The Average of 16 and x is 21
Find x?

Please answer quick!

Answers

Answer 1

Answer:

x = 26

Step-by-step explanation:

There are two numbers and average is the sum of a certain amount of numbers divided by the same amount.

21 × 2 = 42

42 - 16 = 26

x = 26

Answer 2

Answer:

x = 26

Step-by-step explanation:

Forming the equation,

→ (16 + x)/2 = 21

Now the value of x will be,

→ (16 + x)/2 = 21

→ 16 + x = 21 × 2

→ 16 + x = 42

→ x = 42 - 16

→ [ x = 26 ]

Hence, the value of x is 26.

0

This is because they are both the same opposite number, and you are adding.

But, if it was, [tex]\frac{64}{5}+\frac{64}{5}[/tex] then it would be [tex]25.6[/tex] or [tex]\frac{128}{5}[/tex].

So, the answer is 0.

Answers

Answer:

x ≤ 2

(when graphed, closed circle on two, shaded to the left)

Step-by-step explanation:

3/4 x - 2/3 ≤ 5/6

Add 2/3 to both sides:

3/4x ≤ 5/6 + 2/3

3/4x ≤ 3/2

Divide by 3/4 on both sides:

x ≤ 3/2 ÷ 3/4

Nike and Adidas are having a huge sale for the next 5 days. Create a graph to determine if the shirts and cost are proportional.

B) Write an equation to illustrate the relationship between the number of t-shirts and cost?

C) Using the equations predict the cost of 20 shirts sold.

D) 1%at docs the point (5, 35) represent in the context ofthc situation pertaining to Nike?

E) Which company has the better cost per shirt?​

Answers

Answer:

See the graph with both lines attached

A) From the tables we see the constant change of values in the second column and the initial value is zero.

This represents a proportional relationship.

B) Rate of change is 7 per shirt, the equation is:

y = 7x, where y is cost, x - is the number of shirts

C) When x = 20,

y = 7*20 = 140Cost of 20 shirts is $140

D) The point (5, 35) represents that:

The cost of 5 shirts is $35

E) The second table has confusing titles (not about the number or cost of shirts) but if we assume its same as the first table, then Adidas has greater price of $8 per shirt.

Comparing the prices, Nike has better cost

price of $8 per shirt.

Answers

Answer:

Step-by-step explanation:

18/14 and 10/15 don't have the same value. Only equivalent fractions have same value.

These two are not equivalent fractions

Answer:

No.

Step-by-step explanation:

Without much calculation, we can notice that 18/14 is actually greater than 10/15 since its numerator is greater than its denominator, making it greater than 1. However, 10/15 is less than 18/14 since its numerator is less than its denominator making it less than 1. In short:

18/14 > 1

10/15 < 1

18/14 > 10/15

10. Solve for all values of x algebraically (find the zeroes):
3x^2 +12x – 7 = x^2+ 3x – 2

Answers

Answer:

x = -5 or 1/2

Step-by-step explanation:

From the question,

3x²+12x-7 = x²+3x-2

Collect like terms

3x²-x²+12x-3x-7+2 = 0

2x²+9x-5 = 0

Using factorization method to solve the quadratic equation

2x²+10x-x-5 = 0

(2x²+10x)-(x+5) = 0

2x(x+5)-1(x+5) = 0

(x+5)(2x-1) = 0

Either,

x+5 = 0

x = -5

or,

2x-1 = 0

2x = 1

x = 1/2.

Therefore,

x = -5 or 1/2

Nella travelled 1/3 of a journey by bus, 2/3 of the remainder by bicycle and the remaining 9 km on foot. a)How far did Nella cycle? b)What was the total distance that Nella travelled?​

Answers

Answer:

18km

40.5km

Step-by-step explanation:

Let b = journey by bus

c = journey by bicycle

d = total journey

c = (2/3 x d) x 2/3

divide both sides by 2/s

c(3/2) = (2/3)d

c + 9km = 2/3d

c + 9km = 3/2 c

collect like terms and solve for c

3/2c - c = 9km

1/2c = 9km

c = 18km

2. IF cycling (18km) and walking (9km) make up 2/3 of the journey, 2/3 of the journey is 27km

2/3d = 27km

divide both sides by 3/2 to find d

d = 40.50 km

[ Read Story ------> " Tribal Nations: Climate Change Threatens Traditional Ways of Life ") Of the 2.5 million American Indians and Alaska Natives registered in the U.S. Census, approximately 1.1 million live on or near reservations or native lands, located mostly in the Northwest, Southwest, Great Plains. and Alaska, although indigenous communities can be found throughout the U.S. Climate change poses particular threats to indigenous culture, well-being, and ways of life in every region of the United states. Chronic stresses such as extreme poverty are being exacerbated by climate change impacts: these impacts include reduced access to traditional foods, decreased water quality, and increasing exposure to health and safety hazards. In Alaska, Maine, the Pacific Northwest, and other coastal locations, erosion and inundation related to climate change are so severe that some communities are already relocating from historical homelands to which their traditions and cultural identities are tied. Climate change impacts Tribal Nations' access to Traditional foods. Fare such as salmon, shellfish, crops, and marine mammals have provided sustenance as well as cultural, economic, medicinal and community health for countless generations. Some plants used for medicines and food are becoming increasingly difficult to find, or are no longer found in historical ranges. Subsequentshifts from Traditional lifestyles and diet -----compounded by persistent poverty, food insecurity, the cost of non-traditional foods, and poor housing conditions---have led to increasing health problems in native communities. Climate change is likely to amplify other indirect effects to traditional foods and resources, including limited access to gathering places, hunting grounds, and environmental portion. A key uncertainty is how indigenous people will adapt to climate change, given their reliance on local, wild foods and the geographic isolation of some communities. For example , increased wildfire frequency and intensity due to fuel loading brought on by drought and other factors may affect tribal homes, safety, economy, culturally important species, medicinal plants, traditional foods, and cultural sites. Additionally, tribes have varying levels of preparedness and some have a limited ability to cope with extreme events. Climate change also affects the integrity and stability of the ecosystems on which indigenous peoples depend by altering ecosystems processes and biodiversity. Ecosystems provide a rich array of benefits and services including habitat for fish and wildlife, drinking water storage and filtration, fertile soils for growing crops, buffering against a range of stressor, and aesthetic and cultural values. Changes in these resources have social, cultural. and economic effects on native communities in part. Events such as droughts, floods, wildfires, and pest outbreaks associated with climate change ( for example, bark beetles in the West and Alaska) are already disrupting ecosystems. In the longer term, there is increasing risk of species extinction, which could be particularly devastating to native communities reliant on specific for food, medince, and ceremonies. Decreases in water quality and quanity are effecting Native Americans' drinking water supplies, food, cultures, ceremonies, and traditional way of life. Native communities ' vulnerabilities and lack of capacity to adapt to climate change are exacerbated by historical and contemporary federal and state land- use policies and practices, political marginalization, legal issues associated with tribal water rights, water infrastructure deficiencies, and poor socioeconomic conditions.
