X-8 = 14
A.addition property of equality
B.subtraction property of equality
C.multiplication property of equality
D.division property of equality

Answers

It would be addition property of equality.

To solve for X, get it alone.
Get rid of -8 from the left hand side.
x-8=14
We add 8 to both sides
x - 8 + 8 = 14 + 8
x= 22
Therefore 8 is added to each side which makes it addition property!

Question 15 David went for a run in his town. He ran from his house to the school, which is 1.22 miles. Then he ran 3 laps around the school track. Each lap is 0.25 miles. Then he ran halfway to the gas station. The distance from the school track to the gas station is 2.68 miles. Finally he ran straight home, which is 0.49 miles. What is the total distance David ran?

Answers

Distance covered to travel house and school, d1 = 1.22 miles.

Distance covered in 3 laps, d2 = 3 × 0.25 = 0.75 miles.

Distance between halfway to the gas station from school,

d3 = 2.68÷2 = 1.34 miles.

Distance from his last position to home, d4 = 0.49 miles.

So, total distance covered is :

[tex]D = d1+d2+d3+d4\\\\D=(1.22+0.75+1.34+0.49)\ miles\\\\D=3.8\ miles[/tex]

Therefore, total distance covered is David is 3.8 miles.

Hence, this is the required solution.

The height, hh, of a plant (in inches) ww weeks since it was planted is represented by the equation h=1.2w+3h=1.2w+3. How many weeks ( round up to the nearest whole number) will it take the plant to reach one foot? ( Hint: convert feet to inches.) Answer value

Answers

Answer:

It will take 8 weeks for the plant to reach one foot.

Step-by-step explanation:

The equation is:

[tex] h = 1.2w + 3 [/tex]

Where:

h: is the height = 1 foot

w: is the time in weeks =?

We can convert feet to inches as follows:

[tex] 1 feet = 12 inches [/tex]

[tex] h = 1 ft*\frac{12 in}{1 ft} = 12 in [/tex]

Hence, the number of weeks is:

[tex] w = \frac{h - 3}{1.2} = \frac{12 - 3}{1.2} = 7.5 = 8 [/tex]

Therefore, it will take 8 weeks for the plant to reach one foot.

Determine the next three terms in the arithmetic sequence.

670,620,570
620,520,420
672,624,576
675,630,585

Answers

For any arithmetic sequence  aₙ₊₁ = aₙ + d

912, 864, 816, 768, 720

864 - 912 = -48 = d

so the next three terms:

720 + (-48) = 672

672 + (-48) = 624                    

624 + (-48) = 576

 

670, 620, 570   ⇒ 620 - 670 = -50 = d

so the next three terms:

570 + (-50) = 520

520 + (-50) = 470

470 + (-50) = 420

620, 520, 420   ⇒ 520 - 620 = -100 = d

so the next three terms:

420 + (-100) = 320

320 + (-100) = 220

220 + (-100) = 120

672, 624, 576   ⇒  624 - 672 = -48 = d

so the next three terms:

576 + (-48) = 528

528 + (-48) = 480                    

480 + (-48) = 432

675, 630, 585   ⇒  630 - 675 = -45 = d

so the next three terms:

585 + (-45) = 540

540 + (-45) = 495

495 + (-45) = 450
