14 V = bdt. Solve the formula for de
d = b/tv
10
d = tłby
d = vbt
d = wbt
Answer:
[tex]d=\dfrac{V}{bt}[/tex]
Step-by-step explanation:
It is given that,
V = bdt i.e. V is equal to the product of b, d and t
We need to find the formula for d.
Dividing both sides of the given expression by bt
So,
[tex]\dfrac{V}{bt}=\dfrac{bdt}{bt}\\\\d=\dfrac{V}{bt},\ \text{bt in both denominator and numerator cancel out}[/tex]
Hence, [tex]d=\dfrac{V}{bt}[/tex] is the value of d.

Solve the inequality. 20<5/6w
Answer:
w>24
Step-by-step explanation:
Let's solve your inequality step-by-step.
20<5/6w
Answer: x>24
Step-by-step explanation:
To solve the inequality, we want to isolate w.
[tex]20<\frac{5}{6}w[/tex] [multiply both sides by 6/5]
[tex]w>24[/tex]
Now, we know that w>24 or 24<w.
