If we simply it, then it would be
3 + 2x + 6 + x = 15, which equals
3x + 6 + 3 = 15,
3x + 9 = 15,
if we subtract 9 from 15, we get 6. If we divide 3x by 3, and 6 by 3, we get 2.
Therefore x = 2, and we know there is a 10/15 chance to get a humbug, or a 1/3 chance.
Hope this helped.

Answer:

Takeru bought 72 eggs and baked 18 soufflés .

Step-by-step explanation:

Let

e = number of eggs Takeru bought.

s = number of soufflés Takeru bought.

Then we know that Takeru bought 4 times as many eggs as he baked soufflés, therefore:

$e=4s.$

And since for every soufflés Takeru bakes he uses 3 eggs, and after backing he has 18 eggs left, we have:

$e-3s=18$ <em>This says that from $e$ eggs there are 18 eggs left after Tkeru used three eggs for each soufflé.</em>

Now we have two equations:

$(1).e=4s.$

$(2).e-3s=18$

We put the value of e from equation (1) into equation (2) and solve for s and get:

$s=18$

$e=4s=4*18=72.$

Thus

Number of eggs Takeru bought = 72.

Number of soufflés Takeru bought = 18.

Write the equation that passes through the following points:<br><br> (5,0) and (−10,−5)

Vikentia [17]

Answer:

The answer is:

$y = \frac{1}{3} x - \frac{5}{3}$

Step-by-step explanation:

❃Incase you forgot what the linear equation formula is ☟

$y = mx + b$

❃Incase you also forgot, The is what the slope formula is ☟

$m = \frac{y_2 - y_1 }{x_2 - x_1}$

➊ First: We are going to be solving for the slope.

$m = \frac{ - 5 - 0}{ - 10 - 5} = \frac{ - 5}{ - 15} = \frac{1}{3}$

➋Second: We find the y-intercept.

$y = mx + b \\ 0 = \frac{1}{3} (5) + b \\ 0 = \frac{5}{3} + b \\ \frac{ - \frac{5}{3} = - \frac{5}{3 } \: \: \: \: \: \: \: \: \: \: \: \: }{ - \frac{5}{3} = b}$

➌Third: Plug in.

$y = \frac{1}{3} x - \frac{5}{3}$

Let's call the first unknown integer x and the second one y.

"Four times an unknown integer"

We can write it as 4x

"Multiplied by three times the unknown integer plus a different unknown integer"

4x is multiplied by 3x+y, so 4x(3x+y)=12x²+4xy

"Equals 100."

12x²+4xy=100

And so the answer is C: 12x²+4xy-100=0

If x/5+6=-14 then x equals

yanalaym [24]

Answer:

x = - 100

Step-by-step explanation:

Given

$\frac{x}{5}$ + 6 = - 14 ( subtract 6 from both sides )

$\frac{x}{5}$ = - 20

Multiply both sides by 5 to clear the fraction

x = 5 × - 20 = - 100
