42 minutes
Step-by-step explanation:
There are 60 minutes in an hour and we want to find 0.7 of that. Of means multiply so we multiply 60 by 0.7 and we get 42 minutes.
The value of the variable x will be 7 that holds true for the equation.
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
A number is 5 more than 3 times another number.
The sum of the two numbers is 33.
Let the number be x.
Then the another number will be 3x + 5.
Then the equation will be
x + 3x + 5 = 33
Then the value of x will be
4x + 5 = 33
4x = 28
x = 7
Then the value of the variable x will be 7 that holds true for the equation.
