Answer:

a = 7

Step-by-step explanation:

3(1 - 2a) = -3a - 18

3 - 6a = - 3a - 18

Add 18 to each side:

3 + 18 - 6a = - 3a - 18 + 18

21 - 6a = - 3a

Add 6a to each side:

21 - 6a + 6a = - 3a + 6a

21 = 3a

3a = 21

Divide each side by 3:

3a ÷ 3 = 21 ÷ 3

a = 7

Answer:

2.6779*10^5

Step-by-step explanation:

2.69 * 10^5 - 1.21 * 10^3

This is 2.6779*10^5 :)

The difference between the areas of Texas and the area of Rhode Island is given by equation A = 2.6779 x 10⁵ miles²

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the area of Texas be p = 2.69 x 10⁵ miles²

Let the area of Rhode Island be q = 1.21 x 10³ miles

Now , the difference of areas A = p - q

On simplifying the equation , we get

The difference between the area of Texas and the area of Rhode Island A = 2.69 x 10⁵ miles² - 1.21 x 10³ miles

A = 2.69 x 10⁵ miles² - 1.21 x 10³ miles

A = 10³ ( 2.69 x 100 - 1.21 )

On further simplification , we get

A = 10³ ( 269 - 1.21 )

A = 267.79 x 10³

A = 2.6779 x 10⁵ miles²

Hence , the difference in areas is 2.6779 x 10⁵ miles²

Answer

b

Step-by-step explanation:

Answer:

B) There is an error in step 2.

Step-by-step explanation:

When solving 8x+10-6x+4=24, you have to first combine your like terms. These are 8x and -6x (giving you 2x) and 10 and 4 (giving you 14).

After combing your like terms, you now have the equation 2x+14=24.

You need to get x alone and the first step to do that is to subtract 14 from both sides of the equation. This cancels out 14 from the side with x on it and leaves you with 10 on the other side. Your equation is now 2x=10

This is where the student made the mistake. Instead of subtracting 14, they added 14.

The final step would be to divide by 2 on both sides.

At the end of the problem, you are left with x=5.

Answer:

Step-by-step explanation:

In general, if PQ is rotated to P'Q', the center of rotation (O) will be the point of intersection of the perpendicular bisectors of PP' and QQ'. The angle of rotation will be the angle POP', or QOQ'.

__

The correspondence between preimage vertices ABCD and image vertices can be found by naming the vertices in the same order (clockwise) from one whose correspondence you know.

Here, the correspondence between A and W is given. Vertices clockwise from W are WXYZ, so those are the image points corresponding to ABCD.

__

We note that the midpoints of AW and BX are coincident at the origin. That is, the perpendicular bisectors of these segments are coincident at the origin, so the origin (point O) is the center of rotation. The rotation angle is AOW, an angle that measures 180°.

__

The image point coordinates are the opposites of the preimage point coordinates.

  A(2, 2) ⇒ W(-2, -2)

  B(2, 5) ⇒ X(-2, -5)

  C(5, 5) ⇒ Y(-5, -5)

  D(5, 2) ⇒ Z(-5, -2)

This is another indication that the rotation is 180° about the origin, since that rotation results in the mapping ...

  (x, y) ⇒ (-x, -y) . . . . . rotation 180° about the origin

Answer:

Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.

Step-by-step explanation:

Given:

Length of the truck = 80 cm

Width of the truck = 60 cm

To find:

The longest walking stick that can be placed in the bottom of a truck.

Solution:

The longest walking stick that can be placed in the bottom of a truck is the diagonal of the truck.

We know that, the diagonal of a rectangle is:

[tex]d=\sqrt{l^2+w^2}[/tex]

Where, l is the length and w is the width.

Putting [tex]l=80[/tex] and [tex]w=60[/tex], we get

[tex]d=\sqrt{(80)^2+(60)^2}[/tex]

[tex]d=\sqrt{6400+3600}[/tex]

[tex]d=\sqrt{10000}[/tex]

[tex]d=100[/tex]

Therefore, the length of the longest walking stick that can be placed in the bottom of a truck is 100 cm.
