Answer:
No solutions
Step-by-step explanation:
Simplify both sides of the equation as much as possible:
9r + 5 - 4 = 4r + 5r - 12
9r + 1 = 9r - 12
Both sides have "9r" which when cancel out, leave the equation as:
+1 = -12
This means there are no solutions.
Answer:
A)
Step-by-step explanation:
We can use logarithm properties to write it as:
On removing it gives:
Taking square root both sides.
Solving for we get:
and
Subtracting by 1 to both sides of both the above equations.
and
and
So we have got two solutions for the logarithmic equation.
Now we check the validity of the solutions by plugging values in the equation
Plugging
[As ]
So, thats a valid solution.
Plugging
As is undefined, so is not a valid solution which means its extraneous.
Answer: 24
Step-by-step explanation:
Number of marbles in jar = 32
Let blue marbles be represented by b.
Since there are three times as many green marbles as blue. This means that green will be = 3 × b = 3b
We then add them together. This will be:
3b + b = 32
4b = 32
b = 32/4
b = 8
There are 8 blue marbles
Since green is 3× blue. Therefore,
Green = 8 × 3 = 24 marbles
The answer would be 99, because because if you remove the decimals and the 0's you get 99.
