Answer:
X = (J+M)/K
Step-by-step explanation:
Undo what has been done to the variable, in reverse order. The variable has been multiplied by K and M subtracted from the result. So, we first add M (to undo the subtraction), then we divide by K (to undo the multiplication).
KX = J +M . . . . . . M added to the given equation
X = (J + M)/K . . . . the result of that is then divided by K
___
Since these are all capital letters, we might assume they represent vectors and/or matrices. If so, the "divide by K" step needs to be "multiply on the left by K^-1, the matrix inverse of K."
Then your solution looks like
X = K⁻¹·(J + M)
Answer:
36
Step-by-step explanation:
Answer:
7a+1
Step-by-step explanation:
Okay so what you are supposed to do is simplify that for your answer. How you do this is by circling the things in common. So for example "4a" and "3a" are in common, so 4a plus 3a is 7a. Now look at the next things in common which would be "-5" and "6" add those together and you get 1.
To find the answer multiply $175 by 0.2. This will give you $35. Now, you have to subtract $175 by $35. Therefore, the sale price will be $140.
No i dont think so but i could be wrong i will double check to be sure though
