Answer:
4 dogs....hope it helps u
They have 69 cookies left.
Step-by-step explanation:
7 x 14 = 98
98 - 29 = 69
x1=-4/5, x2=18/5 and x3=7/5
you can do linear combination between the rows:
2nd row=R2-3R1 and 3th row=R3-2R1
3th row=(3R2-R3)/15
1st row=R1+3R3 and R2-11R3
4√36^-1 = 36^-1/4
36^3/4 • 36^-1/4
=36^2/4
or √36 = 6
