i really need help
the + of a number and 10 k decreased by 4 = k-4
4x-9=k 4x=k+9 Divide by 4 to isolate the x x=(1/4)k+(9/4) x=1/4 k+ 9/4
.1
is multiplication , so you multiply like k(9)=36 then k would equal k=4 because you divide 9 by 36 and it equals =4
17/k
It is 2n/k
It is K/12.
Let the number be k. According to the question the equation is; (3.5 * k) / 4 = 70 (3.5 * k) =280 k = 280 / 3.5 =80 Therefore the number is 80.

40/x
1. (9 + k) - 17. (Since addition is commutative, this could also be written as k - 8.) 2. x - 23. 3. 15 + (60/w). 4. 37t - 9.85.
16 - 3k + 5 and k is 4, then 16 -12 + 5 = 9
