how do you add and subtract integers?​

Answer:

Below

Step-by-step explanation:

Follow this rule:

● if the numbers multiplied together have the same signs, the product is a positive number.

● if the nupbers multiplied togethers have different signs, the product is a negative number.

Answer:

Step-by-step explanation:

anytime you multiply a positive+Positive= it equals a positive number  if you multiplying a negative + positive it will equal a negative even if the positive number is bigger for example 4 x -9= -36           9 x 4= 36      -9 x -4 = 36

Answer:

112x-280

Step-by-step explanation:

Answer:

a=m-n

(Add n to both sides)

a+n=m-n+n

(The -n and +n cancel out, on the right side of the equation)

a+n=m

(Now subtract a from both sides)

a+n-a=m+a

(The +a and -a cancel out, on the right side of the equation)

n=m+a

Answer:

[tex]\huge \boxed{n=-a+m}[/tex]

Step-by-step explanation:

[tex]a=m-n[/tex]

Adding [tex]n[/tex] to both sides.

[tex]a+n=m-n+n[/tex]

[tex]a+n=m[/tex]

Subtracting [tex]a[/tex] from both sides.

[tex]a+n-a=m-a[/tex]

[tex]n=m-a[/tex]

Answer:

Linear equation formed by equating both functions is used to find the x-coordinate of the intersection point.

Step-by-step explanation:

If we have two linear functions f(x) and g(x) which are intersecting at a point (a,b), then equating both functions we get a linear equation as

[tex]f(x)=g(x)=y[/tex]

On solving this linear equation we get the x-coordinate of the point of intersection, i.e., x=a.

After that, we need to substitute x=a in either f(x) or g(x) to get the y-coordinate of the point of intersection.

Therefore, the linear equation formed by equating both functions is used to find the x-coordinate of the intersection point.

Answer:

The expression simplified

Answer:

-4n^2 + -15n

Step-by-step explanation:

-3n(-n + 4) - n(3 + 7n)

= -3n * -n + -3n * 4 + -n * 3 + -n * 7n

= 3n^2 + -12n + -3n + -7n^2

= -4n^2 + -15n

Answer:

The correct option is Segment Addition Postulate

Step-by-step explanation:

The segment addition postulate states that where there are two points on a line A and C and a third point B can only be located on the line segment AB if and only if the the distances between point A and point B as well as the distance between point B and point C satisfy the equation AB + BC = AC

Therefore, given that in the figure,  the point B is in between point A and point C on segment AC then AB + BC

Similarly, AD = AE + ED.

Answer:

18

Step-by-step explanation:

6+6+3+3=18

Please Brainliest!!!

Answer:

No

Step-by-step explanation:

So lets do the first expression first

2(3x-6)

6x-6

So the first one is 6x-6

Now the second expression

2(3x)x-6

As you can see here, there's an extra x in this problem compared to the last problem, but lets still work it out

6x*x-6

So they are different.

If the extra x wasn't there then it would've worked.

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{13 \: \: units \: }}}}}[/tex]

Step-by-step explanation:

Perpendicular ( p ) = 5

Base ( b ) = 12

Hypotenuse ( h ) = ?

Finding the length of missing side

Using Pythagoras theorem

[tex] \boxed{ \sf{ {h}^{2} = { p}^{2} + {b}^{2} }}[/tex]

plug the values

⇒[tex] \sf{ {h}^{2} = {5}^{2} + {12}^{2} }[/tex]

Evaluate the power

⇒[tex] \sf{ {h}^{2} = 25 + 144}[/tex]

Add the numbers : 25 and 144

⇒[tex] \sf{ {h}^{2} = 169}[/tex]

Squaring on both sides

⇒[tex] \sf{ \sqrt{ {h}^{2} } = \sqrt{169}} [/tex]

Calculate

⇒[tex] \sf{ {h} = 13 \: units}[/tex]

Hope I helped!

Best regards! :D

Step-by-step explanation:

Remember: the midsegment is always parallel to the third side, and the length is half of the third side. (Third side = XY) Assuming that line segment XY is the length of the third side of the triangle, we can insert it into this equation:

[tex]m=\frac{AB}{2}[/tex]

Let's plug in XY for AB.

[tex]m = \frac{XY}{2}[/tex]

[tex]m=\frac{12}{2} \\[/tex]

[tex]AC=6[/tex]

Our final answer: AC = 6

Answer/Step-by-step explanation:

The following inequalities can be translated and matched as follows:

1. A number is larger than 5:

Let that number be x. Numbers that are larger than 5 are 6, 7, 8 and so on. Therefore, the number that is larger is greater than 5. This can be represented in the symbolic form as:

x > 5

2. A number is below 5:

Numbers that are below 5 are 4, 3, 2 and so on. Therefore, we can say the number, x, is less than 5. This can be written in symbolic form as:

x < 5

3. A number is not less than 5:

A number that is not less than 5 could equal 5 or any other number that is larger than 5. Therefore, we can say the number, x, equals 5 or greater than 5. This can be written as:

x ≥ 5

4. A number is at most 5:

At most 5, means the number, x, is either 5 or less than 5. This can be written as:

x ≤ 5

Answer:

The cup is a cooking measure of volume, commonly associated with cooking and serving sizes. It is traditionally equal to half a liquid pint in US customary units, or an amount between 200 mL and 250 mL (​1 ⁄ 5 and ​1 ⁄ 4 of a litre) in the metric system, which may vary due to location.

Answer:

x=(5/2,-3)

Step-by-step explanation:

2x²+x=15

2x²+x-15=0

(2x-5)(x+3)=0

x=(5/2,-3)

Answer:

the farmer has 242 apples left

Step-by-step explanation:

A = awnser

M= Monday

T= Tuesday

M= 242

T= 109

W = amount sold or 109

(M+T)-W= total amount left

use order of operations and add whats in the (   )

( 242+109 ) = 351 or ( M+T )

then you would use the sum of ( M+T ) and subtract W or 109 wich would then equal 242 so the equation

( 242+109 ) - 109 would equal 242 or ( M+T ) - W = A

Answer:

21

Step-by-step explanation:

12/4.+18

The lcm is 4.

12+4(18) all divided by 4

12+72=84

84/4=21

Answer:

[tex] \frac{84}{4} \: or \: 21[/tex]

Step-by-step explanation:

[tex] \frac{12}{4} + 18 = \frac{12}{4} + \frac{18}{1} = \frac{12 + 72}{4} = \frac{84}{4} \: or \: 21 [/tex]

Answer:

b=0       would appreciate brainliest

Step-by-step explanation:

Otherwise, no solution for this equation. You cannot isolate the variable a; its solution value can be anything, but you still find b=0.

2a+b=2a

b+2a=2a

b+2a-2a=2a-2a

b+0=0

b=0

1.   Which becomes 2(1) + 0 = 2(1)

2.    2 + 0 = 2 :

3.    2 = 2. Here we can observe the equality.

Answer:

1/ ( 4c+5)

Step-by-step explanation:

To be a multiplicative inverse, they multiply to 1

Let x be the multiplicative inverse

(4c+5) * x = 1

Divide each side by (4c+5)

x = 1/ ( 4c+5)

Answer:

Step-by-step explanation:

Given that:

Ken's prediction temperature for April 7C.

His prediction for May is 2C higher than April.

He attempts to use the number line to solve the problem.

On a number line, we have the origin at a given point zero, the positive x-axis to the right side, and the negative x-axis to the left side.

So, if Ken's starts from zero and move right to seven and the move units to the left, the error he made was moving 2 units to the left because he supposed to have continued in the right direction by moving 2 units forward. This is because moving to the left side will showing a decrease in the temperature by -2° C and he intends to have 2° C.

Answer: pemdas you solve each portion in the order of pemdas  parenthesis, exponents, multiplication, division, addition, and subtraction  so you would start with 2(5x)  than you would need to make both sides true so if you were to take 6 away from the left side of the equal sign you would need to do the same on the other side so put negative six on the right side
