Which is the operation to do second based on the order of operations?
4+5×(7−3)

a. subtract 3 from 7
b. add 4 to the product of 5 and the difference of 7 and 3
c. multiply 5 by the difference of 7 and 3
d. multiply 7 by the sum of 4 and 5

Three consecutive even numbers have a sum between 84 and 96. a. write an inequality to find the three numbers. let n represent the smallest even number. b. solve the inequality. a. 84 ≤ n + (n + 2) + (n + 4) ≤ 96 b. 78 ≤ n ≤ 90 a. 84 < n + (n + 2) + (n + 4) < 96 b. 26 < n < 30 a. 84 < n + (n + 1) + (n + 2) < 96 b. 27 < n < 31 a. n + (n + 2) + (n + 4) < –84 or n + (n + 2) + (n + 4) > 96 b. n < –30 or n > 31
