Step-by-step explanation:
cross multiply all equations seperately
1,n=63
2.n=24
3.n=19
4.n=20
Answer:
you have to round down because if you round up she wouldn't have enough money. And you can't buy half a book.
Step-by-step explanation:
1) As we can see this is a Linear Equation written in the Slope-intercept form:
Note that "m" stands for the slope of the line, i.e. the measure of how steep a line is.
In the given equation, we can state that the slope is always accompanying the "x" therefore, the slope is m= 7
2) In addition to this, the y-intercept also called the Linear Coefficient is given by the letter"b" and represents the y-coordinate that the graph intercepts. Thus the y-intercept is -6
So we can state the following as the answers:
And that is the answer
Answer:
b
Step-by-step explanation:
Answer: -30r + 15
Step-by-step explanation:
first, we multiply the parenthesis by 20.
-20 x 1.5r + 20 x 0.75
then, we multiply/calculate.
-30r + 15
