Question

PLEASE HELP!!

Answer 1

Step-by-step explanation:

what is the problem ? just take a deep breath, don't panic and think straight :

1) 12×k, which is usual written as 12k

2) u + 3

3) 1/5 × b = b/5

4) 10 - y

5) (a + 4) / 2

6) you did not say what is n summed with. so, I just designate this by "?".

(? + n) × 4

7) did you mean "take away one sixth from 4" ?

4 - 1/6

this can be simplified, as a whole number can be expressed by x/x (incl. 6/6). so, 4 = 4×6/6 = 24/6.

and so we have

24/6 - 1/6 = 23/6 = 3 5/6

8) d/2, often also written as d:2

9) 7 + v + w

10) the product of what with x ?

I designate this again by "?".

9 + ?x or

9 + ?×x or

9 + ?*x
