The governing equation is z = k/x.
When x=3, z = 1 2/3, or z = 5/3. Find k: 5/3 = k/3. Then k = 5, and the
governing equation becomes z = 5/x.
Now if x=12,
z = 5/12 (answer)
Answer:
Step-by-step explanation:
You will need 34 square feet of carpet
2x+9=17
(solved is x=4)
Hope's its helps
1) x = 3
y = 42
2) x = 50
y = 70
1) 12x + 6 = 14x
6 = 2x
x = 3
14(3) = y
42 = y
2) 2x + 10 + x + 20 = 180
3x + 30 =180
3x= 150
x=50
2(50)+10=110
110-180
y=70
