K. 48-24=24

I. 48+24=72×2= (144) so 144

An equation is formed of two equal expressions. The total number of marbles that Ivan had at the first is 40.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the number of marbles with Katherine be represented by k, while the number of marbles with Ivan is represented by x.

Given that the total number of marbles available with Katherine and Ivan is 96. Therefore, we can write,

k + x = 96

Solving the equation for k,

k = 96 - x

Further, Katherine lost 24 marbles to Ivan during a game and at the end of the game, Ivan had twice as many marbles as Katherine. Therefore, we can write the equation as,

2(k - 24) = (x + 24)

2k - 48 = x + 24

Substituting the value of k,

2(96 - x) - 48 = x + 24

192 - 2x - 48 = x + 24

192 - 48 - 24 = x + 2x

3x = 120

x = 120/3

x = 40

Hence, the total number of marbles that Ivan had at the first is 40.

Answer:

30 guests

Step-by-step explanation:

If each guest eats 9/10 lbs of chocolate, then they eat 0.9 lbs of chocolate. We have 27 lbs of chocolate to be eaten.

To solve this, simply:

[tex]\frac{27}{.9} =30[/tex]

where 27 lbs is divided by 0.9lbs per guest to equal 30 quests.

Answer:

C. x+8=3x

Step by step explanation:

First, subtract 8 from both sides of the equation

x+8=3x

x+8-8=3x-8

Then, simplify it by subtracting again

x+8-8=3x-8

x=3x-8

Then, subtract 3x from both sides of the equation

x=3x-8

x-3x=3x-8-3x

Then, simplify by combining the terms

x-3x=3x-8-3x

-2x=3x-8-3x

-2x=3x-8-3x

-2x= -8

Then, divide both sides of the equation by the same term

-2x= -8

-2x/-2 = -8/-2

Then, simplify by cancling terms that are in both the numerator and denominator

-2x/-2 = -8/-2

x= -8/-2

Finally, divide the numbers

x= -8/-2

x=4

And that's your answer! :)

Answer:

x = 1/5

y = 6

Step-by-step explanation:

System:

{5x + y = 7

{20x + 2 = y

First equation:

5x + y = 7 -> y = -5x + 7

Plug into second equation:

20x + 2 = -5x + 7

Subtract 2 from both sides:

20x = -5x + 5

Add 5x to both sides:

25x = 5

Divde both sides by 25:

x = 5/25 -> 1/5

~~~~~~~~~~~~~~~~~~~~~~~~~~~`

Come back to the first equation:

5x + y = 7

Plus in our x:

5(1/5) + y = 7

Multiply:

1 + y = 7

Subtract 1 from both sides:

y = 6

Step-by-step explanation:

what is THE partial product ? there is a mistake in your problem description.

it must read "what are valid partial products".

1262×3 has the following partial products :

1000×3 = 3000

200×3 = 600

60 × 3 = 180

2×3 = 6

-----------

3786

so, D seems to be the best answer, because both numbers are partial products here.

A, B and C have each only one correct.

Answer: -6x

Step-by-step explanation: Since when x is 0, the function's output is 0, the function can only have terms with x in it. You then notice a pattern that x is always being multiplied by -6. You could also use point slope form to solve it, either way you get f(x)=-6x

Answer:

f(x) = -6x

Step-by-step explanation:

The linear equation given in the form of a table is shown as:

[tex]\left[\begin{array}{ccc}x&f(x)\\0&0\\1&-6\\2&-12\\3&-18\end{array}\right][/tex]

Because the equation is linear, in order to find the equation written in slope-intercept form, divide the rise (f(x)) by the run (x):

0 ÷ 0 = 8

-6 ÷ 1 = 8

-12 ÷ 2 = 8

-18 ÷ 3 = 8

Because the quotient for each relation is -6, the linear equation can be written as f(x) = -6x.

Answer:

1 x 1 = 1.
