Answer:


w+b=150

Or


2b+b=150

Explanation:

Given : An orchestra has twice as many woodwind instruments as brass instruments. There are a total of 150 brass and woodwind instruments.

To Find: Write two different addition equations that describes this situation.

Solution:

Let w be the woodwinds instruments..

Let b be the brass instruments.

We are given that An orchestra has twice as many woodwind instruments as brass instruments.

So,
w = 2b

We are given that There are a total of 150 brass and woodwind instruments.

So,
w+b=150

Or


2b+b=150

Hence two different addition equations that describes this situation are :


w+b=150

Or


2b+b=150

Answer: The two different addition equations that describes the given situation are,

w = 2 b

b + w = 150

Explanation:

Here, w represents the number of woodwinds and b represents the number of brass instrument.

Since, There are twice as many woodwind instruments as brass instruments,

⇒ w = 2b

And, The total number of instruments = 150

⇒ w + b = 150

Hence, the equations that shows the given situation are,

w = 2 b, b + w = 150
