Let's break this down step by step using the order of operations (PEMDAS).
Therefore, 2 + 2 x 2 - 7 + 6 + 9 ÷ 4 + 7 - 5 x 10 = 42.5.
Let's break this down step by step using the order of operations (PEMDAS).
2 + 2 = 44 x 2 = 88 - 7 = 11 + 6 = 79 ÷ 4 = 2.252.25 + 7 = 9.259.25 - 5 = 4.254.25 x 10 = 42.5Therefore, 2 + 2 x 2 - 7 + 6 + 9 ÷ 4 + 7 - 5 x 10 = 42.5.
