415+86+12(2+5) first start by multiplying 12 and 2 and you will get 24 then multiply 12 and 5 and you get 60 so 415+86+24+60=585
Solution:
We have to prove that ,
△ABC ~ △Z Y X Using SAS.
It is given that , ∠X ≅ ∠C .
You must keep in mind when two triangles are similar by S A S
1. The included side between the angle should be Proportional.

2. We have to prove that ,
△ABC ~ △Z Y X Using SAS.
It is given that , ∠B ≅ ∠Y .
The included side between the given angle should be Proportional.

3. We have to prove that ,
△ABC ~ △Z Y X Using SSS.
The three sides of two triangles must be Proportional.

Answer:
The average number of customers per day during the sale was 150.
Step-by-step explanation:
This question can be solved using a rule of three.
Before the sale, the average number of customers per day was 120, which is 100% = 1.
Now, there are x customers, and since it is an increase of 25%, it is 100+25 = 125% = 1.25. So
120 - 1
x - 1.25
x = 1.25*120 = 150
The average number of customers per day during the sale was 150.
I'm no expert, but considering it went down its probably a decease. (duh). I think its 77%, but I'm not very good with percentages
<span>This problem can be easily
solved using algebra.<span>
Since
James wants to know how many months he will have $810, we need to simplify it in an equation.</span></span>
Let x = number of months
$360 + $90x = $810
We transfer $360 to the other
side and reverse operation
$90x = $810 - $360
Now it is simplified to this
$90x = $450
n order to find the value of
x, we divide 90 to both sides
$90x/90 = $450/90
…and arrive at the answer.
X = 5
<span>Therefore, it will take 5
months for James to save in order to get $810 in his bank account.</span>
