an integer is a whole number that is positive ,negative or zero
Examples of integers: 1, 2, -5, -18, 20
Not Integers: 0.2, 9.15, 2/3
Final answer:
The division of -16 by 8 results in -2, which is an integer because it has no decimal component. Therefore, -16/8 is an integer.
Explanation:
The question is whether -16/8 is an integer. To determine this, we simply perform the division: -16 divided by 8 equals -2. Since -2 has no decimal component, it is indeed an integer. Integers are whole numbers that can be positive, negative, or zero, but do not include fractions or decimals. Examples of integers include -8, -6, -2, 0, 4, and 12. In this case, -16/8 simplifies precisely to -2, which is an integer.

Answer:
(-1, -1.5)
Step-by-step explanation:
A coordinate is a point (a single place) on a graph. Coordinates can be recorded as (#, #).
The first number is the one on the x-axis (left/right) and the second number is the one on the y-axis (up/down). (x, y) The middle point, where the x-axis and y-axis meet is called the origin, and is at (0,0).
The point that marks the campground is at -1 on the x-axis and -1.5 on the y axis.
Because the y-axis has two lines for every whole number, the line in between is the halfway mark and counts as a 0.5 increment.

Step-by-step explanation:
It's where the line is straight. What's the second question?
Answer:
0.75 (45 mins) for both
Step-by-step explanation:
It's because the rest is the time where no activity is happening (the straight line). That line when measured from its start to end is mins 45 to mins 90, and when subtracted, gives 45 mins. For the initial ride it is from where the line moves upward until it stops. That goes from mins 0 to mins 45 ad when subtracted gives 45 mins.

Which expression and value of six less than the quotient of a number and two increased by ten when n=8
Answer:
The expression is [tex]\frac{n}{2}-6+10[/tex]
For n=8 the value of the expression is 8
Step-by-step explanation:
Let
n -----> the number
we know that
"six less than" means we're subtracting 6:
- 6
"The quotient" means division. "Of a number and 2" Usually the numerator is listed first:
n/2
"increased by ten" means we're adding 10:
+10
substitute
[tex]\frac{n}{2}-6+10[/tex]
For n=8
substitute the value of n in the expression
[tex]\frac{8}{2}-6+10[/tex]
[tex]4-6+10=8[/tex]
Answer:
Expression would be [tex]\frac{n}{2}-6+10[/tex]
Value would be 8.
Step-by-step explanation:
Here, n represents the unknown number,
∵ The quotient of n and 2 = [tex]\frac{n}{2}[/tex]
6 less than [tex]\frac{n}{2}[/tex] = [tex]\frac{n}{2}-6[/tex]
[tex]\frac{n}{2}-6[/tex] increased by 10 = [tex]\frac{n}{2}-6+10[/tex]
Thus, the required expression would be,
[tex]\frac{n}{2}-6+10[/tex]
When n = 8,
[tex]\frac{8}{2}-6+10=4-6+10=8[/tex]
Maya has 3 times as many dimes as nickels. She has 4 more quarters than nickels. if she has a total of $9.40, how many of each type of coin does she have?
Answer: nickels = 14, dimes = 42, quarters = 18
Step-by-step explanation:
Let n represent nickels which has a value of $0.05
Let d represent dimes which has a value of $0.10
Let q represent quarters which has a value of $0.25
It is given that:
n = n
d = 3n
q = n + 4
and their total value is $9.40 ⇒ n + d + q = $9.40
Use substitution to find the quantity of nickels:
.05(n) + .10(3n) + .25(n + 4) = 9.40
5n + 10(3n) + 25(n+4) = 940 multiplied by 100
5n + 30n + 25n + 100 = 940 distributed
60n + 100 = 940 added like terms
60n = 840 subtracted 100
n = 14 divided by 60
n = 14
d = 3n
= 3(14)
= 42
q = n + 4
= (14) + 4
= 18

Step-by-step explanation:
Mr. Yueng graded his students’ math quizzes.
Students came up with four different answers when solving the equation x3 = 22.
Which answer is correct?
A. x=22 3
B. x=22−−√3
C. x=±22−−√3
D. x=22−−√
For this case we must solve the following equation:
[tex]x ^ 3 = 22[/tex]
If we apply cubic root to both sides of the equation, then we eliminate the exponent on the left side:
[tex]\sqrt [3] {x ^ 3} = \sqrt [3] {22}\\x = \sqrt [3] {22}[/tex]
That is the exact solution of the equation. Its decimal solution is given by:
[tex]x = \sqrt [3] {22} = 2.8020[/tex]
ANswer:
The solution to the equation is [tex]x = \sqrt [3] {22} = 2.8020[/tex]
Option B. x = [tex]\sqrt[3]{22}[/tex] is the correct answer, by solving x³ = 22, where we found the cube root of 22. Other options are incorrect.
We will determine a number that, when raised to the power of 3, equals 22.
Option A: x = [tex]22^{3}[/tex] is incorrect because this represents 22 cubed, not the cube root of 22.Option B: x = [tex]\sqrt[3]{22}[/tex] is correct because it accurately represents the cube root of 22.Option C: x = ± [tex]\sqrt[3]{22}[/tex] is incorrect because cube roots can include negative values, but in the context of this problem we are looking for a single, positive value.Option D: x = [tex]\sqrt{22}[/tex] is incorrect because this represents the square root of 22, not the cube root.Therefore, the correct choice is option B. x = [tex]\sqrt[3]{22}[/tex]
Corrected question:

x/3+6-2x=-6
Answer:
36/5
Step-by-step explanation:
x/3 + 6 -2x = -6
multiply the whole equation by 3 to get rid of the denominator of the first x term.
x+18-6x = -18
move x terms to one side and numerical terms to the other, subtract 18 from both sides in this case
x+18-6x-18=-18-18
x-6x = -36
simplify
-5x = -36
divide both sides by -5 to isolate x
x = -36/-5
=36/5

here, we have,
given that,
x y
8 4
12 8
14 10
17 13
In order to solve, we replace the values of x in the functions in at least two points, we then compare if the answers correspond with the y-components. From this, we will have that the function that models the table is:
y = x - 4
The table looks like this:
x = 8 => y = 8-4 = 4
x = 12 => y = 12 - 4 = 8
x = 14 => y = 14 - 4 = 10
x = 17 => y = 17 - 4 = 13
Hence, The solution is, y = x - 4 , is the function equation for the input/output table.

Is 257 divisibil by 6
Step-by-step explanation:
6 is divisible by 2 and 3 (6 = 2 · 3).
257 is not divisible by 2 and 3 (257 is a prime number).
Therefore 257 is't divisible by 6.
Final answer:
257 is not divisible by 6 because it is not even.
A number must be even and the sum of its digits divisible by 3 to be divisible by 6.
Explanation:
To determine if 257 is divisible by 6, we need to check if it satisfies the criteria for divisibility by 6.
A number is divisible by 6 if it is divisible by both 2 and 3.
For divisibility by 2, the number must be even, which means it should end in 0, 2, 4, 6, or 8. For divisibility by 3, the sum of the digits of the number must be divisible by 3.Examining 257, we see that it ends with a 7, which is not an even number.
So it does not meet the criterion for divisibility by 2.
Therefore, 257 is not divisible by 6.

25 POINTS!
Answer:
the answer is y = -3x + ( -0.25)
Step-by-step explanation:
The equation of a line with a slope of -3 passing through the point (1.25, -4) can be derived by using the point-slope form (y - y1 = m(x - x1)). Substituting the given values, we get the line's equation as y = -3x - 0.25.
Explanation:The given problem requires us to write the equation of a line in either point-slope form or slope-intercept form. We are provided with a bit of information to get started: the slope of the line (-3) and a point the line passes through (1.25, -4).
The point-slope form of a line's equation is: y - y1 = m(x - x1), where (x1, y1) are coordinates of a point on the line and m is the slope. Substituting the given values, we get y - (-4) = -3(x - 1.25), which simplifies to y + 4 = -3x + 3.75. Finally, rearranging, we get the slope-intercept form: y = -3x - 0.25.

which aet of processes must occur to form soil
Answer:
Step-by-step explanation:
To form soil, the two processes which must occur are erosion and weathering, so the correct answer here is B. Soil formation is a continuous process, but also one which takes a long time. It can sometimes more than five hundred years for 1cm of soil to form.
The formation of soil is a complex process that involves various physical, chemical, and biological processes acting over long periods of time.
Some of the key processes involved in soil formation include:
1. Weathering: Weathering is the breakdown of rocks and minerals into smaller particles due to exposure to physical, chemical, and biological agents such as water, wind, temperature fluctuations, plant roots, and microorganisms.
2. Erosion and Transportation: Once rocks and minerals are weathered, the resulting particles are transported by agents such as water, wind, ice, and gravity. Erosion refers to the movement of soil particles from one place to another, while transportation involves the movement of these particles over long distances.
3. Deposition: Deposition occurs when transported soil particles settle out of suspension and accumulate in a new location. Deposition can occur in various environments, such as river deltas, floodplains, glacial moraines, and coastal areas.
4. Organic Matter Accumulation: Organic matter, derived from decaying plant and animal remains, accumulates on the soil surface or mixes with mineral particles. Organic matter plays a crucial role in soil fertility, structure, and nutrient cycling.
