3/4 + 2 1/4 + 3/4 + 9/16 ~ Begin by making all mixed numbers improper fractions 2 1/4 --> (2*4+1)/4 --> 9/4 3/4 + 9/4 + 3/4 + 9/16 ~ Next, make all denominators the same by finding a common denominator (in this case, 16) 3/4 * 4/4 --> 12/16 9/4 * 4/4 --> 36/16 3/4 * 4/4 --> 12/16 12/16 + 36/16 + 12/16 + 9/16 ~ Now add all of the numerators (12+36+12+9)/16 (69)/16 69/16 Either leave the answer as 69/16 or use a calculator to find: 4.3125

4x+9=25 4x+9=25-9 4x/4=1 16/4=4 4x+9=26 4(4)+9=25 16+9=25 The answer is 4

4 + 4 + 1 = 9

9 + 4 * 3 / 3 + 4 - 1 Use BIDMAS or PEDMAS (or equivalent) Division first, gives: 9 + 4 * 1 + 4 - 1 Then multiplication: 9 + 4 + 4 - 1 Then addition(s): 17 - 1 Finally subtraction: 16

16 + 9 - 4 = 21

9 - 20 / 4 + 16 = 9 - 5 + 16 = 20

1 + 4 + 4 = 9

Factors of 4: 1, 2, 4 Factors of 9: 1, 3, 9 Factors of 16: 1, 2, 4, 8, 16 GCF (4, 9, 16) = 1

8 + 1 = 9 5 + 4 = 9 9 + 9 = 18 ( 8 + 1 + 5 + 4 = 18) The answer is 18.

16 + 2 + 9 + 4 + 7 + 8 is = 18 + 9 + 4 + 7 + 8 = 27 + 4 + 7 + 8 = 31 + 7 + 8 = 38 + 8 = 46

9/16 + 2/8 9/16=9/16 2/8=4/16 9+4=13 so......13/16 is the answer!

16 + 9 + 4 + 1

sqrt(16) + 9 =Â± 4 + 9 = -4 +9 or +4 +9 that is 5 or 13sqrt(16+9) = sqrt(25) =Â±5

16/12 or 4/33/4 * 3/3 = 9/121/2 * 6/6 = 6/12................1/12===========...............16/12 or 4/3

-2x^4+16 +2x^4+9-3x^5=-3x^5+25. There is no "answer" because there is no equation.
