The answer is 37. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
If: 2x+6x-4 = 52 Then: x = 7
Probability of drawing a 7 or 9 is the probability of draw a 7 plus the probability of draw a 9 which is 4/52 + 4/52 = 8/52 = 2/13 = 0.1538.
3+52+4 52+3=55+4 55+4=59
7q+13 = 52 7q = 52-13 7q = 39 q = 39/7

2 + 1 + 5 + 52 + 4 + 6 = 70

52-4*7*1 = -3 The discriminant is less than zero so the quadratic equation will have no solutions.
8x6 plus 4 equals 52.
4 + 48 = 52
