Step-by-step explanation:

  • v = speed of the wind

5(550 + v) = 6(550 - v)

2.750 + 5v = 3.330 - 6v

5v + 6v = 3.300 - 2.750

11v = 550

v = 550 ÷ 11

v = 50mph

Step-by-step explanation:

let v is the speed of the wind,

the equation of the speed:

(550 + v ) × 5 = (550 - v) × 6

2750 +5v = 3300 - 6v

11v = 3300 - 2750

11v = 550

v = 550/11

v = 50

therefore, the speed of the wind =

50 mph

In the figure shown e is the midpoint of segment bd and ae = ec . choose the correct statement(s)
forsale [732]

Answer:

Triangle ABE and triangle CDE are congruent by using SAS theorem.

Step-by-step explanation:

It is given that e is the midpoint of BD and AE=EC.

BE\cong DE             (E is midpoint of BD)

Angle AEB and angle CED are vertical opposite angle and the vertical opposite angles are always same.

\angle AEB\cong \angle CED

AE=EC                 (Given)

So by using SAS theorem of congruent triangles.

\triangle ABE\cong \triangle CED

Therefore triangle ABE and triangle CDE are congruent by using SAS theorem.
