1/2, 4/8, etc. Because they all equal to one half. <span />
l = 2w + 4
l * w = 48
We can substitute l with its value:
2w + 4 * w = 48
2w^2 + 4w - 48 = 0
2(w^2 + 2w - 24) = 0
2(w+6)(w-4) = 0
w = {4, -6}
The correct answer is B
325-45=280
8x35=280
So if she still has $27.12, then during her call, she used a total of $2.88.
$2.88 = 288 cents.
Therefore 288 divided by 6 = 48
Therefore the answer is 48 minutes.
Answer:
x = 30°
Step-by-step explanation:
So the total angle of a quadrilateral is 360°.
Your goal is to find x which associate numbers in each corner.
The equation to the quadrilateral is this:
a + b + c + d = 360°
a = ∠ABC = 4x
b = ∠BCD = 3x
c = ∠CDA = 2x
d = ∠DAC = 3x
∠ABC + ∠BCD +∠CDA + ∠DAB = 360°
4x + 3x + 2x + 3x = 360°
7x + 5x = 360°
12x = 360°
x = 360 ÷ 12
x = 30°
