Which expression is equivalent to b + b - 0.56b?
Alexxx [7]
Hey there!

“Which expression is equivalent to b + b – 0.56b?”

• “b” or any other letter value is considered an “unknown number” so usually we label it/them as an invisible 1

• COMBINE the LIKE TERMS

(b + b – 0.56b)

(1b + 1b – 0.56b)
1b + 1b = 2b
2b – 0.56b = 1.44b

• Therefore, b + b – 0.56b is equivalent to 2b + 0.56b

Possible answer that you could be looking for: 2b + 0.56b ☑️

Good luck on your assignment and enjoy your day!

Answer:

180 cm³

Step-by-step explanation:

A glass is 1/3 full. Then 75cm³ of orange juice is poured in. The glass is now 3/4 full. What is the total volume of the glass?

Let

x = total volume of the glass

1/3x + 75 = 3/4x

75 = 3/4x - 1/3x

75 = 9x-4x/12

75 = 5/12x

x = 75 ÷ 5/12

x = 75 × 12/5

= 900/5

= 180 cm³

x = 180 cm³
