Answer:
B
Step-by-step explanation:
To find the sales tax on a purchase of $49, what we simply do is to find 7% of $49. This means that we do the percentage calculation. To do this , we simply place 7 all over 100 and multiply by the purchase amount
This can be written as 7/100 * 49 and this is same as 0.07 * $49
B is the correct answer
Well, we would solve it as cancelling out -1/2 by multiplying it by its reciprocal (-2/1) to get x by itself, and now we'll do the same on the other side, where 6/1 times -2/1 = -12/1, which is the same as -12.
So x = -12 :3
