Answer: the number of scented candles ... x
the number of unscented candles ... y
x + y = 28
$16 * x + $10 * y = $400 ... 16 * x + 10 * y = 400
Step-by-step explanation: This is the equation
16 * (28 - y) + 10 * y = 40016 * 28 - 16 * y + 10 * y = 400448 - 400 = 16 * y - 10 * y48 = 6 * y /6y = 48 / 6y = 8x = 28 - y = 28 - 8 = 20Result: The candle shop sold 20 scented candles and 8 unscented candles today.

Can you rewrite this equation on a piece of paper, please?
Answer:
= 8.9 units
Step-by-step explanation:
When a chord intersects with a tangent outside a circle then we use the relationship;
X ² = AO × BO, Where A and are the points of intersection of the chord an the circle, while O is the point of intersection between the chord and the tangent.
Therefore;
x² = 4 × 20 or 8 × 10
x² = 80
x = √80
= 8.944
≈ 8.9
Let, Width = x
Length = 2x - 5
So, perimeter = 110 = 2(l+w)
110 = 2(2x-5+x)
110 = 2(3x-5)
110 = 6x-10
6x = 110+10
x = 120/6
x = 20
So, 2x-5 = 2(20)-5 = 35
So, dimensions are 35 × 20
Hope this helps!
