The two expressions are equivalent.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

2x + 4 - 1 can be represented as 2x + 3

3 + x + x  can be represented as 3 + 2x

The two expressions are equivalent.

At x = 6

2x + 3    and     3 + 2x

2(6) + 3   and    3 + 2(6)

12 + 3     and     3 + 12

   15        and       15

Both are equal.

At x = 2

2x + 3    and     3 + 2x

2(2) + 3   and    3 + 2(2)

 4 + 3     and      3 + 4

    7        and        7

Both are equal.

Thus the two expressions are equivalent.

Answer:

if both expressions have the same value after submitting and simplifying for x = 6 and x = 2, then they are equivalent. Substitute 6 for each variable, 6 for each variable, x, in both expressions. The value on both expressions is 15. Now, substitute 2 for each variable, x, in both expressions. The value of both expressions is 7. Therefore, the expressions are equivalent.

Answer:10% of 82 is 820so 60% of 82 is 4800

Step-by-step explanation:

i hope im right

Step-by-step explanation:

Given that:

6(x - 1) - x = -21

Multiply the number outside of the brackets with numbers in the brackets on LHS.

⇛6x - 6 - x = -21

Shift constant from LHS to RHS, changing it's sign.

⇛6x - x = -21 + 6

Subtract the values on LHS and RHS.

⇛5x = -15

Shift the number 5 from LHS to RHS.

⇛x = -15/5

Therefore x = -3

Answer:

Distance traveled is equal to the length of wheel circumference as it “unrolls” along the ground as the wheel turns. One full turn of the wheel will move the robot one circumference's distance. Therefore, students will find the distance traveled by multiplying circumference by the number of rotations.

The expected value for each round, if there are two draws per round and the chips, are replaced after each draw is 0.4.

Given to us

Number of black chips = 2

Number of red chips = 3

Points are given for a black chip = +2

Points are given for a red chip = -1

We know that for each round there will be 2 draws, therefore, there will be four cases,

Case1:

Probability, when both the chips drawn are black,

[tex]\dfrac{2}{5} \times \dfrac{2}{5} = \dfrac{4}{25}[/tex]

Case2:

Probability, when the first chip is black and the next chip is red,

[tex]\dfrac{2}{5}\times \dfrac{3}{5}=\dfrac{6}{25}[/tex]

Case 3:

Probability, when the first chip is red and the next chip is black,

[tex]\dfrac{3}{5}\times \dfrac{2}{5}=\dfrac{6}{25}[/tex]

Case 4,

Probability, when both the chips drawn are red,

[tex]\dfrac{3}{5}\times \dfrac{3}{5}=\dfrac{9}{25}[/tex]

The expected value of each round can be found,

[tex]E(x) = (2+2)\dfrac{4}{25} + (2-1)\dfrac{6}{25} +(-1+2)\dfrac{6}{25} +(-1-1)\dfrac{9}{25}[/tex]

E(x) = 0.4

Hence, the expected value for each round, if there are two draws per round and the chips, are replaced after each draw is 0.4.

Answer:

AC = 24

Step-by-step explanation:

In a rectangle, the diagonals are the same so AC = BB

3x - 9 = x + 13

3x - x = 13 + 9

2x = 22

x = 11

AC = 3x - 9 = 3(11) - 9 = 33 - 9 = 24

Answer:

x = 6

Explanation:

3x - 3 = 15

3x = 15 + 3

3x = 18

x = 18 ÷ 3

x = 6

The value of x from the expression is 6

Given the equation

3x - 3 = 15

Add 3 to both sides

3x - 3 + 3 = 15 + 3

3x = 18

Simplify the result

3x = 18

Divide both sides by 3

3x/3 = 18/3

x = 6

Hence the value of x from the expression is 6

Answer:

x = 16

Step-by-step explanation:

the labeled angles are all exterior

the sum of all exterior angles always equals 360 degrees

9x+1 + 5x+12 + 10x-37 = 360

24x - 24 = 360

24x = 384

x = 16

so initially the paper is in full piece.

it is cut into half, which makes into 2. this is pattern 1.

then the halves is further divided in to 2.

then the total becomes 4. then the four pieces are cut into halves, which makes the total of 8 pieces, that is pattern 3..

is if we see the pattern it is a geometric progression.

Tn=ar²-¹ where the r is common ratio

and a is the first term. the question mentioned repeat 15 times.

1. 2

256, 1024, 4096

Step-by-step explanation:

I'm not sure what you need help with, since what you have written down is correct. However, if you are looking for an explanation, here it is:

x + 5 < -2

To solve for x, we have to get x on one side by itself. Whatever you do to one side, you have to do to the other. Let's get rid of 5 to get x by itself.

x + 5 < -2    (Subtract 5 from both sides)

x < -7

Perfect! Basically what this is saying, is that all the values x can equal have to be less than -7. The sign < means less than.

For the signs < (less than) and > (greater than), we use an open circle.

For the signs ≤ (less than or equal to) and ≥ (greater than or equal to), we use a closed circle.

This is why we use an open circle for this example since x is LESS THAN -7.

The arrow is pointing to the left because these numbers are less than -7.

Answer: f=78

Step-by-step explanation:

En un cuadrilatero la suma de los angulos internos es 180°

Ademas los angulos alternos internos so iguales.

Por lo tanto el angulo frente a 72° en diagonal tambien es 72°

Si sumamos esos dos angulos obrenemos 144°Si restamos este resultado de 360° obtenemos  360°-144=216 °

Finalmente debemos dividir entre dos los 216°

216/2 = 78°
