What's m + 6/3 equals -8

Tom [10]

Answer:

see below

Step-by-step explanation:

m+6/3 = -8

Simplify the fraction

m+2 = -8

Subtract 2

m+2-2 = -8-2

m = -10

or

(m+6)/3 = -8

Multiply each side by 3

m+6 = -8*3

m+6 = -24

Subtract 6

m+6-6 = -24-6

m = -30

Which is the iterative rule for the sequence 3, 8, 13, 18, 23, . . . . ?

Nostrana [21]

Answer:

B) 5n – 2

Step-by-step explanation:

Given: 3, 8, 13, 18, 23, ....

$a_{1}=3=5(1)-2\\a_{2}=8=5(2)-2\\a_{3}=13=5(3)-2\\a_{4}=18=5(4)-2\\a_{5}=23=5(5)-2$

For the nth term, $a_{n}=5n-2$

Hence the iterative rule for the sequence 3, 8, 13, 18, 23, ... is 5n – 2.
