please mark me brainliest. Thank you

Answer:

1a) x = -41

1b) x = -1

1c) x = 29/3, or x = 9.66 in decimal form

1d) x = -4

----------------

2a) y = -3

2b) y = -60

2c) y = -83

2d) y = -50

Step-by-step explanation:

1a) y = x  + 11

-30 = x  + 11

-11           -11

------------------

-41 = x

1b) y = -2x - 32

-30 = -2x - 32

+32         +32

----------------------

2 = -2x

/-2   /-2

----------------------

-1 = x

1c) y = -3x - 1

-30 = -3x - 1

+1             +1

-----------------

-29 = -3x

/-3     /-3

------------------

29/3 = x

9.66 = x

1d) y = 5x - 10

-30 = 5x - 10

+10         +10

----------------------

-20 = 5x

/5      /5

----------------------

-4 = x

------------------------

2a) y = x + 3

y = -6 + 3

y = -3

2b) y = -2x - 72

y = -2(-6) - 72

y = 12 - 72

y = -60

2c) y = 3x - 65

y = 3(-6) - 65

y = -18 - 65

y = -83

2d) y = 4x - 26

y = 4(-6) - 26

y = -24 - 26

y = -50

Answer:

x<-7

Step-by-step explanation:

4 − (x + 2) < −3(x + 4)

4 − x - 2< −3x - 12

14 < - 2x

x<-7

Answer and Step-by-step explanation:

First, we need to solve both sides of the equation.

Distribute the negative to the x and the 2.

4 - x - 2 < -3(x + 4)

Distribute the -3 to the x and the 4.

4 - x - 2 < -3x - 12

Combine like terms.

2 - x < -3x - 12

Add 12 to both sides of the equation.

12 + 2 - x < -3x - 12 + 12

14 - x < -3x

Add x to both sides of the equation.

14 - x + x < -3x + x

14 < -2x

*Divide both sides of the equation by -2, and flip the sign.

-7 > x

-7 > x is the answer.

*How this works:

When we flip the sign, we really are just saving ourselves an extra step when dividing numbers (that are negative, only works when number is negative).

14 < -2x

If we were to add to x, and subtract 14, it will look like this:

2x < -14

Then when we divide by 2, we get:

x < -7

This is the same result, but it takes an extra step. Use this way if you forget why you need to flip the sign when dividing by a negative number.

Step-by-step explanation:

Question:- 22% of 150

Answer:-

[tex]22\% \: of \: 150[/tex]

In maths of means multiplication

[tex] \frac{22}{100} \times 150 \\ \frac{ \cancel{22}^{ \: \: \tiny{11}} }{ \cancel{100} {}^{\tiny{ \: \: 50}}} \times 150 \\ \frac{11}{ \cancel{50}^{ \: \: 1} } \times \cancel{150}^{ \: \: 3} \\ 11 \times 3 = 33[/tex]

Correct options is (D) 33

The value of 22 percentage of 150 is 33, option D is correct.

To find 22% of 150, we need to convert the percentage to a decimal and then multiply the result with 100.

Convert the percentage to a decimal.

To convert a percentage to a decimal, you divide it by 100.

In this case, 22% as a decimal:

= 22 ÷ 100

The result is 0.22.

= 0.22

Multiply the decimal by the number (150) you want to find the percentage of.

In this case, 0.22 (the decimal equivalent of 22%) multiplied by 150:

=150×0.22

=33

Therefore, the value of 22% of 150 is equal to 33. option D is correct.

Violet will need to use 300 tiles for tabletop.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it is given that,

Number of glass tiles Violet has = 30

Now,she would like to mosaic tile a tabletop with 10 times that number of tiles

So, number of tiles become = 10 times Number of glass tiles Violet has

⇒ number of tiles become = 10*30

⇒ number of tiles become = 300 tiles

Thus, Violet will need to use 300 tiles for tabletop.

Answer:

The correct scientific notation form of the given numeral using only 2 significant figures is 8.4×10⁶.

8.4×10⁶ is the right answer

Step-by-step explanation:

→We can move the decimal point 6 units towards the left to get the number.

→Then we can multiply the number by 10 to the power 6 to get the required answer.

Two "factors" are multiplies together to product another number (the product).  So, for example, the prime factors of 10 are 2 and 5.  Prime factors that, themselves, have only factors of 1 and themselves.  Non-prime numbers, like 10, have prime factors.  Note that 1 is a factor of all integers.

If the two factors are equal (the same), like 4*4=16, then each of them is called a "square root."

Note: a cube root is one of three equal factors of a number, for example, 2 is the cube root of 8 (that is, 2*2*2=8).

Practice:

   What is the square root of 49?

   What is the square root of 100?

   What is the square root of 625?

   Memorize the squares of the numbers from 1 to 10, or 1 to 20  -- that will be very helpful in math classes.

Answer:

1) 68+28 = 96 cards

2) 278.32 - 3698 is a question that gives a negative answer

   We rewrite as;

    278.32

-  3698,00 =  see 78.32 - 98.00 turns to -19.68 and 200 - 3600 = -3400

 -  3400 -+19.68 = -  3419.68

We add the last bit as it is the remainder of 3400 if done separately.

2b) With adding both numbers  278..32 + 3698 = 3976.32
