If this is: 8x - y = 20 -5x = y - 8 8x - y = 20 -5x - y = -8 multiply by -1in order to eliminate y; 8x - y = 20 5x + y = 8 add both equations; 13x = 28 x = 28/13 substitute the value of x into the one of the equations in order to find y. For example, substitute it into the first one; 8(28/13) - y = 20 224/13 - y = 20 multiply both sides with 13; 224 - 13y = 260 224 - 224 - 13y = 260 - 224 -13y = 36 multiply both sides by -1; 13 y = -36 divide both sides by 13; y = -36/13 So the solution set is (28/13, -36/13) Check: 8(28/13) -(-36/13)= 224/13 + 36/13 = 260/13 = 20 -5(28/13) = -36/13 - 8 ? -140/13 = -36/13 -8 ? -140/13 = -36/13 - 8(13/13) ? -140/13 = -36/13 - 104/13 ? -140/13 = -140/13
The square numbers between 10 and 40 are 16,25 and 36.
Not evenly because it will have remainder of 13
13/36 cannot be simplified.
13 is 36.11% of 36.
yes because 13 x 2 is 36
13/36
13 multiplied by 36 is 468.
36 q -13 = 23
36 multiplied by 13 is 468.
36*13/100 = 4.68
36
13 + 23 = 36 5 + 7 + 11 + 13 = 36 2 + 3 + 7 + 11 + 13 = 36 5 + 31 = 36
The answer is 36/13 which is approx 2.77
4 goes into 36 evenly, but 13 does not.
