Answer:
99
Step-by-step explanation:
-6-5[-4-(6+12)]+(-5)
Following PEMDAS
We work the parentheses from the inside out
-6-5[-4-(18)]+(-5)
-6-5[-22]+(-5)
Now we multiply
-6+110 -5
Now we add and subtract from left to right
104 -5

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:
5 tulips.
Step-by-step explanation:
Given:
The expression for the cost of the tulips is 
Where, 
is the number of tulips.
Now, Joanna has 
.
So, number of tulips that can be bought with the above amount can be obtained by substituting for cost. This gives,
.
As the number of tulips cannot be in decimals or fractions, so the maximum number of tulips that can be bought will be 5.
Answer:
y = - 49
Step-by-step explanation:
Given
7x - 2y = 35 ← substitute x = - 9 into the equation
7(- 9) - 2y = 35, that is
- 63 - 2y = 35 ( add 63 to both sides )
- 2y = 98 ( divide both sides by - 2 )
y = - 49
