Mike and Alice recycled 147 bottles altogether. Mike recycled 6 times as many bottles as Alice. How many bottles did Alice recyc
ValentinkaMS [17]

Answer:

The number of bottles recycle by Alice is 21.

Step-by-step explanation:

Given:

Mike and Alice recycled 147 bottles altogether. Mike recycled 6 times as many bottles as Alice.

Now, to find the quantity of bottles Alice recycle.

Let the number of bottles recycle by Alice = x.

And the number of bottles recycled by Mike = 6x.

So, according to question:

x+6x=147

⇒7x=147

<em>Dividing both sides by 7 we get:</em>

⇒x=21.

Therefore, the number of bottles recycle by Alice is 21.

What is the true solution to 3 in 2 + in 8 = 2 in (4x)
11Alexandr11 [23.1K]
The first step for solving this equation is to determine the defined range.
3㏑(2) + ㏑(8) = 2㏑(4x), x > 0
Write the number 8 in exponential form.
3㏑(2) + ㏑(2³) = 2㏑(4x)
Using ㏑(a^{x}) = x × ㏑(a),, transform the expression.
3㏑(2) + 3㏑(2) = 2㏑(4x)
Now collect the like terms on the left side of the equation.
6㏑(2) = 2㏑(4x)
Switch the sides of the equation.
2㏑(4x) = 6㏑(2)
Using x × ㏑(a) = ㏑(a^{x}),, transform the expression on the left side of the equation.
㏑((4x)²) = 6㏑(2)
Using x × ㏑(a) = ㏑(a^{x}),, transform the expression on the right side of the equation.
㏑((4x)²) = ㏑(2^{6})
Since the bases of the logarithms are the same,, you need to set the arguments equal.
(4x)² = 2^{6}
Take the square root of both sides of the equation and remember to use both the positive and negative roots.
4x = +/- 8
Now separate the equation into 2 possible cases.
4x = 8
4x = -8
Solve the top equation for x.
x = 2
Solve the bottom equation for x.
x = 2
         , x > 0
x = -2
Lastly,, check if the solution is in the defined range to find your final answer.
x = 2
This means that the correct answer to your question is x = 2.
