-32 + 17x = -11x
+ 11x +11x
-32 + 28x = 0
+32 +32
28x = 32
/28 /28
x = 32/28 or 8/7
Step-by-step explanation:
Go 2.5 units to the right from the origin (0,0) for your x coordinate
Go 2.5 units down from the origin (0,0) for your y coordinate
Where the lines meet is your point.
So we are assuming that the three shirts have equal price. Let the price of one shirt be a.
In store A:
the cost is (a+a+a) -(25/100)a=3a-0.25a=2.75a
In store B:
the cost is : a+a+50/100 a =a+a+0.5a=2.5a
In store C:
the cost is
[a-(10/100)a]+[a-(10/100)a]+[a-(10/100)a]=[a-0.1a]+[a-0.1a]+[a-0.1a]
=0.9a+0.9a+0.9a= 2.7a
thus the cost of buying the shirts from stores A, B and C is:
2.75a, 2.5 a and 2.7 a respectively.
the best deal, is buying from store B, where the cost is the lowest: 2.5a.
Answer: store B
Answer:
======================
<h3>Given sequence</h3>
<h3>To find</h3>
<h3>Solution</h3>
Since the given is the GP, find the common ratio in terms of given values:
Equate the two values and solve for x to find the missing term:
- x/ 25 = 874/x
- x² = 874*25
- x² = 21850
- x = √21850
- x = 5√874
