5(x + 30)

x + 30 represents the number of minutes per day he practices
5 is the number of days he practices
so 5(x+30) = the total number of minutes he practices in 5 days

For example, if he practices the piano for 20 minutes per day and the violin for 30 minutes per day, he practices a total of 50 minutes per day. For 5 days that would be 5 x 50 = 250 minutes in 5 days.

Plug that into the equation
5(x+30) = 5(20+30) = 5(50) = 250

<h3>What is arithmetic?</h3>

Mathematical arithmetic is the study of the properties of the standard operations on numbers, such as addition, subtraction, multiplication, division, exponentiation, and root extraction. One of the branches of mathematics, 1a, deals with the application of addition, subtraction, multiplication, and division to nonnegative real numbers, sometimes including transfinite cardinals.

Given Data

Here, 5 in 15.2 is 1/10 times to 3.5.

The 5 in 3.5 is therefore $\frac{1}{10}$ times the 5 in 15.2, and likewise.
