The answer would be 0.05 because the five is in the hundredths place
Solve for x:
x^2 + 10 x + 12 = 36
36 = 36:
x^2 + 10 x + 12 = 36
Subtract 12 from both sides:
x^2 + 10 x = 24
Add 25 to both sides:
x^2 + 10 x + 25 = 49
Write the left hand side as a square:
(x + 5)^2 = 49
Take the square root of both sides:
x + 5 = 7 or x + 5 = -7
Subtract 5 from both sides:
x = 2 or x + 5 = -7
Subtract 5 from both sides:
Answer: x = 2 or x = -12 Thus the Answer is A.
If xy=0
assume that at least x or y=0
3(x-3)=0
therefor
3=0 or x-3=0
3=0 is false
therefor
x-3 mus equal zero
x-3=0
add 3 to both sides
x=3
Answer:
1. 5 hours
2. 4 hours
Reason:
Formula for speed is speed = 
, if you want to find time, then take distance / speed, which will equal to 100 / 20 = 5 hours, and the same with 2.
Answer:
8
Step-by-step explanation:
First, make an expression. If it states that 200 people and 25 tables, we can assume that its a division problem. So,
200/25=?
200/25=8
8 people can sit at a table.
