Answer: x < 2
Step-by-step explanation:
The difference of x and 3 means subtract 3 from x is less than -1, we represent the question in the expression below:
X - 3 < -1
X < -1 + 3
X< 2
He would sell 57 papers in 3 hours.
38÷2= 19
So 19 papers in one hour.
19×3= 57
Hope this helps! :)

The area of the triangle XYZ is 29.1 square units
Explanation:
Given that the measurements of the sides of the triangle XYZ are , and
We need to determine the area of the triangle XYZ
<u>Area of the triangle:</u>
The area of the triangle can be determined using the formula,
Substituting the values, we get,
Simplifying, we get,
Multiplying the terms, we get,
Dividing the terms, we have,
Rounding off to the nearest tenth, we get,
Thus, the area of the triangle XYZ is 29.1 square units.
The constant of proportionality represented by K will be 1/3 which is shown in the given graph.
<h3>What is the constant of proportionality?</h3>
Firstly, there is a proportional relationship.
Two values x and y are said to be in a proportional relationship if x = ky, where x and y are variables and k is a constant.
The constant k is called the constant of proportionality.
The proportional relationship between x and y can be written symbolically as
That middle sign is called a sign of proportionality.
In the given graph x line and y line have been graphed.
Since the relation between them has been represented by a straight line, so their relationship can be represented by
x = K × y
where K is the proportionality constant.
Now K =
=
= 1/3
therefore, the constant of proportionality will be 1/3.

Answer:
ZB= 39°
Step-by-step explanation:
complementary angles are angles that add up to equal 90
equation: 7x + 23 + 5x + 19 = 90
add like terms: 12x + 42 = 90
subtract 42 from both sides: 12x = 48
divide both sides by 12: x = 4
plug in the value of x to the equation for ZB: 5(4) + 19
simplify: ZB= 39°
