A. -120
B. -20
C. 20
D. 120
Answer:
C. 20
Step-by-step explanation:
10|7−x| here we are asked to find the absolute value.
x is given as 5 so if we just rewrite the expression:
10|7-5| = 20 because absolute value cannot be negative.

What is greatest common factor?The biggest number, which is the variable of at least two number is known as the Best Normal Element (GCF). It is the biggest number (factor) that partition them bringing about a Characteristic number. When every one of the elements of the number are found, there are not many variables which are normal in both.
The factors of 6 and 9 are:
6 ⇒ 1, 2, 3 and 6
9 ⇒ 1, 3, 9
The greatest common factor here is therefore 3.
The factors of 18 and 15 are:
18 ⇒ 1, 2, 3, 6, 9 and 18
15 ⇒ 1, 3, 5, and 15
Greatest common factor is also 3
The factors of 3 and 9 are:
3 ⇒ 1 and 3
9 ⇒ 1, 3, 9
Greatest common factor here is also 3.

what is the equation of the line that passes through the points (-8,1) and (7,1)
Answer:
y = 1
Step-by-step explanation:
the equation of a horizontal line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line passes through
the line passes through (- 8, 1 ) and (7, 1 )
both with y- coordinates of 1 , then
y = 1 ← is the equation of the line

A polygon is regular if each of its sides has the same length. Find the perimeter of the regular polygon.
Based on the calculations, the perimeter of this regular polygon is equal to 7.5 units.
What is a polygon?A polygon can be defined as a two-dimensional geometric shape that comprises straight line segments and a finite number of sides. Also, some examples of a polygon include the following:
TriangleQuadrilateralPentagonHexagonHeptagonOctagonNonagonHow to determine the perimeter of this regular polygon?Since this polygon is a regular polygon with each of its sides being equal, we have:
3(x - 1) = 5x - 6
3x - 3 = 5x - 6
5x - 3x = 6 - 3
2x = 3
x = 3/2
x = 1.5.
The measure of each of its sides is given by:
3x - 3 = 5x - 6
3(1.5) - 3 = 5(1.5) - 6
4.5 - 3 = 7.5 - 6
1.5 = 1.5
Each side, a = 1.5 units.
Now, we can determine the perimeter of this regular polygon:
Perimeter of pentagon = 5a
Perimeter of pentagon = 5 × 1.5
Perimeter of pentagon = 7.5 units.

A tv show had 3.6 x 104 viewers in the first week and 4.1 x 104 viewers in the second week. determine the average number of viewers over the two weeks and write the final answer in scientific notation.
The computation shows that the average number of viewers over the two weeks will be 3.85 × 10⁴.
How to compute the value?From the information given, the tv show had 3.6 x 10⁴ viewers in the first week and 4.1 x 10⁴ viewers in the second week.
Therefore, the average number of viewers over the two weeks will be:
= (3.6 × 10⁴ + 4.1 × 10⁴)/2
= 7.7 × 10⁴/2
= 3.85 × 10⁴
Therefore, the average is 3.85 × 10⁴

Answer:
Step-by-step explanation:
Definitions
Prime number: A whole number greater than 1 that cannot be made by multiplying other whole numbers.
Prime Factorization: Prime numbers that multiply together to make the original number.
The first few prime numbers are: 2, 3, 5, 7, 11, 13, 17, ...
To find which prime numbers multiply together to make 252, begin by dividing 252 by the first prime number, 2:
⇒ 252 ÷ 2 = 126
As 126 is not a prime number, we need to divide again.
⇒ 126 ÷ 2 = 63
As 63 is not a prime number, and 63 is not divisible by 2, try dividing it by the next prime number, 3:
⇒ 63 ÷ 3 = 21
As 63 is not a prime number, divide again.
⇒ 21 ÷ 3 = 7
As 7 is a prime number, we can stop.
Therefore, 252 is the product of:
⇒ 252 = 2 × 2 × 3 × 3 × 7
As 2 and 3 appear twice, we can write these using exponents:
⇒ 252 = 2² × 3² × 7

a match box has length x cm, width x +1 cm and height 3 cm. express its surface area as a function of x
Answer:
2x² + 14x + 6
Step-by-step explanation:
A match box is in the shape of a right rectangular prism so we can use the formula for the surface area of such a solid
A=2(wl+hl+hw)
where l = length, w=width and h = height
Substituting l = x, w = x+1 and height = 3 we get
wl = x(x + 1) = x² + x
hl = 3x
hw = 3(x + 1) = 3x + 3
So A = 2( x² + x + 3x + 3x + 3)
A = 2(x² + 7x + 3)
A = 2x² + 14x + 6

The expression as a number in scientific notation is 4.2 * 10^5
How to write the expression as a number in scientific notation?The expression is given as:
quantity 7 times 10 cubed end quantity times quantity 5.4 times 10 to the fourth power end quantity all divided by quantity 9 times 10 squared
Rewrite properly as:
[7 * 10^3 * 5.4 * 10^4]/[9 * 10^2]
Evaluate the product of 7 and 5.4
So, we have:
[37.8* 10^3 * 10^4]/[9 * 10^2]
Evaluate the product of 10^3 and 10^4
So, we have:
[37.8* 10^7]/[9 * 10^2]
Evaluate the quotient of 37.8 and 9
So, we have:
[4.2 * 10^7]/[10^2]
Evaluate the quotient of 10^7 and 10^2
So, we have:
4.2 * 10^5
Hence, the expression as a number in scientific notation is 4.2 * 10^5

Emmett made sand art bottles to sell at his school's craft fair. He wanted to use 9 different colors of sand. So, he bought 1 pound of each color. Then, he filled as many 6-ounce bottles as he could. How many sand art bottles did Emmett make?
The number of bottles will be 24 bottles.
How to calculate the value?It should be noted that 1 pound = 16 ounces.
Since he bought 1 pound of each color, the total pounds will be:
= 1 × 9 = 9 pounds.
The number of sand art will be:
= 9 pounds / 6 ounce
= (9 × 16) / 6
= 24 bottles
