Answer:

The sales tax rate is 5%.

Step-by-step explanation:

To determine the sales tax rate if you already know the amount of tax being added to the purchase price, divide the amount of tax by the purchase price. In this example, divide $1.29 (amount of tax being added) by $25.79 (purchase price). When you do that, you will see that the answer is 0.0500, or 5%.

What is the converse of the following conditional statement? If x = –10, then x2 = 100

tangare [24]

The converse would be If x² = 100 then x = -10

So essentially if the conditional statement is p → q then the converse is q → p (In essence, the converse of a conditional statement is formed by interchanging the hypothesis and the conclusion.)

Answer:

p = 7/2

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Left to Right

Equality Properties

Multiplication Property of Equality
Division Property of Equality
Addition Property of Equality
Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

-4p + 9 = -5

Step 2: Solve for p

Subtract 9 on both sides: -4p = -14
Divide -4 on both sides: p = 7/2

Step 3: Check

Plug in p into the original equation to verify it's a solution.

Substitute in p: -4(7/2) + 9 = -5
Multiply: -14 + 9 = -5
Add: -5 = -5

Here we see that -5 does indeed equal -5.

∴ p = 7/2 is the solution to the equation.
