Rules of adding integers
To add integers having the same sign, keep the same sign. and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.
Rules of subtracting integer
First, keep the first number (known as the minuend). Second, change the operation from subtraction to addition. Third, get the opposite sign of the second number (known as the subtrahend) . Finally, proceed with the regular addition of integers.
Rules of multiplying and dividing integers

Which of the following are solutions to the inequality below? Select all that apply.
The solution of the given inequality is m>12.
The given inequality is 6 < m/2.
What is a inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given inequality can be solved as follows:
6 < m/2
Multiply 2 to the given inequality.
That is, 6 × 2 < m/2 × 2
= 12<m
= m>12
Therefore, the solution of the given inequality is m>12.

The length of a rectangle is three times its width. the perImeter of the rectangle is 100 inches. What are the dimension of the rectangle
Answer:
width is 12.5 inches
length is 37.5 inches
Step-by-step explanation:
x is width, 3x is length,
Double each and make it equal to 100, ie. 2x+6x=100Divide everything by two, x+3x=50Combine x and 3x, 4x=50divide broth sides by 4x = 12.5Since x is width, width is 12.5Length is 3x, so 12.5 * 3 is 37.5A market ordered 140 apples packed in small bags.

5,000 books in the town's library of these 4,300are fiction. To find the percent of the books that are fiction, first set up the percent equation. Then find the percent.
Answer: 86%
Step-by-step explanation:
Number of books in the town's library = 5000
Number of books that are fiction= 4300
The percent of books that are fiction will be:
= 4300/5000 × 100
= 0.86 × 100
= 86%

The daily energy requirement for males is modeled by the chart below. Age (Years) (X) Energy Needed (Calories) (Y) 1 1100 2 1300 5 1800 8 2200 11 2500 14 2800 17 3000 Use the points (5, 1800) and (17, 3000) to determine a linear equation for the data.
Answer: y = 100x + 1300
Step-by-step explanation: Linear Equation is an equation whose graphic produces a line. It is of the form y = mx + B, in which m and B are real numbers.
The term m is also the slope or gradient of the equation, i.e., it shows the steepness of the line. While B is y-intercept, i.e., it is the point where the line touches the y-axis.
The slope is determined by:
[tex]m=\frac{y-y_{0}}{x-x_{0}}[/tex]
[tex]m=\frac{3000-1800}{17-5}[/tex]
m = 100
For the linear equation, use:
[tex]y-y_{1}=m(x-x_{1})[/tex]
and point (5,1800):
[tex]y-1800=100(x-5)[/tex]
[tex]y=100x-500+1800[/tex]
[tex]y=100x+1300[/tex]
The linear equation of daily energy requirement for males is [tex]y=100x+1300[/tex].

Answer:
u of the record for me and my family are doing well and that you have a meeting with the record for me and my family are doing well and that you have
Answer:
Step-by-step explanation:
Just rewrite y-3 = {(x - 1) as y-3 = m(x - 1). {(x - 1) is not valid.
Next, solve this y-3 = m(x - 1) for y:
Adding 3 to both sides yields y = m(x - 1) + 3, or:
y = mx - m + 3, or
y = mx + (-m + 3). This is in slope-intercept form.
If you choose m = 2, then the equation becomes
y = 2x +(-2 + 3), or:
y = 2x + 1
Note: to get a single answer to this question you must provide the m value.

A packet of crisp weighs 32 grams to the nearest gram. a multi-pack crisp contains 10 packets. work out the least and the greatest weighs of the multipack. ignore the weight of the multipack
Answer:
Least weight of multipack :
31.5 * 10 = 315g
Highest weight of multipack :
32.4 * 10 = 324g
Step-by-step explanation:
Weight of a packet of crisp to the nearest gram = 32 g
The least value of the weight of actual packet = 31.5 (least number which can give 32 when rounded to the nearest gram)
The highest value of the weight of actual packet = 32.4g (Highest number which can give 32 when rounded to the nearest gram)
Since a multipack contains 10 packets of crisp :
Least weight of multipack :
31.5 * 10 = 315g
Highest weight of multipack :
32.4 * 10 = 324g
solve for f.
2 + 1.25f = 10 - 2.75f
Answer:
2
Step-by-step explanation:
2 + 1.25f = 10 - 2.75f
1.25f + 2.75f = 10 - 2
4f = 8
f = 8/4
f = 2
