1) Billy walks 15 miles every day to soccer practice, and catches a ride home from his grandma. Billy had 5 practices last week.

nignag [31]

1 ) Billy walks 15 miles every day to soccer practice and he had 5 practices last week.

We know that, 1 mile = 1760 yards

So, 15 miles = (15× 1760) yards = 26400 yards

Thus the total distance walked in 5 practices will be: $(26400*5)yards = 132000 yards$

2) Mark's current age is $t$ years

So, his age was in 10 years ago $=(t-10)years$

Given that, his current age is 3 times his age 10 years ago.

So, the equation to represent this situation will be : $t= 3(t-10)$

stepan [7]

Answer: 5=log_{2}(32)5=log

(32)

Step-by-step explanation:

1. By definition, you have if y=b^{x}y=b

, then x=log_{b}(y)x=log

(y)

2. Keeping this on mind, you must follow the proccedure shown below:

- You have that:

2^{5}=322

=32

Where:

\begin{lgathered}x=5\\y=32\\b=2\end{lgathered}

x=5

y=32

b=2

- Substitute values into x=log_{b}(y)x=log

(y) . Then, you obtain:

5=log_{2}(32)5=log
