A wooden board 100 centimeters long is cut into two pieces. One piece is 16 centimeters longer than the other. What are the lengths of the two pieces?
Answers
x = the length of one piece
y = the length of the other piece
the total length is 100 cm this means
x + y = 100
one piece is 16 inches longer than the other
first we need to convert inches to cm:
1 in = 2.54 cm
16 in = 2.54*16 = 40.64
now we can write
x = y + 40.64
by solving the system of equations
x + y = 100
x = y + 40.64
we find
x = 70.32 cm
y = 29.68 cm
the lengths of the two pieces are 70.32 cm and 29.68 cm.

Answer:
y = -4x + 19
Step-by-step explanation:
The line parallel to y = -4x + 1 would have the same slope of -4. The coefficient of x will be -4. We can put this into the equation y = -4x + a where a is the y-intercept and a ≠ 1. Now solve for a.
y = -4x + a
plug in 4 for x and 3 for y
3 = -4(4) + a
simplify
3 = -16 + a
+16 both sides
19 = a
a = 19
y = -4x + 19

Given that;
A polygon is shown in figure.
Now, We get;
The polygon is made by two rectangles.
Hence, The area of the polygon is,
⇒ 17 x 5 + 11 x 5
⇒ 85 + 55
⇒ 140 units²
Thus, The area of the polygon is,
⇒ 140 units²
