Answer:
The identity property of addition
Step-by-step explanation:
Jamal uses the steps below to solve the equation 6x – 4 = 8.
Step 1: 6x – 4 + 4 = 8 + 4( Addition step of equality)
Step 2: 6x + 0 = 12
Step 3: 6x = 12 (Identity property of Addition)
Step 4: StartFraction 6 x Over 6 EndFraction = StartFraction 12 Over 6 EndFraction
Step 5: 1x = 2
Step 6: x = 2
The that property justifies Step 3 of his work is known as the identity property of addition.
The identity property of addition can be defined as when a given number x is added to zero, the result is we obtained x which is the given number itself.

Team Z can do the work in 26 days, and working together Team Z and Y can do the same work in 14 days. How many days would it take for Y alone to do the work? Round your answer to the nearest whole number.
Answer:
30 days
Step-by-step explanation:
The above question is solved as shown below:
Working together Team Z and Y can do the same work in 14 days.
1/Team Y + 1/Team Z = 1/14 days
Team Z can do the work in 26 days,
Hence:
1/Team Y + 1/26 days = 1 /14 days
= 1/ Team Y + 1/26 = 1/14
1/Team Y = 1/14 - 1/26
The Lowest Common Denominator = 182
Hence:
1/Team Y = 13 - 7/182
1/Team Y = 6/182
Cross Multiply
Team Y × 6 = 1 × 182
Team Y = 182/6
Team Y = 30.33 days
Approximately to the nearest whole number = 30 days
Therefore, Team Y alone can do the job in 30 days

The Outdoor Furniture Center buys wooden benches for $50 each. The owner of the Outdoor Furniture Center sells the benches for a 120% markup. At the end of the season, the owner wants to sells all the benches that are in stock. He sells the benches for 20% off.
What is the total price of a bench with the 20% discount plus a 5% sales tax?
Practice
Show your work
Answer:
92.4
Step-by-step explanation:
50$ + 120% = 110
110 - 20% = 88
88 + 5% = 92.4
The total price of a bench with the 20% discount plus a 5% sales tax is $92.4.
What is Markup Percentage?Markup percentage is defined as the total profit of the commodity in terms of percentage. It is calculated by dividing the difference of the selling price and the cost with the cost and then multiply to 100.
Markup Percentage = [(sales price - cost) / cost] × 100
Cost of a bench = $50
There is 120% markup in the bench
Selling price = $50 + ($50 × 120%)
= $50 + ($50 × 1.2)
= $50 + $60
= $110
At the end of the season, owner gives 20% discount.
Price of the bench after 20% discount = $110 - (20% × 110)
= $110 - (0.2 × 110)
= $110 - $22
= $88
There is a sales tax of 5%.
Last selling price of the bench = $88 + (5% × $88)
= $88 + (0.05 × $88)
= $88 + $4.4
= $92.4
Hence, the owner sells the bench at the season at $92.4.

4. Which of the following differences could not give a distance between two points on a number line? Explain why. a. 19-7 c. -12-(-7) b. -3 - (-18) d. 14-(-6)
-12 -(-7) could not be a distance.
Distance:
Distance traveled is the total length of the path traveled between two positions. It can either be a 0 or a positive number that's mean it can never be a negative number.
So from the above-given statement we have
a) 19-7 = 12 (which is positive number)
b) -12 - (-7) = -12 + 7 = -5 ( which is a negative number)
c) -3-(-18) = -3 + 18 = 15 ( which is a positive number)
d) 14-(-6) = 14 + 6 = 20 ( which is a positive number)
Therefore option b i.e., -12 - (-7) cannot be a distance between two points on a number line.

2 4/5 divided by 2 1/5 plz answer corectly ps this is mixed number ones
Answer:
The correct answer is 1.27.
Step-by-step explanation:
Step 1: Turn the mixed numbers into improper fractions.
2 4/5 = 14/5
2 1/5 = 11/5
Step 2: Turn the improper fractions into decimals.
14/5 = 2.8
11/5 = 2.2
Step 3: Divide the fractions.
2.8 ÷ 2.2 = 1.27 when rounded to the nearest hundred.

Step-by-step explanation:
18/44=9/22
THIS IS AMSWER
Answer:
18/44 simplified is 9/22.
Step-by-step explanation:
Since both of these numbers can be divided evenly by 2, then we can divide them by 2.
18 ÷ 2 = 9
44 ÷ 2 = 22
Since 9 and 22 don't have any like factors, the simplified fraction is 9/22.

What is m∠2 + m∠3? Explain. Two lines and two line segments. Lines A B and C D are parallel horizontal lines with point C directly below point A and point D directly below point D. A vertical segment extends from A to C. A diagonal segment extends from C to B. Angle B A C is labeled 1. Angle A C B is labeled 3. Angle B C D is labeled 4. Angle A B C is labeled 2. A. 180; m∠1 + 90 = 180, so m∠2 + m∠3 = 180. B. 180; m∠1 + 90 = m∠2 + m∠3, so m∠2 + m∠3 = 180. C. 90; m∠1 + m∠2 + m∠3 = 180. m∠1 = 90, so m∠2 + m∠3 = 90. D. 90; ∠2 and ∠3 are corresponding angles, so m∠2 + m∠3 = 90.
The line AB and the segments AC and BC form triangle ∆ABC, which gives the measure of m‹2 + m‹3 as following option;
C. 90°; m‹1 + m‹2 + m‹3 = 180°. m‹1 = 90°, so m‹2 + m‹3 = 90°
How can m‹2 + m‹3 in ∆ABC be calculated?From the given descriptions, we have;
Lines AB and CD are horizontal lines.
Segment that extends from A to C which is segment AC is a vertical line
Therefore;
m‹BAC = m‹1 = 90°
‹BAC, ‹ABC, and ‹ACB, which are angles 1, 2, and 3 are interior angles of ∆ABC
Which gives;
m‹1 + m‹2 + m‹3 = 180° (sum of interior angles of a triangle theorem)
Therefore;
90° + m‹2 + m‹3 = 180° (substitution property)
m‹2 + m‹3 = 180° - 90° = 90°
m‹2 + m‹3 = 90°
The correct option is therefore;
C. 90°; m‹1 + m‹2 + m‹3 = 180°. m‹1 = 90°, so m‹2 + m‹3 = 90°Learn more about the interior (and exterior) angles of a triangle here:

The value of 3centimeters to kilometers is 0,00003 km
Converting centimeters to metersIn order to convert centimeters to kilometers, we will use the conversion factor below.
100cm = 1m
1000m = 1km
Given 3cm
3cm = 3/100 m
3cm = 0.03m
Convert to km
Since 1000m = 1km
0.03m = 0.03/1000
0.03m = 0.00003km
