3(20 - b) = 36
60 - 3b = 36
-3b = 36 - 60
-3b = - 24
b = -24/-3
b = 8 <==
Answer:
(I'll leave cm out to save space and time in the answer)
the perimeter is 500, there are 5 sides. so on average a side will be 100.
that's already the important key idea.
it's indeed 100 for the third side, the second will be 10 less, the fourth 10 more (making the 2and and the 4th side 200 in sum, and therefore still 100 on average).
repeat this for the 1. and 5. side and we get:
80
90
100
110
120
Answer:
A
Step-by-step explanation:
The solution would be like this for this specific problem:
Given:
Total amount of the house
= £234,900
<span>Find:
Amount of deposit paid = ?</span>
So first, we divide the t<span>otal amount of the house by the percent of
deposit that Carol paid.
</span>= £234,900 / 10%
= £23,490
<span>Another way to solve this
is by converting the percent of the deposit into a decimal. We do this by
dividing the percentage amount by 100.
= 10% / 100% </span>
= 0.1
Next, we multiply the
decimal equivalent of the percentage to the total amount of the house.
= £234,900 * 0.1
= £23,490
So, the amount of deposit that was paid by Carol is £<span>23,490.</span>
