Answer:
Step-by-step explanation:
The scale factor is 2/3
2/3=2*2/2*3=4/6
2/3=2*3/3*3=6/9
1) 2z= -6
divide both sides by 2
2z/2= -6/2
2 on the left cancels out
z= -3
2) y/-5= 20
multiply both sides by -5
(-5)(y/-5)= (-5)(20)
-5 on the left cancels out
y= -100
Hope this helps! :)

Answer:
110 yards of string
Step-by-step explanation:
Converting the feet of the string of 1 balloon to yard
1 foot = 1/3 yard
6 feet = x
x = 6 × 1/3 yard
x = 2 yard
Hence 1 balloon uses 2 yard of string
Since:
1 balloon = 2 yard of string
55 ballons = x
x = 55 × 2 yard of string
x = 110 yards of string
Hence, for 55 balloons he would need 110 yards of string.
