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:

3 1/24

Step-by-step explanation:

-7/8 + (-2 1/6)

~Rewrite

-7/8 - 2 1/6

-7/8 - 13/6

~Find common denominators

-21/24 - 52/24

~Subtract

-73/24

Best of Luck!

Answer:

-3 1/24

Step-by-step explanation:

- 7/8 + -2 1/6

= (0 + -2) + (-7/8 + -1/6)

= -2 + -7x3/ 8 x 3 + -1 x 4 / 6x4

= -2 + -21/24 + -4 / 24

= -2 + -21 + -24

          ------------

              24

= -2 + -25/24

= -2 + -1  1/24

= -3 1/24

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

Answer:

d =  |p^3|

Step-by-step explanation:

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

The correct equation that Jordan can use to solve the division problem 42 divided by 7 is:

? x 7 = 42

So, the correct equation is option 3) ? x 7 = 42.

Given that, Jordan has to solve this division problem: 42 divided by 7 = ?

In this case, Jordan needs to find the value of the missing factor, which represents how many times 7 can be multiplied to get 42.

Therefore, he can use the equation:

? x 7 = 42

This equation represents the inverse operation of division, which is multiplication.

When we know one factor (7) and the product (42), we can use multiplication to find the missing factor (the quotient).

By solving for the missing factor, he will find the correct answer to the division problem:

The missing factor = 42 / 7 = 6

So, the correct equation is option 3) ? x 7 = 42.

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:

? = 10

Step-by-step explanation:

7 + ? × 5 + 9 = 66

Treat ? as a variable, and solve for ?.

5? + 16 = 66

5? = 50

? = 50/5

? = 10

The answer is : 40:10

*multiply by 2

If helpful, brainliest please !

Answer:

40:10 & 8:2

Step-by-step explanation:

20 * 2 = 40

5 * 2 = 10

8 * 2.5 = 20

2 * 2.5 = 5

2:1 does not work because only 2 * 10 = 20, but 1 *10 = 10 and there is no 10. There is only 5.
