James is building a deck for a client and has several pieces of wood he wants to use. The sizes of the pieces of wood are 1.5m,

TiliK225 [7]

Answer:

$Total = 9.65m$

Step-by-step explanation:

Given

$Pieces: 1.5m, 2500mm, 850mm, 4.8m$

Required

The total length in metres (this completes the question)

The total length is:

$Total = 1.5m + 2500mm + 850mm + 4.8m$

Convert mm to m

$Total = 1.5m + 2500*0.001m + 850*0.001m + 4.8m$

$Total = 1.5m + 2.5m + 0.85m + 4.8m$

$Total = 9.65m$

<em>The total length of the wood is 9.65 metres</em>

Answer:

10x-2y

Step-by-step explanation:

distribute for both of them then multiply both answers by 2 and add them

2(x+y)= (2x+2y) x2= 4x+4y

3(x-y)= (3x-3y) x2= 6x-6y

4x+4y+6x-6x

10x-2y

Plz help! It’s not hard I just don’t properly understand

jonny [76]

Answer:

$a_{13}=2(13)+13=39$

39 is the 13th term

Step-by-step explanation:

Okay so essentially the $a_n$ is just a substitute for x.

See how in the equation they put n into the x spot:

$y=mx+b\\a_n=mn+b\\a_n=2n+13$

They changed the variable names:

$y=a_n\\m=2\\n=x\\b=13$

Now we know what the n actually means, plus when they ask about the terms youre trying to find it's based off of that n:

When they say, 13 term, they mean $a_{13}$ which would be the 13th answer in the series. So the first term would be based off of $a_1$

$a_1=2(1)+13\\a_1=15$

So whatever number is in the n position by a is what you'll be plugging into the x spot.

$y=mx+b\\a_n=2n+13\\a_1=2(1)+13=15\\a_2=2(2)+13=17\\a_3=2(3)+13=19\\a_4=2(4)+13=21\\a_5=2(5) +13=23\\a_6=2(6)+13=25\\a_7=2(7)+13=27\\a_8=2(8) +13=29\\a_9=2(9)+13=31\\a_{10}=2(10)+13=33\\a_{11}=2(11)+13=35\\a_{12}=2(12)+13=37\\a_{13}=2(13)+13=39$

These are all the answers leading up to the 13th term they asked for, and you can continue thus same equation with whatever number you can put into the n space.
