Letter b
Angles are supplementary ( the sum of both angles =180)
11x + 8 + 12x +11 = 180
23 x = 180 - 19
23x -= 161
X = 7
They will each cost $340 I think
False. This is because no matter what the number is, the properties of multiplication and division stay the same. So, if one odd and even number multiply/divide, then the answer will be negative. But, if two numbers of the same sign (both either negative or positive) are divided/multiplied, they will both be positive. Therefore, the result is not always the same sign as the starting integers
Hope this helped! :D
