Answer:
0.4 as a fraction would be 2/5
(35-21) = 14 so your answer would be 14
(7/6 x 30= 35 and 7/6 x 18= 22

Answer:<span>f=<span><span>−4/</span><span>3
-Hope this helped
if you legit just meant f(3)
that would be

Answer:
27 vertical posts and 36 horizontal rails
Step-by-step explanation:
If Max builds 1style of fence with each section having 3vertical posts and 6horizontal rails, to calculate the number of posts and rails that he need for a fence that will be 9 sections long, we will use the following equality;
For Posts:
1section = 3 vertical posts
9 sections = x
Cross multiply
x × 1 = 9× 3
x = 27
Hence Max will need 27vertical posts for a fence that is 9sections long
For the rail:
1 section = 6 horizontal rails
6 sections = y
Cross multiply
y× 1 = 6 × 6
y = 36
Hence Max will need 36 horizontal rails for a fence that is 9sections long.
In total Max will need 27 vertical posts and 36 horizontal rails for a fence that is 9sections long
