3x + 16 = 22 3x = 6 x = 6/3 x = 2
2.75 x 8 = 22 or 8 x 2 = 16 3/4 x 8 = 24/4 = 6 16 + 6 = 22
x2 + 8x - 6 = 0 x2 + 8x + 16 = 22 (x + 4)2 = 22 x + 4 = ± √22 x = -4 ± √22
If you mean (1) y + 3x = 22 and (2) y + 2x = 16, then (1) y = 22 - 3x (sub this into (2)) (2) (22 - 3x) + 2x = 16 -x = -6 x = 6 y = 22 - 3x = 22 -3(6) = 4 solution: (6,4)
22% of 16= 22% * 16= 0.22 * 16= 3.52
3x + 16 = 22 3x = 6 x = 6/3 x = 2
6 + 42 = x 6 + 16 = x 22 = x
2.75 x 8 = 22 or 8 x 2 = 16 3/4 x 8 = 24/4 = 6 16 + 6 = 22
(x+6)+x=38 2x+6=38 2x=38-6 x=32/2 x=16 Therefore the one number is 16, and the other number is (16+6) which is 22. 16+22=38
x2 + 8x - 6 = 0 x2 + 8x + 16 = 22 (x + 4)2 = 22 x + 4 = ± √22 x = -4 ± √22
6, x, 16 mean (average) = (6 + x + 16)/3 = 11 (22 + x)/3 = 11 22 + x = 33 x = 11 The age of the second child is 11 years old.
If you mean (1) y + 3x = 22 and (2) y + 2x = 16, then (1) y = 22 - 3x (sub this into (2)) (2) (22 - 3x) + 2x = 16 -x = -6 x = 6 y = 22 - 3x = 22 -3(6) = 4 solution: (6,4)
The LCM of 6, 16 and 44 is 528. 6 x 88 = 528 16 x 33 = 528 44 x 12 = 528 prime factorization: 6 = 2 x 3 16 = 2 x 2 x 2 x 2 = 24 44 = 2 x 2 x 11 = 22 x 11 The LCM o 6, 16, and 44 is 24 x 3 x 11 = 528.
22% of 16= 22% * 16= 0.22 * 16= 3.52
6 x 3 7/16 x 3 11/16
-16 = 6x Swap: 6x = -16 Divide both sides by 6: x = -16/6 = -8/3 or -22/3 or -2.66...
22 x 16 = 352
