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.

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

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

+1             +1

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

-29 = -3x

/-3     /-3

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

29/3 = x

9.66 = x

-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

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.

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:

12:18 and 10:12 (i think)

Step-by-step explanation:

After converting the given ratios in their simplest form, the equivalent form of 2:3 we get 12:18.

To find the simplest form of a fraction, you have to simplify the numerator and denominator to their lowest terms and keep dividing until you can no longer simplify the fraction any further.

The given ratios are,

12:18,

3:21,

10:12

For the ratio 12:18,

Simplify it by finding the greatest common divisor (GCD) of 12 and 18.

The GCD of 12 and 18 is 6.

By dividing both numbers by 6, we get the smallest ratio of 2:3.

Moving to the ratio of 3:21,

Find the GCD of 3 and 21, which is 3.

Dividing both numbers by 3 results in the smallest ratio of 1:7.

Find the smallest ratio for 10:12.

The GCD of 10 and 12 is 2.

Dividing both numbers by 2 gives us the smallest ratio of 5:6.

Hence, the simplest form of ratios for the given ratios are:

12:18 = 2:3,

3:21 = 1:7,

10:12 = 5:6.

Hence,

The ratio equivalent to 2:3 is 12:18.

Answer:

Step-by-step explanation:

[tex]\frac{x+3}{3} =5- \frac{x-3}{6} \\(\frac{x+3}{3}) *6 =5 - (x-3)[/tex]

[tex]2x+6 = 5 - x+3[/tex]

Answer:

none

Step-by-step explanation:

We can start by multiplying both side of the equation by 6 in order to remove the fractions.

[tex]6*\frac{x+3}{3} = 6(5 - \frac{x-3}{6})[/tex]

[tex]2(x + 3) = 30 - 6*\frac{x-3}{6}[/tex]

[tex]2x + 6 = 30 -(x - 3)[/tex]

[tex]2x + 6 = 30 - x + 3[/tex]

Now, we can try to see if this equation is equivalent to the other options.

Every option has the left side as 2x - 6. In order to get that, we need to subtract 12 on both sides:

[tex]2x - 6 = 30 - x + 3 - 12[/tex]

This simplifies to

[tex]2x-6 = 18 - x + 3[/tex]

This is not the same as any of the options shown.

We can check this by solving the equations.

2x - 6 = 18 - x + 3

3x = 6 + 18 + 3

3x = 27

x = 9

Now, the first option:

2x - 6 = 10 - x - 3

3x = 6 + 10 - 3

3x = 13

x = 13/3

The second option is the exact same as the third, so they would have the same solution:

2x - 6 = 30 - x- 3

3x = 6 + 30 - 3

3x= 33

x = 11

Since none of the options have the answer 9, they are not equivalent to the equation shown.

Answer: 5

Explanation: You would need to evaluate & simplify the expression.

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.
