Answer:
Median
Step-by-step explanation:
It is symmetric so you have a much easier way to find the middle numbers.
All you need to do is to subtract the x-coord. of G from the x-coord of H:
-2 - 3 = -5. Distance is not a signed quantity, so we'll give the final distance between points G and H as 5.
Answer:
a = + or - sqrt(7)/6, which are irrational ( Answer Choice (b) ) for either case.
Step-by-step explanation:
a^2 = 7/36 implies that
a^2 - 7/36 = 0, by subtracting 7/36 from both sides of the equation, which implies that
(a - sqrt(7)/6)(a + sqrt(7)/6) = 0, by factoring, which implies that
a - sqrt(7)/6 = 0 or a + sqrt(7)/6 = 0, by the zero product property of the real number system, which implies that
a = sqrt(7)/6 or a = - sqrt(7)/6, which are both irrational, since sqrt(7) is irrational and an irrational number divided by an integer (other than 0) is irrational.
Answer:
2n+5 =3
n=-1
The number is -1
Step-by-step explanation:
Let n be the number
Twice the number
2n
Plus 5
2n+5
is means equals
2n+5 =3
Now we want to solve
Subtract 5 from each side
2n+5-5 = 3-5
2n = -2
Divide each side by 2
2n/2 = -2/2
n = -1
Since we neither want most expensive nor least expensive, we need to go with pillow which is costing $18.49.
So total 4 pillows cost = 4*18.49
= $73.96
