The cost of one pound beef is $3.2

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Cost 4.5 pound of beef = $14.40

So, the unit rate for beef

= 14.40 / 4.5

= $3.2

Hence, the cost of one pound beef is $3.2

As the compounding frequency increases, the yield increases as well. But there's a limit to that increase.

Consider depositing $100 into an account at 5% interest. Let's consider a timespan of 1 year. These values were picked arbitrarily.

Using the formula A = P(1+r/n)^(nt), we can find the various yield amounts when n varies

The table below shows how A changes based on the values of n. I've let P = 100, r = 0.05 and t = 1.

As n gets larger, the value of A slowly approaches 105.13 when you round to the nearest penny.

So eventually the investment yield hits a ceiling of some sort.  We cannot make the investment grow forever in some fixed amount of time (in this case 1 year).

Answer:

a=18

Step-by-step explanation:

The value of a or m is 18 in the linear equation, y = 5x - 2.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

The table represents a linear function.

The data is given in the attached image.

The general equation of the linear function is,

y = ax+b.

Where a is the slope and b is constant.

By using the first and the third points from the table to find the equation of the linear function,

When x = 3  and y = 13,

13 = 3a+b      {equation 1}

When x = 5 and y = 23

23 = 5a+b      {equation 2}

Solving the system of equation,

we get,  

a = 5  and b = -2

So, the equation is,

y = 5x - 2

Now, x = 4

Then y = m = 20 - 2 = 18

Therefore, the value of m is 18.

Answer: 2n-3>=-20

Step-by-step explanation: instead of the equal sign put a line under the sign <

After translating the given statement, the inequality will be 2x - 3 ≥ -20.

Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare the two values.

Less than (or less than and equal to), larger than (or greater or equal to), or not similar to signs are used in place of the equal sign in between.

As per the information in the question,

The statement for the inequality in the question,

Twice, the difference between a number and 3 is at least -20.

Let the number be x.

Twice the number is 2x.

So,

2x - 3 ≥ -20

Answer and Step-by-step explanation:

3 x 2 - x = ? Well, if you simplify it's just 5x. But, if you are trying to solve this then you have to know what x is or what your answer is. But, if you're trying to solve 3 x 2 = x then x would equal 6. Of course, if you know the answer or what x equals then plug it in as such, let's say x = 2 then you would plug 2 in for x and solve, 3 x 2 = 6 - 2 = 4. But, if you are trying to solve for x then look at the answer, let's say it is 24 so, 3 x 2 - x = 24, x would equal -18.

Answer:

Step-by-step explanation:

Given the equation solved by Morgan, Dakota and Taylor expressed as 7x+5x+1=73, to get the value of x, the valid steps are as shown;

7x+5x+1=73

take the sum of 7x and 5x

12x+ 1 = 73

subtract 1 from both sides

12x+1-1 = 73-1

12x = 72

Divide both sides by 12

12x/12 = 72/12

x = 6

Based on the calculation above, the students with invalid first step is Dakota.

Dakota added 5x with 1 to get 6x which is an invalid step because 1 is not attached to a variable x. A function cannot be added to a constant hence making his first step invalid.

Answer:

As you can see, Taylor failed to add 1 to her equation. This ruins the whole first step. She also used 72 instead of 73 for the answer. Taylor is incorrect.
