6+7X4
6+7X4
6+28
34
Tell whether the given value of the variable is a solution of the equation
16+Y=22, when Y=8
No
16+8=24
Describe the pattern. Then write the next three numbers.
100, 91, 82, 73,...
subtract 9 from the previous
64, 55,46

(1+6)(5-2)2
(1+6)(5-2)2
(7)(3)263
Tell whether the given value of the variable is a solution of the equation
9=z-12, when z=20
No
8=20-12
Describe the pattern. Then write the next three numbers
2, 3, 6, 11, 18,...
add 1, then add 3, then add 5, then add 7, and so on: 27, 38, 51

9/3X34
9/3X34
9/3X81
3x81
243
solve the equation using mental math
10X=120
10(12)=120
X=12
Consider the patterns 12, 21, 30, 39,.... Will the 15th number have a value that is less then 100? less then 200? Explain
you are adding 9 each time. by the 15th number you added 9 fourteen times, and 14X9=126. The 15th number is 12+126=138, which is greater than 100 and less then 200.
(13)(3)= 39
