Answer:
x= 3
y= 3
Step-by-step explanation:
Step: Solve−x+y=0 for y:
−x+y=0
−x+y+x=0+x (Add x to both sides)
y=x
Step: Substitute x for y in 4x−3y=3:
4x−3y=3
4x−3x=3
x=3 (Simplify both sides of the equation)
Step: Substitute 3 for x in y=x:
y=x
y=3
Answer:
703.7cm²
Step-by-step explanation:
Since we must not count the top and bottom 2cm,
- The height of the label is (20-2-2) = 20 - 4 = 16cm
- Finding the curved surface area of a cylinder: 2πrh
where r = radius and h = height.
- Since the diameter is 14cm, the radius is 14/2 = 7cm
- Substituting 'r=7' & 'h=16' into the curved surface area of a cylinder formula:
2π(7)(16)
= (14)(16)π
= 224π
= 703.716754404cm²
≈ 703.7cm²
