Answer:

The answer is 3 1/2.

Step-by-step explanation:

-There are 2 simple ways to do this.

-The first is just subtracting 3/4 and 1/4 which equals 2/4 or 1/2.

-The second way is to turn it into an improper fraction.

-(5*4)+3=23 and (2*4)+1=9.

-23/4-9/4=14/4

-14/4=3 1/2

Answer:

3 1/4

Step-by-step explanation:

5 3/4 - 2 1/4

First subtract the whole numbers of the two mixed fractions, so:

= 5 - 2

= 3

Now, combine the leftover fractions:

= 3/4 - 1/4

= 2/4

= 1/4

Lastly, put the whole number and fraction together:

= 3 1/4

Find the accumulated value of an investment of 12,000 at 8 % compounded semiannually for 11 years
AleksAgata [21]
The "compound amount" formula is A = P(1+r/n)^(nt),
where P=original investment, r=interest rate as a decimal fraction; n=number of compounding periods, and t=number of years.

Then A = $12000 * (1+0.08/2)^(2*11) 
             = $12000(1.04)^(22)  =  $28,439.03  (answer)

Suzie made a mistake in the following problem. The mistake was made in Line ___. Only input the number of the first incorrect li
zalisa [80]

Answer:

Mistake in Line 2

Step-by-step explanation:

Line 1  

7(6) ÷ 5 + 42  

Line 2  

7(6) ÷ 5 + 16  

Line 3  

42 ÷ 5 + 16  

Line 4  

42 ÷ 21  

Line 5  

2

To simplify any expression we use order of operation

Line 1 is 7(6) ÷ 5 + 42  

Order of operation is PEMDAS

First we start with parenthesis

so we multiply 7(6) in line 2

7*6- 42

So Line 2 is 42 ÷ 5 + 42  

Hence there is a mistake in Line 2

Which graph shows the solution to this system of inequalities?<br><br> y&lt;-1/3x+1<br> y&lt;_2x-3
kari74 [83]

The graph that shows the solution to the system of inequalities is: C (see the image attached below).

<h3>How to Determine the Graph of the Solution to a System of Inequalities?</h3>

Given the following systems of inequalities:

y < -1/3x + 1

y ≤ 2x - 3

Below are the features of the graph that represents a solution to the system of inequalities:

  • The boundary line of y < -1/3x + 1 would be a dashed line and the shaded area would be below it, because of the inequality sign, "<".
  • The boundary lines of y ≤ 2x - 3 would be a solid line and the shaded area would be below it, because of the inequality sign, "≤".
  • The slope of the shaded line that represents  y < -1/3x + 1, would be -1/3, and the line would be a decreasing line which intersects the y-axis at 1.
  • The slope of the line that represents y ≤ 2x - 3, would be 2, and the line would also be an increasing line that intersects the y-axis at -3.

Therefore, the graph that shows the solution to the system of inequalities is: C (see the image attached below).
