I'm assuming you want that solved. I will try to help you but I don't speak Spanish.

4/x+7=-1/x+2

I'm assuming that x+7 is all part of the denominator, and x+2 is all part of the other denominator...
Like this:
4/(x+7)=-1/(x+2)

4(x+2)=-1(x+7) (cross multiply)

4x+8=-x-7 (distribute)

5x+8=-7 (add 1x to both sides)

5x=-15 (subtract 8 from both sides)

x=-3 (divide both sides by 5)


I hope this helps. I don't speak Spanish, but I hope you speak English so that I can help you!

Best of luck!

The quotient of a number x and 4 is at most 5. An inequality is?
Shalnov [3]

Answer:

The inequality can be represented as:

\frac{x}{4}\leq5

Solution for the inequality:

x\leq20

Step-by-step explanation:

Given :

The quotient of a number x and 4 is at most 5.

To write an inequality for the given statement.

Solution:

The quotient of two variables a and b can be represented as : \frac{a}{b}

Thus the quotient of the number x and 4 can be represented as:

⇒  \frac{x}{4}

The quotient is at most 5 which means it is less than or equal to 5.

Therefore, the inequality can be represented as:

\frac{x}{4}\leq5

<em>Solving for</em> x.

Multiplying both sides with 4.

4\times \frac{x}{4}\leq5\times 4

x\leq20

Thus, the number must be at most 20.

When solving the equation 4(3x^2 + 2) - 9 = 8x^2 + 7, Emily wrote
Alenkinab [10]
1 addition property of equality

Since there the -9 disappeared on the left and the +7 changed by 9 to a +16, 9 must have been added to both sides of the equation, and the addition property of equality states that the equation remains true when the same thing is added to both sides.
