Answer:

change the equation into one variable.

2 y equals 10 + x

y equals 5 + x by 2

now put that into the second equation

-3x + b parentheses 5 + x / 2 equals 11

-3x+b(5+ x/2)

-3x + b5 + bx/2 = 11

Assume that 11 people, including the husband and wife pair, apply for 5 sales positions. People are hired at random. (1) what is

Andrew [12]

The probability that both the husband and wife are hired is $\frac{2}{11}$

Explanation

Total number of people = 11 and total number of sales positions = 5

So, the total possible number of ways for selecting 5 people from 11 people will be: $^1^1C_{5}$

Now if both the husband and wife are hired, then it means the remaining (5-2)= 3 positions are filled from the remaining (11 -2) = 9 people.

So, the possible number of ways for selecting 3 people from 9 people will be: $^9C_{3}$

Thus, the probability $= \frac{^9C_{3}}{^1^1C_{5}}=\frac{84}{462}=\frac{2}{11}$

Please help im so confused (need asap)

$\qquad\qquad\huge\underline{{\sf Answer}}$

Let's solve ~

$\qquad \tt \dashrightarrow \:10 {x}^{2} - 25x + 15 = 0$

$\qquad \tt \dashrightarrow \:5(2x {}^{2} - 5x + 3) = 0$

$\qquad \tt \dashrightarrow \:2x {}^{2} - 5x + 3 = 0$

$\qquad \tt \dashrightarrow \:2x {}^{2} - 3x - 2x + 3 = 0$

$\qquad \tt \dashrightarrow \:x(2x - 3) - 1(2x - 3) = 0$

$\qquad \tt \dashrightarrow \:(x - 1)(2x - 3) = 0$

Therefore, the required factors are ~ (x - 1) and (2x - 3)

So, correct choice is B

It just wants you to simplify your expression. Does every single variable have a number in common?
