One positive number is one-fifth of another number. The difference between the two numbers is 144, find the numbers.
liubo4ka [24]

Answer:

36, 180

Step-by-step explanation:

x = y/5, so y = 5x

y - x = 144

5x - x = 144

4x = 144

x = 144/4 = 36

y = 5x = 5*36 = 180

The two numbers are 36 and 180

Erika is working on solving the exponential equation 50x = 17; however, she is not quite sure where to start. using complete sen
Kryger [21]

Erika is working on solving the exponential equation 50^x = 17; The solution is x = 0.7242.

<h3>What is logarithm?</h3>

When you raise a number with an exponent, there comes a result.

Let's say you get

a^b = c

Then, you can write 'b' in terms of 'a' and 'c' using a logarithm as follows

b = \log_a(c)

'a' is called base of this log function. We say that 'b' is the logarithm of 'c' to base 'a'

Erika is working on solving the exponential equation 50^x = 17;

however, she is not quite sure where to start.

The equation is

50^x = 17\\

By taking the log both sides

log_a b = x\\\\a_x = b

By using the base formula

log_0 y = \dfrac{logy}{log b}

So, log_{50} 17= x\\\\

x = \dfrac{log17}{log 50}

x = 0.7242

Jason rolls the die 14 times. What is the experimental probability that he will roll a 2
Vaselesa [24]
There’s 14 rolls. The probability he lands on a 2 would be 2/14. Once you simplify it it would give you a probability of 1/7

Explain why you can subtract exponents when you are dividing two powers with the same base.
masya89 [10]

When you divide numbers, you make the value smaller.  So subtract the exponents will make the value with that base smaller.
