Today, both the wrestling and basketball team were scheduled to have practice in gym. Whoops! The wrestling team practices every 4 days and basketball team practices in the gym every 5 days. In how many days will they both be practicing in the gym on the same day?

  20 days

Step-by-step explanation:

The number of days will be a multiple of both 4 and 5. The smallest such multiple is called the "least common multiple" (LCM). One way to figure the LCM is to divide the product of the numbers by their greatest common factor. Since 4 and 5 have no common factors, the LCM is 4·5 = 20.

Both teams will be practicing on the same day again in 20 days.

x = 12

y = 15

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
