Find all the missing values to make the equation true
1 answer:
The missing value in the logarithm are as follows:
- log₃ 7 - log₃ 2 = log₃ (7 / 2)
- log₉ 7 + log₉ 4 = log₉ 28
- log₆ 1 / 81 =
- - 4 log₆ 3
<h3>How to solve logarithm?</h3>
Using logarithm rule,
logₐ b - logₐ c = logₐ (b / c)
logₐ b + logₐ c = logₐ (b × c)
Therefore,
log₃ 7 - log₃ 2 = log₃ (7 / 2)
log₉ 7 + log₉ 4 = log₉ (7 × 4) = log₉ 28
log₆ 1 / 81 = log₆ 81⁻¹ = log₆ 3⁻⁴ = - 4 log₆ 3

Answer:
There are two bricks in the bag.
Step-by-step explanation:
1 1/3 can be written as 4/3 bricks in a bag.
(4/3)/(2/3) = 2
There are two bricks in the bag.
2y - 3/5 = 1/2
2y = 1/2 + 3/5
- Let's make the two fractions have common denominators.
- Multiply 1/2 by 5/5 and 3/5 by 2/2.
- 1/2 * 5/5 = 5/10
- 3/5 * 2/2 = 6/10
2y = 5/10 + 6/10
Add the two fractions.
2y = 11/10
Divide both sides by 2.
- 11/10 ÷ 2
- Use the Keep, Change, Flip method.
- Keep 11/10, change ÷ to ×, and flip the 2 (reciprocal).
- 11/10 × 1/2 = 11/20
y = 11/20
