The additive inverse, or opposite, of a number is the value you add to it to get zero. You find it by changing the sign of the number. So the additive inverse of 5 is -5, and the additive inverse of -3 is 3.
Explanation:In mathematics, the additive inverse of a number is what you add to a given number to get zero. This is often known as the 'opposite' or 'negation' of a number. The additive inverse of a number 'a' is denoted as '-a'.
For example, the additive inverse of 5 is -5, because 5 + (-5) = 0. Similarly, the additive inverse of -3 is 3, because -3 + 3 = 0.
To find the additive inverse of a number, you essentially change the sign of the number. If the number is positive, its additive inverse will be negative. If the number is negative, its additive inverse will be positive.

Calculate the mass of a 5.50 cm3 cylinder of a substance that has a density of 4.20 g/cm3.
Final answer:
The mass of the 5.50 cm³ cylinder of a substance with a density of 4.20 g/cm³ is 23.10 g.
Explanation:
To calculate the mass of the cylinder, you can use the formula: Mass = Density x Volume.
Given that the density of the substance is 4.20 g/cm³ and the volume of the cylinder is 5.50 cm³, you can substitute these values into the formula to find the mass.
Mass = 4.20 g/cm³ x 5.50 cm³ = 23.10 g.
The mass of the cylinder with a volume of 5.50 cm³ and a density of 4.20 g/cm³ is calculated using the formula Mass = Density × Volume, which results in a mass of 23.1 grams.
Explanation:To calculate the mass of a cylinder of a substance when the volume and density are known, use the formula:
Mass = Density × Volume
Given that the density of the substance is 4.20 g/cm³ and the volume of the cylinder is 5.50 cm³, we can substitute these values into the formula:
Mass = 4.20 g/cm³ × 5.50 cm³
Mass = 23.1 g
The mass of the substance is 23.1 grams. It's important to note that the result should be reported with the appropriate number of significant figures. The original volume was given to three significant figures, so the final answer should also reflect three significant figures.

What is expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. A finite combination of symbols that are well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression.
Given:
The expressions are equivalent,
Expressions that function identically despite having distinct appearances are called equivalent expressions. If two algebraic expressions are equivalent, then when we enter the same value(s) for the variable, the two expressions have the same value (s).
As you can see in the options 2 - x because this will equal (-x +2) or 2 + (-x)
Thus, the expression which is not equivalent is 2 - x.

you want to buy a bouquet of yellow roses and baby's breath for $16.the baby's breath costs $3.50 per bunch,and the roses cost $2.50 each.you want one bunch of baby's breath and some roses for your bouquet.how many roses can you buy?
After subtracting the cost of one bunch of baby's breath ($3.50) from the total budget ($16), you have $12.50 left for the roses. Since each rose costs $2.50, you can buy 5 roses to complete your bouquet within the budget.
To calculate the number of roses that can be bought, first, we need to subtract the cost of one bunch of baby's breath from the total budget for the bouquet. The cost of one bunch of baby's breath is $3.50. With a total budget of $16, we subtract the cost of baby's breath to see how much is left for the roses:
$16.00 - $3.50 = $12.50
Since each rose costs $2.50, we will divide the remaining budget by the cost of each rose to find out the number of roses that can be purchased:
$12.50 / $2.50 = 5 roses
Therefore, you can buy 5 roses along with one bunch of baby's breath to make up your $16 bouquet.

12 bars of soap for $10.00 or 5 bars of soap for $4.00
To determine which package is a better deal, we need to compare the price per bar of soap for each package. The second package is the better deal as it has a lower price per bar of soap.
Explanation:The question is asking about the comparison of two different packages of soap based on their price and quantity. To determine which package is a better deal, we need to calculate the price per bar of soap for each package.
For the first package, we have 12 bars of soap for $10.00. To find the price per bar, we divide the total cost by the number of bars: $10.00 ÷ 12 = $0.83 per bar.
For the second package, we have 5 bars of soap for $4.00. Again, we divide the total cost by the number of bars: $4.00 ÷ 5 = $0.80 per bar.
Comparing the prices per bar, we can see that the second package is cheaper, so it is the better deal.

2x + y = 5
3y = 15 – 6x
A(6, –7)
B(2, 1)
C(–2, –9)
D(–4, 13)
Answer: The system of equations have many solutions and the correct options are A,B and D.
Explanation:
The given equations are,
[tex]2x+y=5[/tex] ..... (1)
[tex]3y=15-6x[/tex] .... (2)
Simplify the second equation.
[tex]3y+6x=15[/tex]
[tex]3(y+2x)=15[/tex]
Divide both sides by 3.
[tex]2x+y=5[/tex]
It is same as equation (1). Since equation (1) and (2) are same, therefore all the points lies on the line or which satisfies the equation are the solution of the given system of equations.
Test the points whether the point lies on the line or not.
Check for point A(6,-7).
[tex]2(6)+(-7)=5[/tex]
[tex]5=5[/tex]
LHS and RHS are equal, therefore the point A is the solution of the system of equations.
Check for point B(2,1).
[tex]2(2)+(1)=5[/tex]
[tex]5=5[/tex]
LHS and RHS are equal, therefore the point B is the solution of the system of equations.
Check for point C(-2,-9).
[tex]2(-2)+(-9)=5[/tex]
[tex]-13=5[/tex]
LHS and RHS are not equal, therefore the point C is not the solution of the system of equations.
Check for point D(-4,13).
[tex]2(-4)+(13)=5[/tex]
[tex]5=5[/tex]
LHS and RHS are equal, therefore the point D is the solution of the system of equations.
Therefore the options A,B and D are correct.
The points (6, –7), (2, 1), and (–4, 13) satisfies the equation and hence, will be the solution of the equation. The correct solution for this system is A, B, and D.
Given:
The given system of linear equations is,
[tex]2x + y = 5\\3y = 15 - 6x[/tex]
Equate the y coefficient of the equations and write them as,
[tex]6x + 3y = 15\\6x+3y = 15[/tex]
The given system of equation is the same equation and hence, will have infinite solutions.
Now, the solution of equation from the given options can be found by putting each point in the equation and checking for its satisfaction of the equation.
So, try All the points given. Point A(6,-7) Where x=6, y=-7
Put in equation.
[tex]-7+2(6)=5\\-7+12=5\\5=5[/tex]
Hence LHS=RHS
Point B(2,1), Where x=2, y=1
Put in equation.
[tex]1+2(2)=5\\1+4=5\\5= 5[/tex]
Hence, LHS= RHS
Point C(-2,-9), Where x=-2, y=-9
Put in equation.
[tex]-9+2(-2)=5\\-9-4=5\\-13\neq 5[/tex]
Hence LHS[tex]\neq[/tex]RHS
Point D(-4,13)
Where x=-4, y=13

[tex]13+2(-4)=5\\13-8=5\\5=5[/tex]
Hence, LHS= RHS
Therefore, points (6, –7), (2, 1), and (–4, 13) satisfies the equation and hence. will be the solution of the equation.
