Do the crossing out method. so if it is 2.50 per pound for peaches, try A, 11 pounds. 2.50 times 11 is 27.5, and now we have the rest, 154 pounds as apples so we multiply it by 1.75 which is 269.5, we add them up and we dont get 337.50, so we try out b, 18 times 2.5 is 45 so we still have 147 pounds left for apples, multiply it by 1.75 which is 257.25 and if we add up 45 and 257.25 we dont get 337.5 so now we try c which is 65, multiply it by 2.5 its 162.5 and we have 100 pounds of apples left. we do the same and we get 175, 175 plus 162.5 is 337.5 so C/3 is the correct answer
Step-by-step explanation:
= -2(x - 5) + 4(9 + x)
= -2x + 10 + 36 + 4x
= (-2 + 4)x + 10 + 36
= 2x + 46
Answer:
Even investing the $ 3,000 in the account at 8%, the result would be an annual interest of $ 240, with which there is an error in the wording of the question.
Step-by-step explanation:
Given that you invested $ 3000 between two accounts paying 4% and 8% annual interest respectively, to determine how much was invested at each rate if the total interest eamed for the year was $ 520, the following calculation must be performed:
3000 x 0.04 + 0 x 0.08 = 120
1500 x 0.04 + 1500 x 0.08 = 180
3000 x 0.08 + 0 x 0.04 = 240
Thus, as can be seen, even investing the $ 3,000 in the account at 8%, the result would be an annual interest of $ 240, with which there is an error in the wording of the question.
The questions ask you to caculate how many elements must a set of numbers of proper subsets of the set 1/2 of the total number of subsets per a subset,base on the question I bet the answer is 1 I hope this helps let me know if u passed and I will try to work it out again GREAT LUCK!!
