Answer:
The correct answer is 54 rails.
Step-by-step explanation:
Max builds rail fences. For one style of fence, each section uses 3 vertical fence posts and 6 horizontal rails.
For every style of fence Max uses 3 vertical fence posts and 6 horizontal rails.
For every style of fence Max uses vertical fence posts and horizontal rails in the ratio of 1 : 2.
Max uses 27 posts . Therefore he needs to use 27 × 2 = 54 rails.
Therefore Max needs 54 rails for a fence that has 27 posts.
2/8
4/12
6/24
they can all be simplified to 1/4
The given are:
cost for each blog = $20
cost for each feature article = $60
blog = 10+2(number of articles sold)
total earnings = $700
where,
a = article
b = blog
to solve,
60(a)+20(10+2a)=700
60a+200+40a=700
200+100a=700
100a=700-200
100a=500
a=500/100
a=5
The total feature articles produced last week was 5.
to check,
a+b=700
60(5)+20[10+2(5)]=700
300+20(10+10)=700
300+200+200=700
700=700
Indeed, the number of articles produced last week was 5.
The given polynomial is
→ 6 ac - 15 a d- 8 b c + 2 b d
→ 3× 2×a×c - 3×5×a×d - 2×2×2× b×c + 2×b×d
→ 3 a ( 2 c -5 d) - 2 b(4 c -d)
