Delila is multiplying three negative numbers and determines that the solution will be negative . Is she correct or incorrect? Justify your thinking.
Answer: Delila is correct about this determination.
Step-by-step explanation: The rule for multiplying two negatives is that a negative and a negative always equal a positive. Therefore, multiplying two negatives will give a positive. However, we still have to multiply that positive by another negative to get our answer. Another multiplication rule states a negative and a positive always equals a negative. Let's set up an example with the numbers -7, -8, and -4:
Using the first multiplication rule mentioned above, let's multiply:
-8 x -7 = 56
Using the second multiplication rule mentioned above, we can finish the equation and get our answer:
56 x (-4) = -224
-7 x -8 x -4 = -224.
Final answer: Delila is correct. Multiplying three negatives will result in a negative solution.
Keitaro walks at a pace of 3 miles per hour and runs at a pace of 6 miles per hour. Each month, he wants to complete at least 36 miles but not more than 90 miles. The system of inequalities represents the number of hours he can walk, w, and the number of hours he can run, r, to reach his goal.
3w + 6r ≥ 36
3w + 6r ≤ 90
A graph shows w on the x-axis, from 0 to 30, and t on the y-axis, from 0 to 24. Two solid lines are shown. The first line has a negative slope and goes through (0, 6) and (12, 0). Everything above and to the right of the line is shaded. The second line has a negative slope and goes through (0, 15) and (30, 0). Everything to the left of the line is shaded.
Which combination of hours can Keitaro walk and run in a month to reach his goal?
2 hours walking; 12 hours running
4 hours walking; 3 hours running
9 hours walking; 12 hours running
12 hours walking; 10 hours running
The combination of hours that Keitaro can walk and run in a month to reach his goal will be A. 2 hours walking; 12 hours running
How to illustrate the information?From the information, Keitaro walks at a pace of 3 miles per hour and runs at a pace of 6 miles per hour. Each month, he wants to complete at least 36 miles but not more than 90 miles.

help please :))
Answer:
V = 1 (Please mark the answer as brainliest)
Step-by-step explanation:
8(5 - 6v) = -7 - v
40 - 48v = -7 - v
40 = -7 + 47v
47 = 47v
1 = v
Answer:
v = 1
Step-by-step explanation:
Let's solve the problem,
→ 8(5 - 6v) = -7 - v
→ 40 - 48v = -7 - v
→ 40 + 7 = -v + 48v
→ 47v = 47
→ v = 47/47
→ [ v = 1 ]
Hence, the value of v is 1.

What is Euclidean geometry?Euclidean geometry is the study of geometrical shapes (plane and solid) and figures based on different axioms and theorems.
Now since Spherical geometry is the geometry of the two-dimensional surface of a sphere. In this context the word "sphere" refers only to the 2-dimensional surface and other terms like "ball" or "solid sphere" are used for the surface together with its 3-dimensional interior.
Euclidean geometry differs from spherical geometry because Euclidean Geometry are known to make use of a plane to be able to set points and lines, but Spherical Geometry are known to make use of spheres to set up points and great circles.
Thus, Euclidean geometry differs from spherical geometry because Euclidean geometry is used to set points by the use of plane.

Christy buys 3 1/4 pounds of pork roast and 5 1/2 pounds of beef roast. She pays a total of $67.50. The pork costs $0.50 per pound less than the beef. What is the combined cost of one pound of pork and one pound of beef?
The combined cost of one pound of pork and one pound of beef is $ 15.5.
How to estimate the combine cost of two articles bought in a butchery
The total cost is equal to the sum of the products of unit price and quantity of an article. In this problem we find the sum of the quantities of two products (pork roast, beef roast), whose expression can be described below:
67.50 = (3.25) · (x - 0.50) + (5.5) · x
Where x is the unit cost of the beef roast.
Now we proceed to solve the equation for x:
67.50 = 3.25 · x - 1.625 + 5.5 · x
69.125 = 8.75 · x
x = 7.9
A pound of beef roast costs $ 7.9 and a pound of pork roast costs $ 7.4. Then, the combined cost of one pound of prok and one pound of beef is:
C = 1 · 7.9 + 1 · 7.4
C = 15.5
The combined cost of one pound of pork and one pound of beef is $ 15.5.

By first figuring out the value of a single unit and then multiplying the number by that value, the unitary approach in mathematics can be used to determine the required value.
• The unitary technique can be used to determine how many kilometres can be covered with 2 litres of gasoline, for instance, if a car goes 80 km on 6 l of fuel.
He washed 4 dishes in 2 minutes, thus we need to calculate how long it would take Rick to wash 6 plates. 4 plates, according to the rule, equals 2 minutes. Applying the unitary approach 1 plate in 2/4 of a minute 1 plate Equals 12 minute. 3 minutes equals 6 plates (12 times 6.6 plates).

The average income,I, in dollars, of a lawyer with an age of x years is modeled with the following function:
Solving a quadratic equation, the youngest age for which the average income of the lawyer is of $250,000 is of 26 years.
What is a quadratic function?A quadratic function is given according to the following rule:
y = ax² + bx + c
[tex]\Delta = b^2 - 4ac[/tex]
The solutions are:
[tex]x_1 = \frac{-b + \sqrt{\Delta}}{2a}[/tex]
[tex]x_2 = \frac{-b - \sqrt{\Delta}}{2a}[/tex]
In which:
[tex]\Delta = b^2 - 4ac[/tex]
For this problem, the equation that models the income as function of age is given by:
I(x) = -425x² + 45500x - 650000.
The income is of 250,000 when I(x) = 250000, hence:
250000 = -425x² + 45500x - 650000.
425x² - 45500x + 900000 = 0.
Hence the coefficients are a = 425, b = -45500 and c = 900000, then:
[tex]\Delta = (-45500)^2 - 4(425)(900000) = 540250000[/tex][tex]x_1 = \frac{45500 + \sqrt{540250000}}{2(425)} = 80.87[/tex][tex]x_2 = \frac{45500 - \sqrt{540250000}}{2(425)} = 26.18[/tex]The youngest age for which the average income of the lawyer is of $250,000 is of 26 years.

Answer:
The equation for the number of people is 25.50x + 6.25 = 235.75 and the number of people who can go to the amusement park are 9.
Step-by-step explanation:
We have,
Spend on parking and admission = $235.75
Spend on parking = $6.25
Cost of ticket per person = $25.50
Let number of number of people = x
Now,
According to the question;
25.50x + 6.25 = 235.75
So, this the equation for number of number of people.
Now,
25.50x + 6.25 = 235.75
25.50x = 229.50
x = 9
So, number of number of people is 9, which we find out using the above mentioned equation.
Hence, we can say that the equation for the number of people is 25.50x + 6.25 = 235.75 and the number of people who can go to the amusement park are 9.
The number of people who can go to the amusement park is 9 they have $235.75 to spend on parking and admission. Parking is $6.25.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Let x be the number of people
6.25 + 25.50x = 235.75
25.50x = 235.75 - 6.25
25.50x = 229.5
x = 9
