b+4=2b-5, could someone help me with this question please, step by step because I have a quiz in math on friday, thank you!
svet-max [94.6K]
<span>"Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-2b' to each side of the equation. 4 + b + -2b = -5 + 2b + -2b Combine like terms: b + -2b = -1b 4 + -1b = -5 + 2b + -2b Combine like terms: 2b + -2b = 0 4 + -1b = -5 + 0 4 + -1b = -5 Add '-4' to each side of the equation. 4 + -4 + -1b = -5 + -4 Combine like terms: 4 + -4 = 0 0 + -1b = -5 + -4 -1b = -5 + -4 Combine like terms: -5 + -4 = -9 -1b = -9 Divide each side by '-1'. b = 9 Simplifying b = 9"- geteasysolution.com</span>

Reduce a ratio 3/4in: 3/16 ft
Dmitrij [34]

Answer:

4in : 1ft

Step-by-step explanation:

We start with:

3/4 in = 3/16 ft

This means that the length of 3/4 inches is the same as the length of 3/16 feet.

To reduce this, we can start by dividing by 3 in both sides of the equation:

(3/4)/3 in = (3/16)/3 ft

1/4 in = 1/16 ft

Now we can multiply both sides by 16:

16/4 in = 16/16ft

4 in = 1ft

now we reduced the ratio to:

4in : 1ft
