1 = 8 / 8 + 8 - 8
2 = 8 / 8 + 8 / 8
3 = (8 + 8 + 8)/8
4 = 8 * 8 / (8 + 8)
5 = √(8 + 8) + 8 / 8
6 = 8 - (8 + 8) / 8
7 = (8 * 8 - 8) / 8
8 = 8 - (8 - 8) / 8
9 = (8 * 8 + 8) / 8
10 = 8 + (8 + 8) / 8

How do you solve 4 equation with 4 unknows?
Create a matrix of the coefficients of each equation. The solutions to the equations should make up the rightmost column of the matrix. Then, row reduce the matrix until you are able to rewrite the equations and solve them. The matrix should be a 4x5 matrix (4 rows and 5 columns) for four equations with four variables. This is known as a system of equations.
How many combinations can you make using numbers 1 through to 10 each with three different numbers?
1000
A system of numbers in which each number is shown using only the digits 0 and 1?
binary.
When you formulate a system of equations you have at least fact(s) that each need to be summarized as one sentence and then their corresponding equations.?
Two (2)
How do you create equations for the numbers 1-10 using 4s for each with out the square root?
1 = 4/4 2 = (4 + 4)/4 3 = (4 + 4 + 4)/4 4 = 4 5 = 4 + 4/4 6 = 4 + (4 + 4)/4 7 = 4 + (4 + 4 + 4)/4 8 = 4 + 4 9 = 4 + 4 + 4/4 10 = 4 + 4 + (4 + 4)/4
Is an array of numbers where each row contains the numbers from one of the equations?
matrix
An array of numbers where each row contains the numbers from one of the equations?

What are balanced equations?
Equations in which the total numbers of each kind of atom with the same number of protons in its nuclei are present on the left and right sides of the equations.
How can you find the pH of phosphoric acid that is complelely ionized using the 3 equations?
Use the Ka values for each and do three ICE tables and carrying the numbers through.
What are equivalent equations How do you find them Write a few sentences describing them?
Sample Response: Equivalent equations have the same solution. You can create equivalent equations by performing the same operations on each side of the equation. You can check for equivalence by finding the solution for each equation.
What does it mean for a coordinate pair to be a solution to a system of equations?
It means that if you replace one variable with one of the numbers, and the other variable with the other numbers, and then evaluate the expressions on each side of the equations, the equalities will be true.
Does the law of conservavation of mass forces equations to have equal numbers of atoms?
Yes, and even more than that: equal numbers of each kindof atoms.
How do you solve systems of equations using linear combination?
You select the linear combination of the equations in such a way that at each stage you eliminate one variable.You select the linear combination of the equations in such a way that at each stage you eliminate one variable.You select the linear combination of the equations in such a way that at each stage you eliminate one variable.You select the linear combination of the equations in such a way that at each stage you eliminate one variable.
Why do chemical equations have to be balanced?
As no chemical equations create or destroy new molecules, both sides need to be balanced to show the same amount of each element is on either side of the equation.
Select a significant year like the year in which you were born or a historical year like 1776 The create the numbers 1 through 50 using each of the digits in that year exactly once?

What characteristics do balanced equations have?
They simply have the same numbers of atoms each element on one side of the equation as the other side.
Balanced chemical equations show the proportions of reactants and products nesecary fro what to be conserved?
Mass and numbers of each kind of atoms present.
