Answer:

B = (2, -5)

Step-by-step explanation:

The problem requirements mean ...

B - A = (2/3)(C - A)

B = A + (2/3)C - A

B = (1/3)A + (2/3)C = (A +2C)/3

B = ((-6, 1) +2(6, -8))/3 = (-6+12, 1-16)/3 = (6, -15)/3

B = (2, -5)

irina [24]

Answer:

The total length of fabric sue buys is 8.5 yards and total cost of the fabric is $42.5 .

Step-by-step explanation:

As given

Sue buys 5 pieces of fabric.

$Each\ piece\ is\ 1 \frac{7}{10}\ yards\ long.$

i.e

$Each\ piece\ is\ \frac{17}{10}\ yards\ long.$

$Total\ length\ of\ fabric\ sue\ buys = \frac{5\times 17}{10}\ yards$

$Total\ length\ of\ fabric\ sue\ buys = \frac{85}{10}\ yards$

In the decimal form

Total length of fabric sue buys = 8.5 yards

As given

One yard of the fabric costs $5

$Total\ cost\ of\ fabric\ sue\ buys = 8.5\times 5$

= $ 42.5

Therefore the total length of fabric sue buys is 8.5 yards and total cost of the fabric is $42.5 .
