If three times the sum of two, numbers is 42 and five times their difference is 20, find the numbers​

Answers

Answer 1

Answer:

x=9 and y=5

Explanation:

You can use the substitution method to eleminate x in the first equation with the value you will get from the second equation

Answer 2

Answer:

The two numbers are 5 and 9.

Explanation:

Given the information in the problem, if three times the sum of two numbers is 42, we can attempt to work backwards by doing the opposite of "three times the sum", which is dividing 42 by 3:

[tex]42/3=[/tex]

[tex]14[/tex]

We've figured out that the sum of these two numbers is 14.

Again, given the information in the problem, five times the difference of these two numbers is 20. Now, the only number that can multiply by 5 to get 20, is 4. We have to think of two numbers that will both, add up to 14, and when subtracted, have a difference of 4.

We can conclude that our two numbers are:

[tex]5[/tex] & [tex]9[/tex]

-

To check your work, run through the problem and simulate the given processes:

(First: Three times the sum of two numbers = 42)

[tex]5+9=14[/tex]

[tex]14*3=42[/tex]

(Second: Five times their difference is 20)

[tex]9-5=4[/tex]

[tex]4*5=20[/tex]

Therefore, our solution is correct!

1)The first one is if u are alcoholic,

3)glaucoma is about eyes(it's caused by abnormally high presure in your eyes)

4)nicotine makes the feeling of hunger disappear most of the time so u might get skinnier if u smoke all day and forget to eat

Tobacco use leads to heart damage, which eventually leads to cardiovascular disease.  

• Smoking leads to disability and disease and almost harms every organ of the body.  

Smoking results in cancer, stroke, heart disease, diabetes, lung diseases, and COPD or chronic obstructive pulmonary diseases, which comprise chronic bronchitis and emphysema.  

Smoking is one of the prime cause of CVD or cardiovascular disease. The chemicals in cigarette smoke makes the cells lining the blood vessels in the heart to become inflamed and swollen. This can narrow the blood vessels and can result in several cardiovascular diseases.  

Some of the CVDs resulting due to smoking are atherosclerosis, stroke, coronary heart disease, abdominal aortic aneurysm, and peripheral arterial disease.  

Thus, heart damage taking place because of tobacco use resulting in a cardiovascular disease shows the connection between the tobacco use and chronic disease.

Athletic tape costs $80 for 32 rolls. It takes 1/2 of a roll to tape an ankle. You estimate that 9 of your athletes will need their ankle taped for every game that season (10 games). What do you estimate the total cost to be to tape ankles for the full season?

Answers

Answer:

$112.50

Explanation:9

9 ankles/game x 10 games/season = 90 ankles/season90 ankles/season x 1/2 roll/ankle = 45 rolls needed/season$80/32 rolls = $2.50/roll$2.50/roll x 45 rolls/season = $112.50/season

The total cost to tape ankles for the full season is $225

Since Athletic tape costs $80 for 32 rolls. Hence:

Cost per roll = $80/32 rolls = $2.5 per roll

There are 9 athletes and it takes 1/2 of a roll to tape an ankle, hence:

Roll for 9 athletes = (1/2 roll per ankle) * 9 athletes * 2 ankles per athlete = 9 rolls

There are 10 games in a season, hence:

Total amount of rolls = 9 rolls * 10 games = 90 rolls

Total cost = $2.5 per roll * 90 rolls = $225

Therefore the total cost to tape ankles for the full season is $225

The blood that fell on the t-shirt absorbed due to the ____________ forces of the fabric being stronger than the force that keeps blood together. *

Answers

Answer: adhesive force of the fabric is stronger than the cohesive force of the blood

Explanation:

adhesive force of the shirt caused the blood to lose it shape or cohesion and absorb.

adhesive forces are use to refer to attractive forces acting on two different  substances, in this case blood and clothe. one is in a liquid form while the other is a solid form(cotton). the adhesive forces of the clothe is stronger so it pulls the blood making it loose it cohesive forces thereby staining the clothe.

Answer:

The answer is "Absorption"

Explanation:

Absorption properties of fabrics were examined tentatively using 216 different fabric tests of various development. It is demonstrated that around 26% to 40% of water is absorbed during the initial 10 seconds, contingent upon the fabric development; the level of water ingestion surpasses half in 30 seconds and arrives at 75% in 100 seconds. Yarn type is found to have the main impact on the dynamic water absorption properties of teny textures. 29.5 tex ring checked yarn has a quicker water retention than 29.5×2 tex ring checked yarn and 29.5×2 tex open end yarn, and 29.5×2 tex open end yarn has the least water absorption speed.

The impact of heap length, twist and weft thickness on the level of water retention stays restricted contrasted with that of yarn type, and no critical impact of these boundaries on water ingestion is found throughout the previous 100 seconds.
