Answer:
23
Step-by-step explanation:
x = 6
given x varies inversely with y then
xy = k ← k is the constant of variation
to find k use the condition x = 4 when y = 9, hence
k = 4 × 9 = 36
x =
← inverse variation equation
when y = 6, then x =
= 6
1 foot = 12 inches
20 feet = 20 x 12 =240 in.
42 x 2= 84 in.
240 - 84 = 156 in. already cut
240 - 156 = 84 in
84/2 = 41 pieces are left to be cut
I think C would be for number 11
A is for 12.
x/2 < - 18
Answer:
i would be a reflection so the 2nd option
