7x=210
x=30
Matrix dimension 4x4. We put 1 if role is in relation with the collon (role is first number of (a,b), number a, and collone is number b. We have them 4). So, the matrix representation is:
0 0 1 1
0 1 0 0
0 1 0 0
0 0 0 0
Answer:
658.91$
Step-by-step explanation:
Find the total cost

Total cost is 397$+233.69$+28.22=658.91$
Answer-44
You can turn both of the denominators ( bottom numbers on the fractions ) into 120 ( the whole number ) and the top numbers can be multiplied by how many times the denominators went into 120. Then add the top numbers which equals 76 and then 120-76=44. Hope that kinda helps !!
