brian has $45.25 saved and earns $7.25/week. Dakota has $25.25 saved and earns $9.75/week. In how many weeks will they have the same amount?

Explanation pleaseeeeeeee
ASAPPPPPPPPPP!!!!!!!!!!!!!!

Answers

STEP ONE:
Set up the equation
45.25 + 7.25x = 25.25 + 9.75x
STEP TWO:
Subtract 7.25x from both sides
45.25 = 25.25 + 2.5x
STEP THREE:
Subtract 25.25 from both sides
20 = 2.5x
(Flip equation)
2.5x = 20
STEP FOUR:
Divide 2.5 from both sides
x = 8

Since x represents weeks, it will take 8 weeks for Brian and Dakota to have the same amount of money.

Hope this helped!

They will have same money after 10 weeks.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Brian has $45.25 saved and earns $7.25/week. Dakota has $25.25 saved and earns $9.75/week.

Let the number of weeks be x.

Now, money earned by Brain x weeks is 45.25+7.25x

Money earned by Dakota x weeks is

25.25+9.75x

Now, 45.25+7.25x=25.25+9.75x

2x=20

x=10

Therefore, they will have same money after 10 weeks.

Answer: A) y = 7x - 22

Explanation: First of all, we know it cannot be D, because if the answer was D, the slope would have to be 14. Next, to find the value of b (the y intercept) we have to do 7(3) and we will then get 21. We then must subtract 21 from -1 and get the slope of -22. The reason we subtract is because we must make the x value 0, and since it is 3, we go backwards. Hope this helped!

Answers

Answer:

k≤2

Step-by-step explanation:

18≥5k+4k

Step 1: Simplify both sides of the inequality.

18≥9k

Step 2: Flip the equation.

9k≤18

Step 3: Divide both sides by 9.

9k

/9≤18/9

k≤2

The solution to the inequality 18≥5K+4K is K ≤ 2.

To solve the inequality 18 ≥ 5K + 4K, we can combine the like terms on the right-hand side and simplify:

18 ≥ 5K + 4K

Combining the like terms:

18 ≥ 9K

We want to isolate the variable K on one side of the inequality.

Divide both sides of the inequality by 9:

(18/9) ≥ (9K/9)

2 ≥ K

Therefore, the solution to the inequality is K ≤ 2.

rewrite 1/2 x 1/2 as an exponential expression with a base of 2

Answers

Answer:

2^-2

Step-by-step explanation:

According to the properties of integer exponents, 1/a^n = a^-n.

So 1/2 x 1/2 = 1/2^2 = 2^-2.

1/2 x 1/2 can be rewritten as the exponential expression 2^-2.

Edmentum answer

The expression 1/2 × 1/2 can be written as 2⁻² in the exponential form with the base 2.

What are Expressions?

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Given expression is 1/2 × 1/2.

We have to write the expression in an exponential form with the base 2.

1/2 × 1/2 = (1/2)²

             = 1 / 2²

We have the rule for exponentiation 1 / aᵇ = a⁻ᵇ

1/2 × 1/2 = 2⁻²

Hence the exponential form of the given expression with the base 2 is 2⁻².

If you let y = length of the foot and x = length of the forearm, this equation can be simplified to
y = 0.860x + 3.302.

Read the speech and answer the question.Voluntourism: An Opportunity Too Good to be TrueA Speech to the Student Body of Evergreen High[1] Picture this: It's Spring Break, and you fly off to some country where there's lush rainforests and beautiful, blue coastlines to explore. There's also people in need, so you decide to blend your vacation with volunteering. Volunteering as a tourist, or voluntourism, seems like a great way to explore new regions and help people at the same time. However, this "volunteer plus travel" experience can actually harm local communities. While many teens might view traveling and volunteering abroad as a worthwhile adventure, there are more genuine and effective ways to make a difference.[2] Most would agree that volunteering in general is a worthy use of time. However, what if you found out the children you are "helping" are actually being kept in poor conditions so voluntourists will spend money to come to the local area? Dale Rolfe, a supporter of ethical voluntourism, explains the shocking reality that "Animal sanctuaries and orphanages are often manufactured for the voluntourist...encouraging a cycle of exploiting the very animals and children the volunteers are trying to help."[3] Proponents of the "volunteer plus travel" experience also argue that traveling to new places builds character and is a valuable way to learn about different cultures. With voluntourism, however, participants often pursue experiences that are all about them. For example, they sign up to build a school for a gold star on their resume, but they have no real building skills and take jobs away from local construction workers (Schulten). Or, they arrive to teach English but instead take selfies with the locals. One world traveler and ethical voluntourist believes voluntourism "can perpetuate small minded views of the world by taking insulated, fake, and structured experiences and selling them as unabridged and eye opening" (Carlos). The voluntour experience is a mirage. The voluntourist's eyes are not opened to real life at the destination, and lasting change is not achieved.[4] If you want a genuine experience where you can see a lasting impact, there are better options than voluntourism. You can volunteer in your local community. Give an hour every week to your town's animal rescue. Serve monthly dinners to the homeless. Be a reliable, positive influence on a child who needs a mentor. Studies show that volunteering and forming lasting relationships with those you help has a positive impact on your physical and emotional health. In fact, blood pressure is reduced, memory is improved, and rates of depression are reduced (Michaels).[5] There is another reason to look into alternatives to voluntourism. Did you know the average "voluntour" travel package costs $3,400 (Rolfe)? Could that travel money be better spent? If the world's citizens are your passion, it could go to an international organization. If you care about education, your funds can be used to buy books for students in faraway lands. If you want villagers to have clean water, contribute funds to local efforts to dig wells. If you want to experience a different culture, travel to the country as a guest, and learn from the locals how you can best help them after you've returned home. But do not voluntour.[6] In reality, there are better ways to make a difference. Voluntourism might appear to be an adventure that blends travel and helping others, but it does little except provide a costly, superficial experience that might actually do more harm than good. So, volunteer where you are most needed-at home, where you can stay to see the job through and form genuine, lasting relationships. Choose a beautiful coastline closer to home and send the travel money you saved to an international organization that will put it to good use. Whatever you do, don't turn someone else's hardship into your vacation.How does the speaker's metaphor of the mirage in paragraph 4 support the purpose of the speech? It develops the idea that voluntour opportunities are not what they appear to be. It emphasizes the idea that voluntour work is difficult and draining but worth the effort. It reveals the significant contribution that voluntours make to the areas they visit. It shows that voluntourism experiences can even take place anywhere-even in the desert.
