Correct answer: 18
[(15 - 9) ÷ 2] x (10 - 4) = 18
Correct answer: 3, 6, 24, 36
The rule is x3, so plugging in each input number results in the following:
1 x 3 = 3, 2 x 3 = 6, 8 x 3 = 24, 12 x 3 = 36
Correct answer: Starting at the origin, move 4 units to the right.
The first step to take in locating the point is to start at the origin, move 4 units to the right.
Correct answer: 4
[(12 + 4) x 3] ÷ (6 + 6) = 4
Correct answer: 4, 5, 13, 22
The rule is +4, ÷2, so plugging in each input number results in the following:
(4 + 4) ÷ 2 = 4, (6 + 4) ÷ 2 = 5, (22 + 4) ÷ 2 = 13, (40 + 4) ÷ 2 = 22
Correct answer: 37.88 inches
40.5 - 2.62 = 37.88
Correct answer: (5 , 9), (9 , 17), (14 , 27), (25 , 49)
The rule is x2, -1, so plugging in each input number results in the following:
5 x 2 - 1 = 9, 9 x 2 - 1 = 17, 14 x 2 - 1 = 27, 25 x 2 - 1 = 49.
To create coordinate pairs, write the input number followed by the output number, separated by a comma, in parentheses.
