Answers

Answer:

Step-by-step explanation:

Opposite numbers are the same distance from 0 on the number line, but in opposite directions. Steps I would follow:

first, check the directions to make sure they are opposite,

then read the digits, or count the tick marks or compare lengths with dividers or ruler or marks on a piece of paper to see if the distances are the same.

Answers

Answer:

a. 6Pack of paint brushes for $12.99

b. 5 classes for $64.99

c. 12 pack of paper plates

Step-by-step explanation:

I could buy a 6 pack of paint brushes for $ 12.99

buy 6 individual brushes for the price of $ 2.19 each.

6 x $2.19 = $13.14

first option is cheaper

10 classes for s total of $150

$150 ÷ 10 = $15 (price per class)

5 classes for $64.99

$64.99 ÷ 5 = $12.998 (price per class)

12 pack of paper plates for $2.29

25 pack for $4.99

$2.29 ÷ 12 = $0.1908 (price of one plate)

$4.99 ÷ 25 = $0.1996 (price for one plate)

6x + 13 = 37 what is X?

Provide reasoning

Answers

X=4

Explanation:

6x+13=37

Subtract 13 from both sides

6x=24

Then divide 6 by both sides

X=4

Answer:

x = 4

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define equation

6x + 13 = 37

Step 2: Solve for x

Subtract 13 on both sides: 6x = 24Divide 6 on both sides: x = 4

Step 3: Check

Plug in x to verify it's a solution.

Substitute: 6(4) + 13 = 37Multiply: 24 + 13 = 37Add: 37 = 37

Here we see that 37 does indeed equal 37.

∴ x = 4 is a solution of the equation.
