Answer:
Step-by-step explanation:
x + 70 = 180 {Linear pair}
x = 180 - 70
x = 110
y + 82 = 180 {linear pair}
y = 180 -82
y = 98
x - 4 = 110 - 4 = 106
2y - 40 = 2*98 - 40
= 196 - 40
= 156
Answer: its the last answer 125 is not a perfect square it leads to a decimal
Step-by-step explanation:
Answer:
The number of bicycle that store sell each month to break even is 13 bikes .
Step-by-step explanation:
Given as :
The operation cost of bicycle store = $2400
The cost of payment by store at average rate = $60 per bike
The average selling price of each bike = s.p = $120 per bike
Let The number of bicycle that store sell each month to break even = n bikes
<u>According to question</u>
The operation cost of bicycle store = (cost of payment by store at average rate + average selling price of each bike ) × number of bicycle that store sell each month to break even
i.e ($60 per bike + $120 per bike) × n bikes = $2400
Or, ($180 per bike) × n bikes = $2400
∴ 180 n = 2400
Or, n = 
i.e n = 13.333 ≈ 13
So, The number of bicycle that store sell each month to break even = n = 13 bikes
Hence, The number of bicycle that store sell each month to break even is 13 bikes . Answer
