Answer:

  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.

What is the value of x innthe equation 1.5(x+4)-3=4.5(x-2)
daser333 [38]

~~~~~~1.5(x+4)-3 = 4.5(x-2)\\\\\implies 15(x+4) -30 =45(x-2)~~~~~~~~;[\text{Multiply both sides by 10]}\\\\\implies 3(x+4)-6=9(x-2)~~~~~~~~~~;[\text{Divide both sides by 5]}\\\\\implies 3x+12-6=9x-18\\\\\implies 3x+6=9x-18\\\\\implies 9x-3x = 18+6\\\\\implies 6x = 24\\\\\implies x = \dfrac{24}6\\\\\implies x =4
