Answer:

3(6-x)

Step-by-step explanation:

The expression "Triple the difference of six less than a number" can be represented as 3 * (x - 6), where x represents the number.

To mathematically represent "Triple the difference of six less than a number," we can use the following expression:

3 * (x - 6)

Here, x represents the number, and the expression calculates the difference between the number and six, which is then multiplied by three.

Answer:

c = 3 is the only thing i can think of lmk if im wrong..

Step-by-step explanation:

c =3 because 12÷4 (pentagons)= 3

By rounding to 1 significant figure 542.04 × 1.88 equal to 1019.0352

is 1019.

We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.

To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.

Given we have to round off 542.04×1.88 = 1019.0352.

Now rounding off to one significant digit means we should have only one digit after the decimal place and the second digit after the decimal place is 3 which is less than 5.

∴ 1019.0352 rounded off to one significant digit is 1019.

Answer:

[tex]Boxes= 198[/tex]

Step-by-step explanation:

This question has uncleared details towards the end. However, one can deduce that we need to calculate the amount of box the available space can contain.

We have the following given parameters.

Shipping Container

[tex]Dimension: 2ft\ by\ 3ft\ by\ 33ft[/tex]

The box

[tex]Dimension: 1ft\ by\ 1ft\ by\ 1ft[/tex]

First, we calculate the volume of the shipping container.

[tex]V_A = 2ft * 3ft * 33ft[/tex]

[tex]V_A = 198ft^3[/tex]

Next, we calculate the volume of the box.

[tex]V_B = 1ft * 1ft * 1ft[/tex]

[tex]V_B = 1ft^3[/tex]

The number of box is then calculated as:

[tex]Boxes= \frac{V_A}{V_B}[/tex]

[tex]Boxes= \frac{198ft^3}{1ft^3}[/tex]

[tex]Boxes= \frac{198}{1}[/tex]

[tex]Boxes= 198[/tex]

Hence:

198 boxes will occupy the empty space

Answer:

The value of c that will result in a perfect square trinomial is (3)^2 or 9

The perfect square trinomial is: [tex](w+3)^2=139[/tex]

Step-by-step explanation:

We need to determine the value  of c that will result in a perfect square trinomial.

[tex]w^2+6w+ c =130+c[/tex]

Perfect square trinomial are of form: [tex]a^2+2ab+b^2=(a+b)^2[/tex]

Now, the equation given is:

[tex]w^2+6w+ c =130+c[/tex]

Looking at the term 6w, we can write it as 2(w)(3)

We are given: a = w, 2ab = 2(w)(3) so, b will be: (3)^2

So, we will be adding (3)^2 on both sides

[tex]w^2+6w+ c=130+c\\w^2+2(w)(3)+ (3)^2 =130+(3)^2\\The\:left\:side\:becomes: a^2+2ab+b^2\\We\:can\:write\:it\:as: (a+b)^2\\We\:have\:a=w\: and\: b=3\\(w+3)^2=130+9\\(w+3)^2=139[/tex]

So, The value of c that will result in a perfect square trinomial is (3)^2 or 9

The perfect square trinomial is: [tex](w+3)^2=139[/tex]

Answer:

[tex]R' = (-1,-0.5)[/tex]

Step-by-step explanation:

See attachment for complete question.

From the attachment:

[tex]P = (-3,-3)[/tex]

[tex]R = (1,2)[/tex]

Dilation:

[tex]D_{(0.5,P)}[/tex]

Required

Determine R'

First, subtract the coordinates of P from R. This means that R is measured from P.

[tex]R = (1-(-3),2-(-3))[/tex]

[tex]R = (1+3,2+3)[/tex]

[tex]R = (4,5)[/tex]

Next, apply dilation factor 0.5

[tex]R' = R * 0.5[/tex]

[tex]R' = (4,5) * 0.5[/tex]

[tex]R' = (4* 0.5,5* 0.5)[/tex]

[tex]R' = (2,2.5)[/tex]

Lastly, measure R' from the origin by adding the coordinates of P to R'

[tex]R' = (2+(-3),2.5+(-3))[/tex]

[tex]R' = (2-3,2.5-3)[/tex]

[tex]R' = (-1,-0.5)[/tex]

Dilation of a figure or image is to enlarge or shorter it from the original length by a scale factor.

The coordinate of the R' after the dilation is (-1,-0.5)

Dilation of a figure or image is to enlarge or shorter it from the original length by a scale factor.

Given information-

The points of PQRS are Q(-3,2), R(1,2), P(-3,-3), S(1,-3).

The given points are dilated. This dilation can be measured by subtracting the point P from each point . Thus the point of Q is,

[tex]Q'=Q-P\\Q'=(-3-(-3), 2-(-3))\\Q'=(0,5)[/tex]

Similarly,

[tex]R'=R-P= (1-(-3),2-(-3))=(4,5)\\P'=P-P=(-3-(-3), 3-(-3)=(0,0)\\S'=S-P=(1-(-3),-3-(-3))=(4,0)\\[/tex]

As the dilation factor is 0.5. Thus, the point of Q is,

[tex]Q"=(0.5)\times(0,5)=(0,2.5)[/tex]

Similarly,

[tex]R"=(0.5)\times(4,5)=(2,2.5)\\P"=(0.5)\times(0,0)=(0,0)\\S"=(0.5)\times(4,0)=(2,0)\\[/tex]

Add the points P back, to the above coordinate plane to get the dilation point. Thus the point of Q is,

[tex]Q'''=(0,+(-3), 2.5+(-3))\\Q'''=(-3,-0.5)[/tex]

Similarly,

[tex]R'''=(2+(-3),2.5+(-3))=(-1,-0.5)\\P'''=(0+(-3),0+(-3))=(-3,-3)\\S'''=(2+(-3),0+(-3))=(-1,-3)\\[/tex]

Thus the coordinate of the R' after the dilation is (-1,-0.5)

z = 10

x and z are opposite, x= -10, where as z = 10, Hence x times (-1) equals z.

An integer is a non-fractional number real number. It can be either negative or positive, it simply cannot be a fraction.

"w", "x", and "y" are negative, and hence less than zero.

Answer:Since -2 can not equal 0, there is no solution. The lines are parallel. It is an inconsistent system.

Step-by-step explanation:

The first step in solving a system of equations by substitution is solving one of the equations for one of the variables

x - y = 0 Equation 1

x - y + y = 0 +y Add y to each side

x = y Simplify

After solving an equation for one of the variables, substitute that value into the other equation. In this problem, I can substitute y for x.

x - y - 2 = 0 Equation 2

y - y - 2 = 0 Substitute the value of x from equation 1

0 - 2 = 0 Inverse Property of addition

Answer:

(-3,-4)

If it was on the y-axis it would be (3,4)

Step-by-step explanation:

Rx-axis (P) = (-3, -4)

"When we reflect a point about x-axis then the x-coordinate remains the same, but the y-coordinate changes its symbol."

For given example,

we have been given a point P = (-3, 4)

We need to find  Rx-axis (P)

That is we need to reflect given point about x-axis.

We know, when we reflect a point about x-axis then the x-coordinate remains the same, but the y-coordinate changes its symbol.

So, the reflected point would be (-3, -4)

Therefore, Rx-axis (P) = (-3, -4)
