The distributive property also combines subtraction and multiplication for example, 3 x (5 — 2) = (3 x 5) —(3 x 2). Explain how you could use the Distributive Property and mental math to find 5 x 198.
After using distributive property we find the solution of 5 × 198 is 990.
What is Distributive property?
By the rule of distributive property, multiplying the sum of two or more addends by a number gives the same result as when each addend is multiplied individually by the number and the products are added together.
The expression is given as;
5 × 198
Now, By using distributive property we calculate as;
5 × 198 = 5 × ( 200 - 2 )
= (5 × 200) - (5 × 2)
= 1000 - 10
= 990
Hence, After using distributive property we find the solution of 5 × 198 is 990.

Use properties to rewrite the given equation. Which equations have the same solution as 2.3p – 10.1 = 6.5p – 4 – 0.01p? Select two options.
2.3p – 10.1 = 6.4p – 4
2.3p – 10.1 = 6.49p – 4
230p – 1010 = 650p – 400 – p
23p – 101 = 65p – 40 – p
2.3p – 14.1 = 6.4p – 4
The equivalent equation for the given equation is 2.3p - 10.1 =6.49p - 4. Therefore, option B is the correct answer.
Given that, 2.3p – 10.1 = 6.5p – 4 – 0.01p.
We need to find which equations have the same solution as the given equation.
What is an equivalent equation?Equivalent equations are algebraic equations that have identical solutions or roots. Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation. Multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation.
Now, 2.3p - 10.1 = 6.5p - 4 - 0.01p can be simplified as follows:
To add or subtract terms of algebraic equations group like terms add numerals and keep the variables the same.
That is, 2.3p - 10.1 = (6.5p - 0.01p) - 4
⇒2.3p - 10.1 =6.49p - 4
The equivalent equation for the given equation is 2.3p - 10.1 =6.49p - 4. Therefore, option B is the correct answer.

Find a counterexample to show that the conjecture is false.
The sum of two numbers is always greater than their difference.
The statement is false, a counterexample is given by using the numbers 1 and -1.
How to find the counterexample?Here we have the statement:
"The sum of two numbers is always greater than their difference"
So we just need to find two numbers such that the statement is false.
This is really trivial, for example, we can propose the numbers 0 and 0.
The sum gives 0 + 0 = 0
The difference is 0 - 0 = 0
The sum is not greater than the difference.
Now, I will propose a less trivial counterexample, let's use the numbers 1 and -1.
The sum gives 1 + (-1) = 1 - 1 = 0
The difference gives: 1 - (-1) = 1 + 1 = 2
The difference is larger than the sum, so we found a counterexample for the given statement.

Solve each system by elimination.
For the given systems of equations, we have that:
1) The infinite solutions have the following format: (3y - 12, y, 10y - 31).
2) There is one solution: (1.58, -3.45, 3.89).
3) There is one solution: (3, 2, 4).
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For item 1, the system is:
3x + y - z = -5.-4x + 2y + z = 17.-2x - 4y + z = -7.From the first equation, we have that:
z = 3x + y + 5.
Replacing on the second equation, we have that:
-4x + 2y + 3x + y + 5 = 17
-x + 3y = 12
x = 3y - 12.
Replacing on the third equation, we have that:
-2x - 4y + 3x + y + 5 = -7
x - 3y = -12
Since x = 3y - 12:
3y - 12 - 3y = -12
0 = 0.
Free variable, hence:
x = 3y - 12.y = y.z = 3x + y + 5 = 9y - 36 + y + 5 = 10y - 31.The infinite solutions have the following format: (3y - 12, y, 10y - 31).
For item 2, the system is:
x + 5y + 3z = -4.x + 2y - 3z = 8.-3x + 2y + 3z = -12.From the first equation:
x = -4 - 5y - 3z.
Replacing on the second equation:
-4 - 5y - 3z + 2y - 3z = 9.
-3y -6z = 13.
3y + 6z = 13.
Replacing on the third equation:
-3(-4 - 5y - 3z) + 2y + 3z = -12
12 + 15y + 9z + 2y + 3z = -12
17y + 12z = -14.
From the second equation, we have that:
z = (13 - 3y)/6.
Hence, replacing on the third again:
17y + 2(12 - 3y) = -14
11y + 24 = -14.
y = -3.45.
z = (13 - 3 x (-3.45))/6 = 3.89.
x = -4 - 5(-3.45) - 3(3.89) = 1.58.
Hence:
There is one solution: (1.58, -3.45, 3.89).
For item 3, the system is:
-4x - 2y + 5z = 4.5x + 2y - z = 15.5x - 2y - 3z = -1.From the second equation:
z = 5x + 2y - 15.
Replacing on the first:
-4x - 2y + 5(5x + 2y - 15) = 4
-4x - 2y + 25x + 10y - 75 = 4
21x + 8y = 79.
Replacing on the third:
5x - 2y - 3(5x + 2y - 15) = -1
5x - 2y - 15x - 6y + 45 = -1.
-10x - 8y = -46.
Adding both resulting equations, we have that:
11x = 33.
x = 3.
Then
21x + 8y = 79.
63 + 8y = 79
8y = 16
y = 2.
z = 5x + 2y - 15 = 5(3) + 2(2) - 15 = 4.
There is one solution: (3, 2, 4).
