Answer:
Weight of nuts = 6 pounds.
Weight of cereal squares = 6 pounds.
Step-by-step explanation:
Let the weight of nuts used in the trial mix to be x pounds and the weight of cereal squares used in the trial mix to be y pounds. Total weight of the mixture is 12 pounds. Therefore: x + y = 12. This implies y = 12 - x (Equation 1).
Cost of nuts per pound = $8 and cost of cereal squares per pound = $3. Cost of the mixture per pound = $5.5. Total mixture = 12 pounds. Since x pounds of nuts and y pounds of cereal squares are used, therefore: 8x + 3y = 5.5 * 12.
8x + 3y = 66. (Equation 2).
Put equation 1 in equation 2.
8x + 3(12 - x) = 66.
8x + 36 - 3x = 66.
5x = 30.
x = 6.
Put x = 6 in equation 1.
y = 12 - 6.
y = 6.
Therefore, the weight of nuts used in the trial mix will be 6 pounds and the weight of cereal squares used in the trial mix will be 6 pounds!!!
Step-by-step explanation:
(4/3)–1 = 3/4 and (1/4)–1 = 4/1
now we have,
(3/4 - 4)–1 = (-13/4)–1
= -4/13
If you mean by spectacles, it would cost Malcom about $3.60 for a pair.
