Answer: well it's correct-
Step-by-step explanation: it shows that e equals to 6-x, x would be 3 so then the problem would still be correct (3=|3|) and |3| just equals, well, 3.
Answer:
A <u>bi-conditional statement</u> represents the idea of "if and only if." Its symbol is a 
.
Step-by-step explanation:
We have been given an incomplete sentence. We are supposed to fill in the given blank.
A _______ represents the idea of "if and only if." Its symbol is a .
We know that "if and only if" stands for bi-conditional statement, which represents either both statements are true or both are false.
The symbol represent a bi-conditional statement.
Therefore, our complete statement would be: A <u>bi-conditional statement</u> represents the idea of "if and only if." Its symbol is a .
<span>The total number of hours worked between Ruby, Isaac, and Svetlana, hard-working friends with great names, is 126 and is equal to r + i + s. 126 = r + i + s. The relationships between Svetlana and Ruby's hours can be written as s = 4r. The relationship between Ruby and Isaac's hours can be written as r = i + 6, or i = r - 6. With these equations, we can return to the original equation and substitute for/ replace Svetlana and Isaac's hours so that the whole equation is in terms of r: 126 = (r) + (r-6) + (4r). Simplify this to 126 = 6r - 6 and then again to 132 = 6r and then at last to 22 = r, the number of hours that Ruby worked. Now returning to the other equations, we can plug in that r value to solve for i -- i = 22 - 6, or 16 hours for Isaac -- and for s -- s = 4(22), or a whopping 88 hours for Svetlana. We conclude that Isaac worked for 16 hours, Ruby worked for 22 hours, and Svetlana worked for 88 hours. 88 + 22 + 16 = 126 hours.</span>
Answer:
Power = 120000 watts
Step-by-step explanation:
mass = 2000kg
acceleration = 3m/s²
velocity = 20m/s
Force = mass x acceleration
Force = 2000 x 3 = 6000 Newton
Power = Force x velocity
Power = 6000 x 20 = 120000 watts
Since 1000 watts = 1kilo-watts
Power = 120000 watts or 120 kilo-watts
