Answer:
- A. 3(10÷2) +2·7
- A. 0.4
- B. -2.8
- C. n·6 - 12 = 60
Step-by-step explanation:
1. The given expression evaluates to ...
30÷2 + 2·7 = 15 + 14 = 29
The offered choices evaluate to ...
A: 3(10÷2) + 2·7 = 3·5 + 2·7 = 15 + 14 = 29 . . . . . this will make it true
B: 30÷(6+2)·7 = (30/8)·7 = 210/8 = 26 1/4 . . . . . . ≠ 29
C: 3(10)÷(2+2)·7 = 30/4·7 = 210/4 = 52 1/2 . . . . . ≠ 29
D: (5+2)·7 = 7·7 = 49 . . . . . . . . . . . . . . . . . . . . . . . ≠ 29
2. You can divide the equation by 10 to find the appropriate value of x.
4/10 = 10x/10 = x . . . . . 4/10 matches choice A
3. The expression simplifies to ...
7.5 -10.3 = -2.8 . . . . . . matches choice B
4. "The product of a number and 6" is n×6. Twelve less is n×6 - 12. When that "is 60", the equation can be written ...
n×6 - 12 = 60 . . . . . . . . matches selection C

One way to do it is to find an explicit formula for the
th term.
The pattern suggests that the
th term is given by
, and so the fifth term is
.
Another way to do it would be to plug
into the recursive formula to find
, then
, and so on.
