Write an equation based on the word problem below and solve it. *
You have $150 in your savings
account. You earn money to
walk your neighbor's dog every
day after school. If it takes you
8 weeks to have $246 in your
account, how much money, m,
do you earn per week?
m = $13 per week
m = $12 per week
Om = $11 per week
O m = $10 per week
Answer:
m = $12 per week
Step-by-step explanation:
The equation would be 8m + $150 = $246. To find out how much money you earn a week, you need to solve for m.
First, subtract $150 from both sides of the equation. Doing so will leave you with an equation of 8m = $96.
Next, divide both sides by 8. This will leave you with m = $12, which is your final answer of how much money you earn a week.

Which expression is equivalent to 25 x 1/5?
Answer:
The answer would be E.
When you solve 25 x 1/5, you get 5.
When you solve 25 ÷ 5, you get 5.
The equivalent expression is 25 ÷ 5.
Option E is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example.
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
25 x 1/5
= 25 x 1/5
= 5 x 5 x 1/5
= 5
Now,
1/25 x 5
= 1/5
1/25 x 1/5
= 1/125
1/25 ÷ 1/5
= 1/25 x 5
= 1/5
5 ÷ 25
= 5/25
= 1/5
25 ÷ 5
= 5
We see that,
25 x 1/5 and 25 ÷ 5 have the same value.
Thus,
The equivalent expression is 25 ÷ 5.

-3/2+3/7 The denominator needs to be the same
Answer:
Step-by-step explanation:
To make the denominator same, find Lease common denominator of 2 and 7
LCD of 2 and 7 = 2*7 = 14
[tex]\frac{-3}{2}+\frac{3}{7}=\frac{-3*7}{2*7}+\frac{3*2}{7*2}\\\\\\=\frac{-21}{14}+\frac{6}{14}\\\\\\=\frac{-21+6}{14}\\\\\\=\frac{-15}{14}\\\\\\=-1\frac{1}{14}[/tex]
Answer:
-15/14
Step-by-step explanation:
Find the Least Common Denominator (LCD) for the two fractions, so the operation can be performed. The LCD is constructed from the factors the fractions have, making sure that all factors they need are included.
In our case, for the first fraction, the factor 2 is needed, and for the second fraction, the factor 7 is needed. Then the LCD is: 2 * 7 = 14
So now, let's write both denominators with the same LCD, by finding the appropriate equivalent fractions:
- 3 /2 = - (3*7) / (2*7) = -21 / 14
3 / 7 = (3*2) / (7*2) = 6 / 14
Therefore the combining can now be performed and renders:
- (21/ 14) + (6/ 14) = - (15/14)
The result is then the fraction : -15/14

How many liters each of a 30% acid solution and a 50 % acid solution must be used to produce 70 liters of a 40 % acid solution? (Round to two decimal places if
necessary.)
Answer:
30%: 35 liters
50%: 35 liters
Step-by-step explanation:
The desired concentration is halfway between the concentrations of available solutions, so the mixture will be equal amounts of each.
35 liters of 30% acid and 35 liters of 50% acid must be used
_____
If you want to write an equation, it usually works well to let the variable represent the amount of the most concentrated constituent: 50% acid. Then the amount of acid in the final mix is ...

Find the Slope using the Slope Formula
Answer:
Slope = -1
Step-by-step explanation:
Given coordinates,
→ x1 = -2
→ y1 = 1
→ x2 = -3
→ y2 = 2
Now we have to,
→ Find the slope using slope formula.
Formula we use,
→ Slope (m) = (y2 - y1)/(x2 - x1)
Let's find the required slope,
→ m = (y2 - y1)/(x2 - x1)
→ m = (2 - 1)/(-3 - (-2))
→ m = (2 - 1)/(-3 + 2)
→ m = 1/(-1)
→ [ m = -1 ]
Hence, the value of slope is -1.

Find the coordinates of Rif Q(-1, 3) is the midpoint of PR and P has
coordinates of (5, 6)
Answer:
R(-7,0)Step-by-step explanation:
Let the midpoint of PR be Q(-1,3) where P is (5,6). To get the other coordinate R, we will use the midpoint formula as shown;
Q(X,Y) = {(x₁+x₂)/2, (y₁+y₂)/2}
From the formula;
X = (x₁+x₂)/2 and Y = (y₁+y₂)/2
From the coordinates given, X = -1, Y = 3, x₁ = 5 and y₁ = 6. To get x₂ and y₂, we will substitute the given points into the expressions above;
To get x₂;
X = (x₁+x₂)/2
-1 = (5+x₂)/2
cross multiply
-1*2 = 5+x₂
-2 = 5+x₂
subtract 5 from both sides
-2-5 = 5+x₂-5
x₂ = -7
Similarly to get y₂
Y = (y₁+y₂)/2
3 = (6+y₂)/2
cross multiply
3*2 = 6+y₂
6 = 6+y₂
subtract 6 from both sides
6-6 = 6+y₂-6
y₂ = 0
Hence the coordinate of R(x₂, y₂) is (-7,0)

If Beyoncé performed as many songs as
Robyn per capita, how many would you
expect Beyoncé to sing?
Answer:
20 songs
Step-by-step explanation:
Robyn sang a total of 13 songs for a population of 62000 people, the per capita is the ratio of the total songs sang to the total number of people. Hence:
Robyn per capita = songs performed / population = 13 / 62000
Beyonce sang to a population of 91000 people, given that Beyonce and Robyn had the same per capita, therefore:
Beyonce per capita = songs performed / population
13/62000 = songs performed / 91000
songs performed = 13/62000 × 91000 = 19.08
songs performed ≈ 20 songs
Beyonce is expected to sing about 20 songs
Answer:
Around 20
