$\bf -3-(-8)-(-2)=x\implies \stackrel{\mathbb{PEMDAS}}{-3+8-(-2)=x\implies -3+8+2=x}
\\\\\\
5+2=x\implies 7=x$

Multiplication first, from left to right, and then Adds and Substractions last from left to right

- 3 - (- 8) - (- 2) = x

Distribute the negatives to the numbers in the parentheses.

- 3 + 8 + 2
- 3 + 10
7

x = 7

Answer:

Equation: 15 - f = n

Answer: n = 9

Step-by-step explanation:

The question is asking to write the equation. The equation would be

"15 - f = n" where f shirts folded

n = shirts remaining to fold

Then the question has gave us the value of f and has told us to solve it. Below is the solution.

15 - 6 = n

=> n = 9

Therefore, there is 9 shirts remaining after 6 of them are folded.

What did we solve?

We wrote our equation and solved what was required in the question.

I hoped this helped.

If possible... May I have brainliest :)

The measure of an angle is seventy-one times the measure of its supplementary angle. What is the measure of each angle?

Degger [83]

Answer:

2 degrees and 178 degrees.

Step-by-step explanation:

So, remember if 2 angles are supplementary, they equal 180 degrees. Let's call the smaller angle x, meaning the bigger angle, which is 89 times the size of the smaller angle, would be 89x. Now let's put that into an equation.

180 = x + 89x

We now have to group the x's together:

180 = 90x

Now in order to determine x, we have to divide by 90 on both sides.

X= 2

So we know that the smaller angle is 2, meaning that if the larger angle is 89 times the size, the larger angle would be 178.

So the formula for a volume of a sphere is 4/3 times pi times the radius cubed.
step one: 4/3 times 3.14 = 4.18666666667
Step two: then you cube 8.5 and get 592.45
the final answer is 2,480.3906

$\displaystyle\\Answer:\ x=\sqrt{2}\ \ \ \ \ x=-\sqrt{2}\ \ \ \ \ x=\frac{ln5}{2}$

Step-by-step explanation:

$5x^2-x^2e^{2x}+2e^{2x}=10$

$Let:\ x^2=t \ \ \ \ \ e^{2x}=v\\Hence,\\5t-tv+2v^2=10\\5t-tv+2v^2-10=10-10\\5t-tv-10+2v^2=0\\t(5-v)-2(5-v)=0\\(5-v)(t-2)=0\\5-v=0\\5-v+v=0+v\\5=v\\5=e^{2x}$

Prologarithmize both parts of the equation:

$ln5=lne^{2x}\\ln5=2x*lne\\ln5=2x*1\\ln5=2x\\$

Divide both parts of the equation by 2:

$\displaystyle\\x=\frac{ln5}{2}$

$t-2=0\\t-2+2=0+2\\t=2\\x^2=2\\x=\sqrt{2} \\x=-\sqrt{2}$
