what is the product of -2 1/4 and -4 1/2 as a mixed number and in simplest form

Answer:

120:300 is in the same ratio as 2:5. Can you add the pound sign? My keyboard does not have it.

Step-by-step explanation:

Add the two parts of the ratio together

2 + 5 = 7

Find 5:7

5:7 = x:420  

5/7 = x/420              Cross multiply

7x = 5 * 420             Combine the right

7x = 2100                  Divide by 7

x = 2100/7

x = 300                      

Find the second number

420 - 300 = 120

120 : 300 is the answer

Divide top and bottom by 60

120/60 = 2

300 / 60 = 5

Answer: 18≤n≤38 is absolute value inequality for the problem.

Step-by-step explanation:

Given situation:- Half of a number n is at most 5 units from 14

that means the difference between 14 and half times n is less than 5

[tex]\Rightarrow |14-\frac{1}{2} \times n|\leq 5\\\Rightarrow|2( 14-\frac{1}{2} \times n)|\leq2(5)\\\Rightarrow|2(14)-2(\frac{1}{2} \times n)|\leq2(5)\ \text{(Multiplying 5 on the both sides)}\\\Rightarrow|\ 28-n|\leq10\\\Rightarrow\ 28-n\leq10\ or\ -(28-n)\leq10\\\Rightarrow\ n=28-10=18\ or\ n=28+10=38\\(i.e.)\ 18\leq\ n\leq \ 38[/tex]

⇒18≤n≤38 is absolute value inequality for the problem.

A. -14x+21

because -7 times 2x is -14x and -7 times -3 is 21

For this case we have:

We locate the given points on the negative axis of the x coordinate

We shadow the region between both points

The shaded region will be the difference or distance between both numbers.

Algebraically, the difference is given by:

[tex]| -13 - (- 4) | = | -9 | = 9\\[/tex]

Answer:

[tex]Distance = 9\\[/tex]

See attached image

The distance between -13 and -4 on a number line is the absolute value of their difference, which is 9 units.

The distance between two points on a number line is the absolute difference between those points. In this case, the points are -13 and -4. To calculate the distance, we subtract these values in such a way that we get a positive result.

So, we subtract -4 from -13, which is the same as adding 4 to 13, i.e.,: -13 - (-4) = -13 + 4 = -9.

However, distance cannot be negative, so we take the absolute value of -9, which is 9. Therefore, the distance between -13 and -4 on the number line is 9 units. None of the options provided seem to correctly represent this result.

1. The attendance at the Cleveland arena was 20,311 people.

2. The largest arena can seat 1,800 more people than the smallest arena.

3. The estimated seating capacity difference between the Atlanta and Los Angeles arenas is 1,300.

4. The total attendance for the sold-out games is 37,124 people.

5. The combined capacity of the Cleveland and Boston arenas is 6,186 people greater than the biggest college basketball arena.

1. **Last night's game in Cleveland:**

  The attendance at the Cleveland arena last night was 20,562 - 251 = 20,311 people. This is because the arena was 251 seats short of being filled to its full capacity.

2. **Difference in seating capacities:**

  The difference in seating capacities between the largest (Los Angeles) and smallest (New Orleans) arenas is calculated by subtracting the smaller capacity from the larger one: 20,300 - 18,500 = 1,800. Therefore, the largest arena can accommodate 1,800 more people than the smallest arena.

3. **Estimate of seating capacity difference (Atlanta and Los Angeles):**

  The estimated difference in seating capacities between the Atlanta and Los Angeles arenas can be obtained by rounding the capacities to the nearest hundred, making the calculation easier. The rounded capacities are 20,300 and 19,000, resulting in an estimated difference of 1,300.

4. **Attendance at sold-out games:**

  The total attendance for the sold-out games in Boston and New Orleans is the sum of their individual capacities: 18,624 + 18,500 = 37,124 people.

5. **Combined capacity of Cleveland and Boston vs. biggest college arena:**

  The combined capacity of the Cleveland and Boston arenas is 20,562 + 18,624 = 39,186 people. Since this is greater than the capacity of the biggest college basketball arena (33,000), the combined capacity of the Cleveland and Boston arenas is 6,186 people greater.

In summary, the attendance at the Cleveland arena last night was 20,311 people. The largest arena can seat 1,800 more people than the smallest arena. The estimated seating capacity difference between the Atlanta and Los Angeles arenas is 1,300. The total attendance for the sold-out games in Boston and New Orleans is 37,124 people. The combined capacity of the Cleveland and Boston arenas is 6,186 people greater than the biggest college basketball arena.

Hey there!!

Given :

Sum of two integers = -5 and the product is -36.

Hence,

... x + y = -5

... xy = -36

x + y = -5

... y = -x - 5

xy = -36

...x ( -x - 5 ) = -36

... -x² - 5x = -36

... x² + 5x - 36 = 0

This can't be factored so solve using quadratic equation

x = [-b ±√(b2-4ac)]/2a      a=1, b=5, c = -36

x = [-5±√(52-4(-36))]/2

x = [-5 ±√169]/2

x = (-5 ± 13)/2

x = (-5+13)/2= 8/2 = 4  OR

x = (-5-13)/2 = -18/2 = -9

x = 4, -9

Note here that since x+y=-5

For x=4, y=-9

for x = -9, y = 4

The two numbers are 4, -9

Hope my answer helps!!

The two integers are 4 and -9.

To find the two integers, let's assume that one integer is x and the other integer is y. Since the sum of the two integers is -5, we can write the equation x + y = -5. Similarly, the product of the two integers is -36, so we can write the equation xy = -36.

Now, we can solve these equations simultaneously to find the values of x and y.

From the first equation, we can express x in terms of y as x = -5 - y. Substituting this value into the second equation, we get (-5 - y)y = -36.

Simplifying this equation gives us y^2 + 5y - 36 = 0. Factoring or using the quadratic formula, we find that y = -9 and y = 4.

Substituting these values back into the equation x = -5 - y, we find that x = 4 and x = -9.

Therefore, the two integers are 4 and -9.

Isolate the x. Note the equal sign. What you do to one side, you do to the other.

First, subtract 2 from both sides

2 (-2) - x = (5/8) - 2

-x = 5/8 - 2

Make sure they have the same denominator. Remember that what you multiply to the denominator, you multiply the numerator:

-x = 5/8 - 16/8

-x  = - 11/8

Isolate the x. Divide -1 from both sides

(-x)/-1 = (-11/8)/-1

x = 11/8

11/8 is your answer for x

m = (-10 + 25)/(-1 + 4) = 15/3 = 5

so

5 = (20 + 10)/(n + 1)

5(n+1) = 30

5n + 5 = 30

5n = 25

n = 5

Answer

n = 5

Answer:

value of n is 5

Third option is correct.

Step-by-step explanation:

Let the equation of the linear function is y = mx + b

From the given table, we have two points (-4,-25) and (-1,-10)

The slope of the line containing these two points is

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{-10+25}{-1+4}\\\\m=\frac{15}{3}\\\\m=5[/tex]

Now, put m = 5, x = -4 and y = -25 in the equation y = mx+b

[tex]-25=5\cdot(-4)+b\\\\-25=-20+b\\\\b = -5[/tex]

Therefore, equation of linear function is [tex]y=5x-5[/tex]

Now, put x = n and y =20

[tex]20=5n-5\\\\5n=25\\\\n=5[/tex]

Therefore, the value of n is 5

The smallest would be 14 and then 15 and then 16.

Use the equation 2n=12+n+2. solve for n. Since it's consecutive, the equation would be n+n+1+n+2

Luigi is 15 years old.

we determine that Luigi is 15 years old.

The question involves solving for Luigi's age based on the given relationship between Mario and Luigi's ages. We are told that Mario's age is three times the difference between Luigi's age and the number 9, and that Mario is currently 18 years old. We need to create an equation and solve for Luigi's age.

Let's let L represent Luigi's age. The problem statement tells us:

Mario's age = 3 * (L - 9)

Given that Mario's age is 18, we substitute this value into the equation:

18 = 3 * (L - 9)

To find L, we start by dividing both sides of the equation by 3:

6 = L - 9

Then, we add 9 to both sides to solve for L:

15 = L

Therefore, Luigi is 15 years old.

Slope intercept form: y = mx + b

So

-2x + y = 9

Add 2x to both sides

-2x + y + 2x = 9 + 2x

Simplifying

y = 2x + 9
