRUE
<h2>CONCLUSION:</h2><h3>This equation has an infinitely many solutions. The solution to this equation is any real number.</h3>
Answer:
The party will cost 28.125 dollars.
Step-by-step explanation:
Because to find how much each person costs you would have to take 22.50 divided by 4 to get 5.625, then do 5.625 times 5 to get 28.125 as your answer.
We can use the formula length x width x height. Substitute in the numbers for words and you get:
14 x 14 x 19...
...which equals 3724cm^3.
Hope I helped! Sorry if I'm wrong.

The very top line in increased by 10%
Step-by-step explanation:
(25x+8)°+(9x+2)°=180--->(1)(sum of angles on a straight line
(7y+5)°=(9x+2)°------------->(2)(vertical angles)
25x°+8°+9x°+2°=180°
34x°=170°
x=5°
from equation (2) substitute for x=5°
7y°+5°=9x°+2°
7y°+5°=9(5)°+2°
7y°=47°-5°
7y°=42°
y=6°
(x, y)=(5°,6°)
