You mean 60%of 5 1/2? that makes more sense...

i would do it like this:

(60% is the same as

(so that there is no confusion, i've put it into an improper fraction

now we can multiply:

which is 3.3.

so 60% of 5 and a half is 3.3.

**Answer:**

30 - (20 ÷ x) ⋅ 4

**Step-by-step explanation:**

The solution set of the **inequality** x ≥ - 4 using **set builder notation** and **interval notation** is {x | x ∈ Z, - 4 ≤ x ≤ ∞ } and [ - 4, ∞ ) respectively.

An **inequality** in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way.

A set can be represented by its elements or the properties that each of its members must meet can be described using **set-builder notation**.

**Interval Notation**: A set of real numbers known as an interval contains all real numbers that fall inside any two of the set's numbers.

Consider the inequality,

x ≥ - 4

In the number line, the value of x is equal to and greater than - 4 increasing to infinity.

Therefore,

The solution set using the **set builder notation** is:

{x | x ∈ Z, - 4 ≤ x ≤ ∞ }

The solution set of the inequality using the interval notation is:

[ - 4, ∞ )

**Answer: Jerry walked 2 7/20 miles to get to the park**

**Step-by-step explanation:**

1/2 of 3 1/2

1/2 of 7/2 = 7/4

7/4 + 3/5

Find the LCM of the denominator

LCM of 4 and 5 = 20

35/20 + 12/20 = 47/20 = 2 7/20

Jerry walked 2 7/20 miles to get to the park

A(-5,5)

B(4,5)

C(2,0)

D(-5,-2)
