Answer: 1/3 pound pecans and 2/3 pound walnuts.

Explanation: 

x ==> weight of walnuts
y ==> weight of pecans

║ x + y = 1 
║ 8x +2y = 6

║ x = 1 - y
║ 8x + 2y = 6

8(1 - y) + 2y = 6

8 - 8y + 2y  = 6

y = 1/3

x = 1 - 1/3 = 2/3

#5 The MAC is 4 centimeters. Find the circumference of B. Round your answer to the hundredths.
bixtya [17]

Answer:

C ≈ 11.71 cm

Step-by-step explanation:

using the ratio arc  AC : circumference C = angle at centre of sector : 360°

\frac{AC}{C} = \frac{123}{360} , that is

\frac{4}{C} = \frac{123}{360} ( cross- multiply )

123 × C = 4 × 360 = 1440 ( divide both sides by 123 )

C = \frac{1440}{123} ≈ 11.71 cm ( to the nearest hundredth )

4 1/4 divided by 1 1/2
MakcuM [25]
Hello, Briana so when dividing fractions, its best to put them in decimal form so that you can divide or multiply better. Now having this in mind, 4.25 divided by 1.5 becomes the new equation and using simple math on a calculator, we can conclude that the answer to this question is 1.7 in decimal form or 1 and 7 over 10 in fraction form. Hope this helped, if you have any questions, please ask!
