45 = 2x - 5

Add five to each side

50 = 2x

divide both sides by 2

25 = x

the value of x is 5

Answer: the value of x is 70

Steps:

the angles 45 and (2x-5) are supplementary, so they add up to 180 degrees. We use that property to solve for x:

2x-5 + 45 = 180

2x = 140

x=70

3(x+2)=5x in backtracking method
zvonat [6]

I don't know what the backtracking method is, sorry.


3(x + 2) = 5x


3x + 6 = 5x


6 = 5x - 3x = 2x


x = 6/2 = 3

Nancy decides to buy 30 panels for her allotment and her garden. The panels need to be treated with wood preservative. Each pane
Vesnalui [34]
<h2>Hello!</h2>

The answer is:

She will need 9 tins to cover all the panels.

<h2>Why?</h2>

To find how many tins will she need to cover the 30 panels for her allotment and her garden, we need to calculate the total area of the panels and then, calculate how many tins will she need knowing that each liter of tin, covers 12 square meters.

We are given the dimensions of the panels:

Long=1.8m\\Hight=2m

Now, calculating the area of one (1) panel, we have:

Area=long*height=1.8m*2m=3.6m^{2}

So , the total area of all 30 panels is:

TotalArea=30*3.6m^{2}=108m^{2}

Then, calculating how many tins will she need to paint all the panels, we have:

NeededTins=\frac{TotalArea}{AreaToCoverWithOneTin}\\\\NeededTins=\frac{108m^{2}}{12m^{2} }=9

Hence, we have that she will need 9 tins to cover all the panels.

Have a nice day!
