We have two numbers that add to 42.... Call the larger number X and the smaller number Y X+Y = 42 We are told that Y is 12 less than X so Y = X-12 Substitute X-12 in place of Y in the original equation giving X + X -12 = 422X - 12 = 42Add 12 to both sides2X = 54Divide both sides by 2X = 27 Y = X-12 = 27 - 12 = 15 Our two numbers are 27, 15

Solve log525 = x 2 1/2 -2

elixir [45]

Answer:

x = 1/2

Step-by-step explanation:

The equation in correct format is:

$log_{5}(25)=x$

We have to solve this logarithmic equation to find the value of x. This can be done by using the rules of logarithm i.e the power rule and same base rule shown below:

$log(a)^{b}=b \times log(a)\\\\log_{a}(a)=1$

Using these rules on our equation, we get:

$log_{5}(25)=x\\\\log_{5}(5^{\frac{1}{2} })=x\\\\ \frac{1}{2} log_{5}(5)=x\\\\ \frac{1}{2} (1)=x\\\\ x=\frac{1}{2}$

Thus the value of x would be 1/2

Answer: The cost for 20 people equals $180.

Step-by-step explanation:

Given: It costs $100 to rent the bowling alley, plus $4 per person.

The cost for any number (n) of people can be found using the expression

$100+4n$

We can find the cost for 20 people by substituting n=20 in the above expression, we get

$100+4(20)=100+80=180$

Hence, The cost for 20 people equals $180.
