Use properties of operations to determine whether the expressions are equivalent.
19) 7m + 10 + 9m and 16m + 10
20) 2b × 5 and 7b
21) 9 × (4r – 6) and 36r – 54
22) 12 + 5(2 + y) and 5y + 22
23) 15j + 11 – 6j and 9j + 11
24) 8(3x + 1) and 24x + 1

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
