For your fundraiser, you decide to hold a bake sale. In order to make bakery items, you had to purchase 12 pounds of sugar and 1
5 pounds of flour. Your total cost was $9.30. On a second trip to the grocery store, you purchased 4 pounds of sugar and 10 pounds of flour for a total cost of $4.60. Which of the following represent the system of equations for this problem.
The question seems to be pointing towards a multiple choice response but I will do my best. The first equation would be 15x+12y=9.30 and the second would be 10x+4y=4.60, x represents flour and y represents sugar.
Answer: True! Yes, sine and cosine are called co-functions, where the sign function of any acute angle equals it’s co-function of the angles complement.
