All you have to do is isolate m. We have to move all terms except m to the other side.
15 + 5m = 415
We have to cancel out the numbers. 15 is being added so we subtract it from both sides.
15 - 15 + 5m = 415 - 15
5m = 400
5 is being multiplied so we divide it on both sides.
5m/5 = 400/5
m = 80
We can plug in to prove.
15 + 5(80) = 415
15 + 400 = 415
415 = 415
I did 2/27 which equals 0.074
So its basically 74
So to make it a percentage we need to move it 2 spaces=
7.4%
∠BDC and ∠AED are right angles, is a piece of additional information is appropriate to prove △ CEA ~ △ CDB
Triangle AEC is shown. Line segment B, D is drawn near point C to form triangle BDC.
<h3> What are Similar triangles?</h3>
Similar triangles, are those triangles which have similar properties,i.e. angles and proportionality of sides.
Image is attached below,
as shown in figure
∡ACE = ∡BCD ( common angle )
∡AED = ∡BDC ( since AE and BD are perpendicular to same line EC and make right angles as E and C)
∡EAC =- ∡DBC ( corresponding angles because AE and BD are parallel lines)
Thus, △CEA ~ △CDB , because of the two perpendiculars AE and BD.

Answer: The answer is 16+4x
Step-by-step explanation:
4*4 is 16 and 4*x is 4x since I can't add them together it would be 16+4x
Answer:
x = 911.25
Step-by-step explanation:
let the number be x
by putting the word problem in equation, we get :
- 80/100 × x = 135/100 ×540
- 4/5 × x = 135/10 × 54
- x = 135/10 × 54 × 5/4
- x = 911.25
