5x + 2(11-1) = 30
Solve the equation/Explain each step

2.

Step-by-step explanation:

5x + 2(11-1) = 30

First, solve the ones inside the bracket:

11 - 1 = 10

Next, multiply the number inside the bracket by the number next to bracket:

2 × 10 = 20

The equation will now be:

5x + 20 = 30

Since 5x and 20 are not like terms, carry +20 over to the other side making it 30 - 20:

5x = 30 - 20

5x = 10

Now, divide both sides by the coefficient of x (5):

5x/5 = 10/5

x = 2

The answer to the equation is 2.

the first one, all those points on the line just make a strait line.

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
