10(2x - 8)
^ ^
20x - 80
Since there are no like terms, the answer will be 20x - 80. Hope I helped.
Let selling price = SP and cost price = CP
He makes 20 % on selling price means = >
(sp-cp) / sp = 20 % = 20/100 = 0.2
(sp - cp) / sp = 0.2
1 - cp/sp = 0.2
1 - 0.2 = cp/sp
0.8 = cp/sp
Reversing 1 / 0.8 = sp/cp = 1.25
We need to find profit on cost price means =
=(sp-cp)/ cp
= sp/cp - 1 = 1.25 - 1 = 0.25
Means 25 % profit on cost price : Answer
Hope that will help :)
Answer:
angles of the figure
Step-by-step explanation:
not sure but
<h3>Given : </h3>
- Radius of circle = 7 inches
<h3>To Find : </h3>
- Circumference of circle = ?
<h3>Solution :</h3>
We are given radius, r = 7 inches
We know that :
Circumference = 2πr
⟹ Circumference = 2π × 7 inches
⟹ Circumference = 14π inches
Hence, circumference of circle is 14π inches.
