Answer:
The number is 21.
Step-by-step explanation:
First you need to solve for n.
So the equation would be 2n = |5n-63|
First you'd subtract 5n from each side, that would give you -3n=|-63|
Then you need to divide each side by -3 to get n=21.
~~~~~
To check, you can just plug 21 back into the equation.
2(21) = |5(21) - 63|
42 = |105-63|
42 = |42|
42 = 42
B.) y=3x
The slope of a given line is defined by <em>y=mx+b</em>, where b is the y-intercept (the point at which the line crosses the y-axis) and m is the slope (rise/run). We see that the y-intercept is 0 (because the line hits the y-axis at 0) and the slope is 3 (rise=3 and run=1, so 3/1=3).
:)
You use additive inverse to combine like terms that are on opposite sides of the equation.
ie.
3x + 1 = 6x -12
You use additive inverse to move -12 to the +1
Answer:
114.31 nautical miles per day
Step-by-step explanation:
Use formula
where S is the distance, t is time and v is rate.
If S=11431 nautical miles and t=100 days, then
