Runner = 5 mph
bicyclist...4 times the runner....4(5) = 20 mph

20 - 5 = 15 mph <== the difference

two crates contain Apple's, pears and oranges. there are 184 apples and pears in crate one and 248 apples and oranges in the sec

Ray Of Light [21]

Answer: There are 152 apples.

The explanation is shown below:

- You need to write the following three equations, where $a$ is the the number of apples, $p$ is the number of pears and $o$ is the number of oranges:

1) $a+p=184$

2) $a+o=248$

3) $o=3p$

- You must substitute the equation 3) into the equation 2):

$a+3p=248$

- Now, you need to solve for $p$ in the equation 1) and then you must substitute it into $a+3p=248$ :

$p=184-a$

$a+3(184-a)=248$

- Solve for $a$ , as following:

$a+552-3a=248\\-2a=-304\\a=\frac{-304}{-2}\\a=152$

- Therefore, there are 152 apples.

Which exponential equation is equivalent to the logarithmic equation below?

julsineya [31]

Answer:

$\implies\boxed{ 10^a = 300 }$

Step-by-step explanation:

We are provided logarithmic equation , which is ,

$\implies log_{10}^{300}= a$

Here we took the base as 10 , since nothing is mentioned about that in Question .

Say if we have a expoteintial equation ,

$\implies a^m = n$

<u>In</u><u> </u><u>logari</u><u>thmic</u><u> </u><u>form</u><u> </u><u>it</u><u> </u><u>is</u><u> </u><u>,</u><u> </u>

$\implies log_a^n = m$

Similarly our required answer will be ,

$\implies\boxed{ 10^a = 300 }$
