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.

Answer:

8.4 × 10^6

Step-by-step explanation:

Use floating-point system in which numbers are expressed as products consisting of a number between 1 and 10 multiplied by an appropriate power of 10 (as in 1.591 × 10−20)

Hope this helps <3

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.

Answer:

38

Step-by-step explanation:

4 + 34, 4 + 34, 20 + 18

38, 38, 38

Answer:

your answer would be 7285.63

Having two periods means it has two groups of digits separated by a comma.

6 digits would be xxx,xxx

An 8 worth 80 means the 8 is in the tens place.

And you have a 2 in the hundreds place.

All other digits can be any number.

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

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:

? = 10

Step-by-step explanation:

7 + ? × 5 + 9 = 66

Treat ? as a variable, and solve for ?.

Answer:

7

Step-by-step explanation:

3/5(t+18)  = -3(2-t)                   Distribute

3/5t + 10 4/5 = -6 + 3t            Subtract 3/5t in both sides

10 4/5 = -6 + 2 2/5t                Add 6 on both sides

16 4/5 = 2 2/5t                       Divide

t = 7

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.
