12
Step-by-step explanation:
To determine the number of discs, divide the area of the metal sheet by the area of the discs
The metal sheets are in the shape of a rectangle, thus the area of a rectangle would be used to determine the area of the sheet
Area of a rectangle = length x breadth
56 x 33 = 1848 cm^2
The disc is in the shape of a circle.
area of a circle = πr²
π = 3.14
r = radius
3.14 x 7² = 153.86 cm²
Number of discs = 1848 /153.86 = 12
<span>y= 2x-4
y= -x+5
so
</span><span>2x-4 = -x+5
2x +x = 5 +4
3x = 9
x =3
y = 2x-4
y =2(3) - 4
y = 6-4
y = 2
