Answer:

5x² - 31x + 30

Step-by-step explanation:

(5 - x)(6 - 5x)

= 30 - 25x - 6x + 5x²

= 30 - 31x + 5x²

= 5x² - 31x + 30

What is the solution to the system please help

IrinaVladis [17]

Answer:

$(-\frac{50}{13},-\frac{12}{13})$

Step-by-step explanation:

To start, you need to find the equation of both of these lines. For the orange one, the slope can be found with the points (-5,0) and (0,-4), where there is a drop of 4 for a run of 5. This is a slope of -4/5, and a y-intercept of -4. For the purple line, you can use the points (-2,0) and (0,1), where there is a rise of 1 for a run of 2 or a slope of 1/2 and a y intercept of 1. Therefore, the two equations are:

$y=-\frac{4}{5}x-4$

$y=\frac{1}{2}x+1$

You can now set them equal to each other:

$-\frac{4}{5}x-4=\frac{1}{2}x+1$

Add 4 to both sides:

$-\frac{4}{5}x=\frac{1}{2}x+5$

Multiply both sides by 2:

$-\frac{8}{5}x=x+10$

Multiply both sides by 5:

$-8x=5x+50$

Subtract 5x from both sides:

$-13x=50$

Divide both sides by -13:

$x=-\frac{50}{13}$

$y=-\frac{12}{13}$

Hope this helps!

Hunter-Best [27]

Answer:

To represent parts of whole numbers, we use fractions.

So if 4 kids are sharing 3 cookies, what happens?

First, we divide one cookie into four equal parts, and give one part to each kid. Then we do the same with the second cookie, and then with the third one.

In the end, each kid will have three pieces. Each piece is a whole cookie divided into four equal parts.

So we represent this amount as

3 (Number of parts) & 4 (How many equal parts the whole is divided into)

as a fraction

A fraction is made of two numbers :
