x+y=7\nxy=25\n1/x+1/y=?\nif you add by making both denominators equal (gcf is xy) you get\n(y+x)/(xy)=7/25

the answer is pie over 2x plus 7

Lets call the numbers 2a-27, 2a-25, 2a-23, ..., 2a+23, 2a+25, 2a+27. Thats 28 numbers, and since all the constant terms cancel out, their sum is 28*2a = 56a = 7a*2^3.\nSince we already have a factor of 2^3 in there, all we need for the entire thing to be a cube is a = 7*7*cube.\nThe smallest value of a gives the smallest p and the smallest q, so a = 7*7 = 49.\nThat gives p = 71, q = 125, average = 98, ie B.

Sn = n(n+1)/2\nS = 25(25+1)/2\nS = 25*13 = 325

(10+15+23+37+45) / 5 = 26

Well the correct is both 15 and 95.\nTaking 15 :\n(1)^2 + (5)^2 = 26 which is 11 more to 15\n2(1)(5) = 10 which is  5 less than 15\n\nTaking 95 : \n(9)^2 + (5)^2 = 106 which is 11 more to 95\n2(9)(5) = 90 which is 5 less than 95

let the numbers be x and y\nSo x + y = 7\nxy = 25\n\nNow 1/x + 1/y \n= x/xy + y/xy\n= (x + y)/xy\n= 7/25\n\nx + y = 7 So y = 7 - x\nxy = 25\n\nSo x(7 - x) = 25\n\n7x - x² = 25\n x² - 7x + 25 = 0\nx = [-b ± √(b² - 4ac)]/(2a)\n= [7 ± √(7² - 4.1.25)]/(2)\n= [7 ± √(- 51)]/(2)\n\nSo x = [7 - √(- 51)]/(2) and y = [7 + √(- 51)]/(2) \nThus 1/x = 1/[7 - √(- 51)]/(2)\n= 2/[7 - √(- 51)] * [7 + √(- 51)]/[7 + √(- 51)]\n= 2[7 + √(- 51)]/(49 - -51)\n= [7 + √(- 51)]/50\n\n1/y = [7 - √(- 51)]/50\nSo 1/x + 1/y = [7 + √(- 51)]/50 + [7 - √(- 51)]/50\n= 14/50\n= 7/25 (as above but with much more effort!!!!!!!!)

Product means the number resulting from the multiplying of two or more numbers together, therefor the answer is 22 x 431 =9482

$25 x .20 = $5\n\n$30 x .25 = $7.50\n\nThat is about the shortest way to them - just change the % to a decimal and multiply, remembering to put the decimal point in the right place.  I hope this helps.

Problem 16:\n6 x 1/n(reciprocal of n) = 2 x 1/2(reciprocal of 2)\n\nFirst, a number times it's reciprocal is always 1.\n\n6 x 1/n = 1\n\nSubtract 6.\n\n1/n = -5\n\nMultiply n.\n\n1 = -5n\n\nDivide by -5.\n\nn = 1/-5\n\nTo spgrabia: Think about order of operations. (1/x) must be done first.

This is how it works...\n#70 is 7+0=7 and 70-7=63\n#71 is 7+1=8 and 71-8=63\n#72 is 7+2=9 and 72-9=63

3(6) + 7 = 24\n18 + 7 = 24\n\n25 = 24\n\nNo.

This is more of a word problem or a riddle than a math problem.\n\nThe answer is 7 (SEVEN).  Remove its first letter and it becomes EVEN!
