Answer:
9
Step-by-step explanation:
3-sqrt(x)=0 should be rewritten as 3 = sqrt(x) or sqrt(x) = 3.
To obtain the value of x that satisfies this equation, square both sides:
x = 3^2, or x = 9.
Answer:
No her calculations do not make sense because the area of the smaller walls together is 234 and not 244 the total square feet of the windows and doors are also wrong. She should also subtract the doors and windows from the total so she doesn't over spend on paint. Her answer is correct just the way of finding it is wrong.
Step-by-step explanation:
Walls total sqft: (2(13ft)(9ft))+(2(16ft)(9ft))=234ft²+288ft²=522ft²
Doors+Windows total sqft: ((2(20ft)+(2(15ft))=60ft²+30ft²=90ft²
Total amount of paint needed: 522ft²-90ft²=432ft²
Amount of gallons needed remains the same
Hopefully this makes sense.
Answer:
The answer is x=-16.
Step-by-step explanation:
I cant give you the step by step explanantion but I can later! I hope this helps thoough!
The nearest hundred would be 400
Answer:
See explanation below.
Step-by-step explanation:
Let's say,
x = number of tokens required to play one game of ping pong
y = number of token required play one game of pinball
Using the data given, the system of equations are:

Solving the system of equations using substitution method will give us:

So, one game of ping pong required 1 token, whereas one game of pinball required 4 tokens.
