Answer:
0,4
Step-by-step explanation:
1. 2/5=0,4; 6/15=0,4; 8/20=0,4. It means, the constant of proportionality is 0,4.
2. if the constant value is 0,4, then x:1=0.4 ⇒ x=0,4
First distribute the 1/5 through the parentheses.
1/5 (3 + 2z) - 4z = -3
3/5 + 2/5z - 4z = -3
subtract 3/5 from each side
2/5z - 4z = -3 - 3/5
combine like terms
-3 3/5z = - 3 3/5
z = 1
