Answer:

A)

Step-by-step explanation:

The correct expression which represents ''3 less than 5 times a number'' would be,

A) 5n - 3

Mathematical expression is defined as the collection of numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that,

A mathematical expression is,

''3 less than 5 times a number''

Let us assume that,

A number = x

Hence, the expression to represent ''3 less than 5 times a number'' is,

⇒ (5 × n) - 3

⇒ 5n - 3

So, the correct option is,

A) 5n - 3

Answer:

X = 15

Step-by-step explanation:

We move all terms to the left:

x+8+2x-(2x+13)=0

We add all the numbers together, and all the variables:

3x-(2x+13)+8=0

We get rid of parentheses:

3x-2x-13+8=0

We add all the numbers together, and all the variables:

x-5=0

We move all terms containing x to the left, all other terms to the right:

x=5

I'm not sure what you mean but I'll provide both.

5/8 + 3/4

11/8 or 1 3/8.

The common denominator of 5/8 and 3/4 is 8. 3/4 with a denominator of 8 would be 6/8.

5/8 + 6/8 = 11/8 or 1 3/8.

5/8 × 3/4

15/32.

Multiply the numerator by the numerator and the denominator by the denominator.

5 times 3 is 15 and 8 times 4 is 32.

So you get 15/32. This cannot be simplified.

Answer:

(r o g)(2) = 4

(q o r)(2) = 14

Step-by-step explanation:

Given

[tex]g(x) = x^2 + 5[/tex]

[tex]r(x) = \sqrt{x + 7}[/tex]

Solving (a): (r o q)(2)

In function:

(r o g)(x) = r(g(x))

So, first we calculate g(2)

[tex]g(x) = x^2 + 5[/tex]

[tex]g(2) = 2^2 + 5[/tex]

[tex]g(2) = 4 + 5[/tex]

[tex]g(2) = 9[/tex]

Next, we calculate r(g(2))

Substitute 9 for g(2)in r(g(2))

r(q(2)) = r(9)

This gives:

[tex]r(x) = \sqrt{x + 7}[/tex]

[tex]r(9) = \sqrt{9 +7{[/tex]

[tex]r(9) = \sqrt{16}[/tex]{

[tex]r(9) = 4[/tex]

Hence:

(r o g)(2) = 4

Solving (b): (q o r)(2)

So, first we calculate r(2)

[tex]r(x) = \sqrt{x + 7}[/tex]

[tex]r(2) = \sqrt{2 + 7}[/tex]

[tex]r(2) = \sqrt{9}[/tex]

[tex]r(2) = 3[/tex]

Next, we calculate g(r(2))

Substitute 3 for r(2)in g(r(2))

g(r(2)) = g(3)

[tex]g(x) = x^2 + 5[/tex]

[tex]g(3) = 3^2 + 5[/tex]

[tex]g(3) = 9 + 5[/tex]

[tex]g(3) = 14[/tex]

Hence:

(q o r)(2) = 14

Answer:

10.14

Step-by-step explanation:

1.69

x 6

------

10.14

The decimal points do not need to line up when multiplying..

1. The 6 on the bottom is multipled by the 9 on top which gets us 54 we write down the 4 and carry the 5.

2. The 6 on the bottom is now multiplied with the other 6 on top which gets us 36 plus the 5 that we carried earlier in the first step which equals 41. 36 + 5 = 41 We write down the 1 and carry the 4.

3. The 6 on the bottom is now multiplied with the 1 on top which gets us 6 plus the 4 that we carried ealier in the second step which equals 10. 6 + 4 = 10

4. So now we have the numbers 1014 but we can't forget about the decimal. Count all the numbers behind the decimal in the top and bottom numbers (if the bottom number doesn't have any numbers behind it, then no need to count), and we get two numbers behind the decimal.

5. When a number has no decimal in between the numbers then the decimal will always be at the end. So now we move the decimal (at the end) two times to the left and get 10.14

Check:

10.14 ÷ 6 = 1.69

True statement.

Answer:

-1/12

Step-by-step explanation:

The line passes through (0,10) and (-600,60)

So m = (60 - 10)/(-600 - 0) = 50/(-600) = -1/12

The slope-intercept equation of the given line is 3x + y = 25

Slope-intercept is one of the special forms of linear equations where we can find the slope-intercept of any point with its coordinates and its slope.

The line is passing through the point(x₁,y₁) = (7,4)

The slope of the line line(m) = -3

Slope-intercept equation

y-y₁ = m( x- x₁)

Where (x₁,y₁)  is (7,4) and Slope,m is -3

Let us substitute these values in the slope-intercept equation, It becomes

y - 4 = -3(x - 7)

y - 4 = -3x + 21

3x + y  = 21 + 4

3x + y = 25  

which is the slope-intercept equation of the points (7,4) and slope -3

(1) 2x + 3y = 31 y

(2) 2x + 3y = x + 7

(3) 31y = x + 7

(3) x = 31y - 7

(2) 2(31y - 7) + 3y = 31y - 7 + 7 ; 62y - 14 + 3y = 31y ; 34y = 14 ; y = 14/34 ; y = 7/17

(3) x = 31y - 7 ; x = 31*(7/17) - 7 ; x = (217 - 119)/17 = 98/17

x = 98/17 ≈ 5.76

y = 7/17 ≈ 0.41

Answer:

Variance: 26.5

Standard Deviation: 5.1478150704935

Step-by-step explanation:

First, Add up all of the numbers: 6 + 7 + 11 + 12 + 19 = 55

Square the total, and then divided the number of items in the data set55 x 55 = 3025

3025 / 5 = 605

Take your set of original numbers from step 1, squared them individually this time, and added them all up:(6 x 6) + (7 x 7) + (11 x 11) + (12 x 12) + (19 x 19) = 711

Subtract the amount in step 2 from the amount in step 3:711 - 605 = 106

Subtract 1 from the number of items in my data set:5 - 1 = 4

Divide the number in step 4 by the number in step 5:106 / 4 = 26.5

Finally, take the square root of the number from step 6 (the variance),

√(26.5) = 5.1478150704935

The wavelength measurement of the figure is,

⇒ 2 meter

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

We have to given that;

The figure is shown in image.

Since, We know that;

Wavelength is the distance between identical points in the adjacent cycles of a waveform signal propagated in space or along a wire.

Hence, We get;

The wavelength measurement of the figure is,

⇒ 3.5 - 0.5 meter

⇒ 2 meter

Thus, The wavelength measurement of the figure is,

⇒ 2 meter
