Problem: -4-56x= 20. -56x=20+4. -56x/56=24/56. Answer: approx. .43
6x+7 = -56x = -12x = -2
53 squared equals 2,809.
It equals 53.
10x - 25 = 4x + 510x - 4x = 25 + 56x = 30x = 5
Problem: -4-56x= 20. -56x=20+4. -56x/56=24/56. Answer: approx. .43
6x+7 = -56x = -12x = -2
.56x=9-.44x x=9
7X^2 -56X + 112 = 0 divide through by 7 X^2 - 8X + 16 = 0 factor (X-4)(X-4) X = 4
8x - 7y = 7 (A)7x + 8y = 8 (B)7*(A): 56x - 49y = 498*(B): 56x + 64y = 648*(B)-7*(A): (64+49)*y = 64-49=> 113y = 15=> y = 15/113
53 squared equals 2,809.
1 x 53, 53 x 1
It equals 53.
10x - 25 = 4x + 510x - 4x = 25 + 56x = 30x = 5
-53 + 883 = 830
114-53=61
53 percent = 53/100 in fraction53%= 53%/100%= 53/100 in fraction
