5x + 2(11-1) = 30Solve The Equation/Explain Each Step
Answer 2

Answer:

2.

Step-by-step explanation:

5x + 2(11-1) = 30

First, solve the ones inside the bracket:

11 - 1 = 10

Next, multiply the number inside the bracket by the number next to bracket:

2 × 10 = 20

The equation will now be:

5x + 20 = 30

Since 5x and 20 are not like terms, carry +20 over to the other side making it 30 - 20:

5x = 30 - 20

5x = 10

Now, divide both sides by the coefficient of x (5):

5x/5 = 10/5

x = 2

The answer to the equation is 2.

A

B

C

45º

D

360º

Answers

Answer:

option (c)

Step-by-step explanation:

Given,

ABCD is a square.

AC and BD are diagonals

We know that,

Sides of the square make 90 degrees with each other.

And Diagonals bisect the opposite angles of the square.

Now,

[tex]\angle ABD = \dfrac{\angle ABC}{2}[/tex]

[tex]\angle ABC = 90^\circ[/tex]

[tex]\angle ABD = \dfrac{\angle ABC}{2}[/tex]

[tex]\angle ABD = \dfrac{90^\circ}{2}[/tex]

[tex]\angle ABD = 45^\circ[/tex]

Hence, option (c) is correct.

Complete the square x² + 16.0

Answers

Answer:

x^2 + 16x + 32

Step-by-step explanation:

I am going to guess this is from factoring.

In which you need to x's multiplied together to get x^2. So you have:

(x+?) (x+?)

to get 16x you need two 8x's in your factoring square. so it would be

(x+8) (x+8)

Now you found out what you were mulitpling together, then you solve. The final part is multiplying 8 by 8, which is 32.

Wwhich expression uses the associative property to make it easier to evaluate 8(1/2x1/3)?
A.8/3(2x33)
B.(8x1/2)1/3.
C.8(1/3x1/2)
D.(8x1/3)1/2​

Answers

The correct answer would be B. (8×1/2)1/3.

Step-by-step explanation:

8 * [(1/2) * (1/3)]

= [8 * (1/2)] * (1/3)

= 4 * (1/3)

= 4/3.

The answer is B because it is easier to calculate 8 * (1/2), which is dividing 8 by 2 to get 4.

There are two ways to solve this u can divide the 30 by 6 (30/6=5) or you can ask yourself what numbers times 6 is equal to 30? 6 time ? =30 which is also equal to 5.
So that would make (c) x=5 the correct answer

We need to find the sum of the opposite of -10 t and t - 10t.

The opposite of -10 t is 10 t.

[tex]10t+(t-10t)[/tex]

Remove the parenthesis.

[tex]10t+t-10t[/tex]

Through pythogoras theorem

a^2+b^2=c^2

20^2+16^2=c^2

c^2=400+256

c^2= 656

c= square root of 656

c=25.6 inches or 30 inches

Missing side 25.6 inches or 30 inches

c^2 = a^2 + b^2

c^2 = 16^2 + 20^2

c^2 = 256 + 400

c^2 = 656

Now, square root both sides to find the missing length of c or the hypontenuse.
