4x = 5x -12
4x - 5x = 5x - 5x - 12
-x = -12
x = 12
Lengths of corresponding sides of similar polygons are in proportion.
That means that 2 is to 3 as 7 is to x where x is the length of the side of the other
triangle.
2/3= 7/x
2x = 21
x = 21/2 = 10 1/2
Answer: b) 10 1/2
Step-by-step explanation:
Since the first coordinates are both (0,0) it implies that the line passes through the origin.
The slope of the line is therefore 5/8
The equation:
y-0=5/8(x-0)
y=5/8x
C. $1,536.
Multiply 138.50 by 36. (4,986)
Then, subtract 4,986 by 3,450.
Is there anything that explains what C and n are?
