Answer:
200 pencils and 120 pens
Step-by-step explanation:
Let the number of pencils be x while pens be y.
Considering the cost of whole purchase then, we get the equation
0.5x+y=220
Considering the number of items bought, then the equation is
x-y=80
Adding the two equations then we have
1.5x=300
x=300/1.5=200
Consideeing that x-y=80 and x is 200 then
200-y=80
y=200-80=120
Therefore, the pencils were 200 and pens 120 pieces
If a 4 sided figure has 360°...for each side we add, we add 180°.
you have a 7 sided figure (360° + 3(180°) = 900°)
adding up your angles (781) and subtract it from 900 =
x = 119°
What multiplies to 25 and adds to -10
-5 and -5
(x-5)(x-5)
(x-5)²
