The sum of 3 times a number and 7 is 8 use the variable of w for the unknown number

⅓

Step-by-step explanation:

I solved it in the picture above

w =

Step-by-step explanation:

The equation representing the situation is

3w + 7 = 8 ( subtract 7 from both sides )

w = 1 ( divide both sides by 3 )

w =

The First answer is

VWXZ+VWXY+WYZ+VXY+VWZ+XYZ

The second possible answer is:

VWXZ+VWYZ+WYZ+VXY+VWZ+XYZ

Step-by-step explanation:

First we draw the k-maps for the function . There are two k-maps, one with V as zero while the other is V as 1. Then we combine the entries in power of 2. Remember that the function is given in maxterms form.Max-terms are those whose value is 0. So all the values other than max-values are either 1 or don't care. So we will keep these terms 0 and other as 1. The k-maps are attached in the files below. The essential prime implicants are those which are repeated in all the possible solutions.In this case Essential prime implicants are :

VWXZ+WYZ+VXY+VWZ+XYZ
