So if I'm reading it correctly: x * (7%) = y + x = 55. So you have two different expressions, both equal to 55. x * (7%) = 55. Change 7% to 0.07, then divide both sides by 0.07 --> x = 5500/7 y + x = 55, with x = 5500/7 from above. y + 5500/7 = 55 --> y = 55 - 5500/7 = -5115/7 So x = 5500/7, or approximately 785.71 ; y = -5115/7, or approximately -730.71
8x+7=55 8x=55-7 8x=48 x=48/8 x=6
x(0.07) = 55 x = 55 / (0.07) x = 785.7142857...
To solve this system [x*7% = y], [x+y = 55], first solve for y in the second equation: y = 55-x. Then, substitute y in the first equation for 55-x: x*7%=55-x. Since x*7% is 1.07x, we can say that: 1.07x = 55-x. Then, add x to both sides to get: 2.07x = 55. Divide by 2.07, and x = 25.57. Finally substitute 25.57 for x in the second equation to get: 25.57+y = 55 , and y = 24.43. Therefore, x = 25.57, and y = 24.43
8x+7=55 8x=55-7 [subtract 7 from both sides] 8x=48 x=48/8 [divide both sides by 8] x=6
to solve this answer plz go to the bottom of this : 55 x 1 = 55 2 x 55 = 110 3 x 55 = 165 4 x 55 = 220 5 x 55 = 275 6 x 55 = 330 7 x 55 = 385 8 x 55 = 440 9 x 55 = 495 10 x 55 = 550 11 x 55 = 605 12 x 55 = 660 THANKS !
1 x 55 = 55 1 x 60 = 60 2 x 60 = 120 3 x 60 = 180 2 x 55 = 110 3 x 55 = 165 4 x 55 = 220 5 x 55 = 275 6 x 55 = 330 7 x 55 = 385 8 x 55 = 440 9 x 55 = 495 10 x 55 = 550
5 x 11 = 55 2 x 5 x 7 = 70 2 x 5 x 7 x 11 = 770, the LCM
55 = 5x + x + 7Combine the 'x's on the right side:55 = 6x + 7Subtract 7 from each side of the equation:48 = 6xDivide each side by 6 :8 = x
x2 - 2x + 55 = 90x2 - 2x - 35 = 0(x+5)(x-7) = 0x = -5, 7
4 with 7 remaining 55 - 7 = 48 = 12 x 4
55 x 7 = 385 miles
