1. For each equation, decide if it is always true or never true. a. x - 13 = x + 1
b. x + 1 =x-1
c. 2(x + 3) = 5x + 6 - 3x
d. x-3 = 2x - 3-X
e. 3(x - 5) = 2(x - 5) +x

ratio is 2 : 9

the answer is three

13.5 : 3

answer: your answer is a

using pemdas, (order of operations) you'll see the answer is 24.

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the 14th row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
