Sean, Ryan, and Justin shared a sum of money in the ratio 3 : 4 : 5. If Sean received $30, what was the sum of money shared?

Solnce55 [7]

In order to solve this problem, you need to find out how 3 of something is 30
In this case, you multiply 10.
Sean= 3×10=30
Ryan= 4×10=40
Justin= 5×10= 50
30+40+50= 120
The answer is $120
Hope this helps

Which system of linear inequalities is represented by the graph?

pentagon [3]

Answer:

Option D- y > x – 2 and y < x + 1

Step-by-step explanation:

To determine : Which system of linear inequalities is represented by the graph?

Solution : First we examine the graph

The shaded region in purple is drawn using two line

The first line above the origin passing through the points (0,1) and (-1,0)

The equation of line passing through two points is $y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

$y-1=\frac{0-1}{-1-0}(x-0)$

$y-1=x$

So, the equation of that line $y = x + 1$

The second line below the origin passing through the points (0,-2) and (2,0)

The equation of line passing through two points is $y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

$y-(-2)=\frac{0-(-2)}{2-0}(x-0)$

$y+2=x$

So, the equation of that line $y=x-2$

Now, to check the system of inequality substitute point (x,y)=(0,0)

First equation $y = x + 1$

$0$ means $y< x + 1$

Second equation $y = x-2$

$0>-2$ means $y> x-2$

Therefore, Option D is correct.

The linear inequalities of the system is y > x-2 and y < x + 1
