100x12= (10x12)+(10x12)+(10x12)+(10x12)+(10x12)+(10x12)+(10x12)+(10x12)+(10x12)+(10X12)= 700
This equation involves no x variable, so I assume you want to solve this for D.
First of all, you can divide both sides by 0.785 to get
Since the right hand side is positive, the equation make sense (otherwise we would be asking a square, i.e. a positive number, to equal a negative number). So, we can extract the square root from both sides:
Step-by-step explanation:
y = 5x - 3 is in slope-intercept form.
The slope of this given line is 5,
=> Parallel line will also have slope 5.
We have y = 5x + c, where c is a constant.
When x = 4, y = 7.
=> (7) = 5(4) + c, c = -13.
Therefore the answer is y = 5x - 13.
