-5x is - 40 + 3x Find x

Mathematics
1 answer:
irina [24]2 years ago
8 0

Answer: x = 5

Step-by-step explanation:

1. Set the two given expressions equal to each other (because the problem says they are interchangeable)

-5x = -40+3x

2. Subtract 3x from -5x to have x on one side of the equation.

-8x = -40

3. Divide each side by -8 to get the value of x.

x = 5

×-2+2×+4+2×-2=180 what does x equal in this equation.
daser333 [38]

Answer:

<u>x = 36</u>

Here's how I got that:

<em>    - Group like terms -</em>

x - 2 + 2x + 4 + 2x - 2 = 180

                    ↓

      5x - 2 + 4 - 2 = 180

                    ↓

              5x = 180

<em>  - Divide both sides by 5 - </em>

<em>         </em>  5x/5 = 180/5

                   ↓

<em>                </em><u><em>x </em></u><u>= 36</u>

<em>~ That's all folks ~</em>

IMPORTANT <br><br>[how do you]Find sin theta if tan theta = 3/4
zvonat [6]
\bf tan(\theta )=\cfrac{\stackrel{opposite}{3}}{\stackrel{adjacent}{4}}\impliedby \textit{let's find the \underline{hypotenuse}}&#10;\\\\\\&#10;\textit{using the pythagorean theorem}\\\\&#10;c^2=a^2+b^2\implies c=\sqrt{a^2+b^2}&#10;\qquad &#10;\begin{cases}&#10;c=hypotenuse\\&#10;a=adjacent\\&#10;b=opposite\\&#10;\end{cases}&#10;\\\\\\&#10;c=\sqrt{3^2+4^2}\implies c=5&#10;\\\\\\&#10;sin(\theta )=\cfrac{\stackrel{opposite}{3}}{\stackrel{hypotenuse}{5}}

bear in mind that, though the square has two valid roots, one negative and one positive, the hypotenuse is just a radius distance, and therefore is never negative.

How do I factor the quadratic equation
anastassius [24]
Factor the following:
10 y^2 - 35 y + 30
Factor 5 out of 10 y^2 - 35 y + 30:
5 (2 y^2 - 7 y + 6)
Factor the quadratic 2 y^2 - 7 y + 6. 
The coefficient of y^2 is 2 and the constant term is 6. 
The product of 2 and 6 is 12. 
The factors of 12 which sum to -7 are -3 and -4. So 2 y^2 - 7 y + 6 = 2 y^2 - 4 y - 3 y + 6 = y (2 y - 3) - 2 (2 y - 3):
5 y (2 y - 3) - 2 (2 y - 3)
Factor 2 y - 3 from y (2 y - 3) - 2 (2 y - 3):
Answer:  5 (2 y - 3) (y - 2)
