Which statement is true about 143? A. It is a prime number. B. It is a composite number. C. It is a whole number that is neither prime nor composite. D. It is not a whole number.
Answer:
B. It is a composite number.
Step-by-step explanation:
143 can be divided by 11 and 13 making it a composite number.
The number 143 is a composite number due to having more than two factors.
The factors of the number 143 are 1, 11 and 13.
What is the difference between a prime number and a composite number?Prime number has only two factors i.e. 1 and the number itself while composite numbers can have more than two factors.
143 = 1*11*13
Since the number 143 has 3 factors i.e. 1, 11, and 13.
So, The number 143 is a composite number.
Therefore, The number 143 is a composite number due to having more than two factors.

An online streaming service deducts $7 from Serena’s account every month of a year. After 1 year, how much do the streaming service fees change Serena’s account?
Answer:
$84
Step-by-step explanation:
This is a super simple question. All you have to know is how much money will be charged a month, and how many months there are in a year. Just simply multiply 7 by 12 as the streaming service is charging 7 dollars a month and there are 12 months in a year. After you multiply the two numbers, you should end up with 84 dollars charged after 1 year.

A construction worker lowers a 100-foot rope from the top of a building. Another worker attaches the bottom of the rope to the ground, 23 feet from the base of the building. What is the height of the building rounded to the nearest foot?
Answer:
97 ft
Step-by-step explanation:
The Pythagorean theorem is useful for working problems like this. It tells you the relationship between side lengths and the hypotenuse of a right triangle.
Here, the building is presumed to be perpendicular to the ground, so the 100' rope is the hypotenuse of a triangle with legs equal to 23' and the height of the building (b).
23² +b² = 100²
b = √(10000 -529) ≈ 97.32
The height of the building is about 97 feet.

The equation of the line is 7x+2y = 1
What is an equation of a line?The equation of a line is linear in the variables x and y which represents the relation between the coordinates of every point (x, y) on the line. i.e., the equation of line is satisfied by all points on it.
Given that a line is passing through two points J(-3, 11) and K(1, -3). we need to find the equation of line JK,
So, we know that the equation of a line passing from two points (x₁, y₁) and (x₂, y₂) is =
y-y₁ = y₂-y₁/x₂-x₁ (x-x₁)
Here, (x₁, y₁) and (x₂, y₂) = J(-3, 11) and K(1, -3)
Therefore, the equation of the line =
y-11 = -3-11 / 1+3 (x+3)
y-11 = -7/2(x+3)
Multiply by 2,
2y-22 = -7(x+3)
2y-22 = -7x-21
7x+2y = 1
Hence the equation of the line is 7x+2y = 1

Four less than 5 times a number is the same as 26 more than twice the number.
Answer:
False
Step-by-step explanation:
5x - 4 versus 2x + 26
Imagine x equals 1, then the equations would be:
5(1) - 4 and 2(1) + 26
1 and 28 are not equivalent.
Another example would be x = 6
5(6) - 4 and 2(6) + 26
26 and 38 are not equivalent.
No matter what you replace x with, the expressions are never equal.
Solve the system of equations using any method. 2X – Y + Z = – 2, 6X + 3Y – 4Z = 8, – 3X + 2Y +3Z = – 6
Answer:
Z = - 2, Y = 0, X = 0
Step-by-step explanation:
2X – Y + Z = – 2
6X + 3Y – 4Z = 8
– 3X + 2Y +3Z = – 6
isolate "X" in the first equation
2X - Y + Z = - 2 => isolate "2X"
2X = - 2 - Z + Y => divide either side by 2
X = - 1 - Z/2 + Y/2
substitute this value of X in the second two equations (applying the substitution method here)
6(- 1 - Z/2 + Y/2) + 3Y - 4Z = 8,
6Y - 7Z - 6 = 8
- 3(- 1 - Z/2 + Y/2) + 2Y +3Z = - 6,
Y + 9Z + 6/2 = - 6
isolate Y in the second equation (6Y - 7Z - 6 = 8) and substitute in the third equation (Y + 9Z + 6/2 = - 6)
6Y - 7Z - 6 = 8 => isolate 6Y
6Y = 14 + 7Z => divide either side by 6
Y = 7Z + 14/6 => substitute in second equation
7Z + 14/6 + 9Z + 6/2 = - 6 => solve for Z
61Z + 50/12 = - 6, Z = - 2
substitute the value of Z into the equations "Y = 7Z + 14/6" and using the value of Y and Z, substitute into "X = - 1 - Z/2 + Y/2"
Y = (7(- 2) + 14)/6 = 0 / 6
= 0
X = - 1 - (- 2)/2 + 0/2 = - 1 - (-1) + 0
= - 1 + 1 + 0 = 0
