What is the answer to 5x plus 6 equals 1divided by 4 times 13x-11?
5x + 6 = 1 / 4(13x-11)(5x+6)(4)(13x-11)= 14(65x2-55x+78x-66)=1260x2 +92x-264-1=0260x2+92x-263=0Graph y = 260x2 +92x -263 and find its zero or use the quadratic formula
Find the measure of an angle that is 54 degree less than two times its supplement?
let x be the anglelet y be the supplementx = 2y - 54x + y = 1802y - 54 + y = 1803y = 234y = 78x = 180 - 78x = 102The measure of the angle is 102

What is the product of 78 and 6?
product = times! (x)So 78 x 6 = ?78x 6------------------(6x8)= 048(6x70)=420(don't forget to write the 0 first to indicate it's 7x10 (70)not just 7!)--------------------= 468---------------------OR.....do it in your head!!think of it just as 6 x 70(the 70 out of the 78...rounding down to nearest ten makes an easy times sum!)..... (6x7 = 42 ! ...SO ... 6x70=420!)PLUS 6 x 8 ...= 48so......... 420 plus 48... = 468 !!!!!EASY!!OR JUST USE A CALCULATOR?
The three numbers of the combination for a padlock are consecutive integers and their sum is 81?
Three consecutive integers: x, (x+1), (x+2)Sum: x + (x+1) + (x+2) = 81x + x + 1 + x + 2 = 813x + 3 = 813x = 78x = 26The numbers are 26, 27, 28.=================Check:26 + 27 + 28 = 81 yay!
Find two numbers such that the sum of seven times the smaller and twice the larger is 155 and the difference between eight times the smaller and the larger is 3?
Let the smallest number be x, and the larger number be y. So we have:7x + 2y = 1558x - y = 37x + 2y) = 1552(8x - y) = 2(3)7x + 2y = 15516x - 2y = 6(7x + 2y) + (16x - 2y) = 155 + 67x + 16x + 2y - 2y = 155 + 623x = 16123x/23 = 161/23x = 78x - y = 38(7) - y = 356 - y = 356 - 3 - y + y = 3 - 3 + y53 = yThus, the number are 7 and 53.Check:
