Arthur weighs 34 lb more than Lily. Their combined weight is 180 lbs less than four times Lily's weight. How much does Arthur we

mote1985 [20]

X = Lilys weight
x + 34 = Arthurs weight
4x - 180 = combined weight

x + x + 34 = 4x = 180
2x + 34 = 4x - 180
-2x -2x
_________________
34 = 2x -180
+180 + 180
_______________
214 = 2x
107 = x which is Lily's weight
141 = x + 34 which is Arthur's weight
The total weight is 248

which is the answer that you get when you do 4(107) = 180 or
428 -180 = 248

If B is the midpoint of AC, solve for x, and find the lengths of AB, BC, and AC.

makvit [3.9K]

Answer:

49, 49 , 98

Step-by-step explanation:

AC = AB + BC = 2AB

3x - 31 = 2(x+6)
3x - 31 = 2x + 12
3x - 2x = 12 +31
x = 43

AB= BC = x + 6 = 43 + 6 = 49

AC = 2AB = 2* 49 = 98

The quotient is $x^2-3x+1$

Step-by-step explanation:

The given polynomial division is $(x^3-4x^2+4x-1)\div (x-1)$

To perform the synthetic division we write out the coefficients and arrange them as shown.

1 -4 4 -1

1 -3 1 0

The quotient is $x^2-3x+1$

The descending powers of x means from highest degree to the least
