Let x = quantity of bicycles
($160x) - ($80x) = $2800. To solve for x, we have to combine the terms on the left side.
$80x = $2800. Divide each side by $80.
x = 35.
35 bicycles must he sold each month to break even.
9<15mx-8<27
Divide the all by 3
3<5mx-8/3<9
After that times all by -1
-3<8/3-5mx<-9
Answer:
x = 22°
w = 30°
y = 30°
z = 52°
Step-by-step explanation:
From ΔACD,
AD is the diameter and ∠ACD is the angle subtended by the diameter.
Therefore, m∠ACD = 90°
By triangle sum theorem,
m∠DAC + m∠ACD + m∠CDA = 180°
w° + 90° + 60° = 180°
w = 180 - 150
w = 30°
AB║ED and AD is a transversal line.
Therefore, m∠BAD = m∠ADE
(w + 22)° = z°
30 + 22 = z
z = 52°
Since, ∠CEB and ∠BAC are the inscribed angles subtended by the same arc BC,
Therefore, m∠CEB = m∠BAC
x = 22°
Similarly, ∠CED and ∠DAC are the inscribed angles subtended by the same arc CD,
m∠CED = m∠DAC = 30°
y = 30°
Answer:
Step-by-step explanation:
Given:
The equation is given as:
Rearrange the above equation in standard quadratic equation of the form 
Adding 
on both sides, we get
Here, 
Now, we solve this using quadratic formula,
