8z − 4 = 7z
move 8z to the other side
sign changes from +8z to -8z
8z-8z-4=7z-8z
-4= 7z-8z
-4= -z
mutiply both sides by -1 to get +z
(-4)(-1)= (-z)(-1)
Answer:
z= 4

Answer:
<u>Length of 1 piece= Length of total divided by 8</u>
Step-by-step explanation:
Length of total= 5.24 feet long
Width of total= 1.34 feet wide
Width is divided by 1 line so, there are 2 parts.
Width= 1.34 divided by 2
Width= 0.67 feet wide
Length is divided by 7 lines, so there are 8 parts.
Length= 5.24 divided by 8
Length=0.655 feet long
They are asking for formula to find the length of each piece
<u>Length of 1 piece= Length of total divided by 8</u>
<u></u>
Hope that helps!
