One variable is the amount of days. Lets call the amount of days D. Another variable is the amount of pictures left. Lets call this p. In this case, since Emanuel is deleting 20 pictures a day, and he has 745 picture to start with, the equation would be 745- 20D=p.
Answer:
A = 437 mm²
Step-by-step explanation:
The general formula for the area of a triangle:
A =
, where 'b' is the measure of the base and 'h' is the measure of the height
Given the dimensions of the triangle in the picture:
A =
= 437 mm²
The expression that could best describe the statement would be " 40 n + 20

260.
Answer:

Step-by-step explanation:
An equation of a line is given
, where m is the gradient or 
The rise indicates the change in value of y (vertical change in the graph).
The run indicates the change in value of x (horizontal change in the graph).
Let point 1 of the graph be (x,y) = (0,-34) and point 2 be (x,y) = (20,0).
Substitute point 1 into the graph to get the constant c.



∴ The equation of the line is,
