1/3 ( x - 10) = -4 ???

Pepsi [2]

Answer:

$x = - 2$

Step-by-step explanation:

1) Simplify 1/3 ( x - 10) to x-10/3.

$\frac{x - 10}{3} = - 4$

2) Multiply both sides by 3.

$x - 10 = - 4 \times 3$

Simplify 4 × 3 to 12.

$x - 10 = - 12$

4) Add 10 to both sides.

$x = - 12 + 10$

5) Simplify -12 + 10 to -2.

$x = - 2$

So, therefor, the answer is, x = -2.

A club with five men and six women wish to form a committee. The number of men must be between 1 and 3 (inclusive), and the numb

Softa [21]

Answer:

1250 different committees can be formed

Step-by-step explanation:

We are told that the club has 5 men and 6 women.

Now we want to choose number of men between 1 and 3 with both inclusive and number of women between 2 and 4 with both inclusive.

We'll use the combination formula;

C(n, r) = n! / [r! (n - r)!]

Where, n = population and r = picks

Thus, we'll multiply the results of the women and men together. And so we have:this gives us ;

(5C1 + 5C2 + 5C3) * (6C2 + 6C3 + 6C4) = (5 + 10 + 10) * (15 + 20 + 15) = 25 * 50 = 1250 ways

Answer:

10v² - 27v - 17vx - 20x²

Step-by-step explanation:

Given

(5v + 4x)(2v - 5x - 3)

Each term in the second parenthesis is multiplied by each term in the first parenthesis, that is

5v(2v - 5x - 3) + 4x(2v - 5x - 3) ← distribute both parenthesis

= 10v² - 25vx - 15v + 8vx - 20x² - 12x ← collect like terms

= 10v² - 15v - 17vx - 12x - 20x²
