Answer:

-9 =x

Step-by-step explanation:

We know these are similar triangles

We can use ratio's to solve

Let CS = y and XR = y+y or 2y

y x+19

------ = ------------

2y x+29

We can simplify the ratio on the left by dividing by y

1 x+19

------ = ------------

2 x+29

Using cross products

1(x+29) = 2(x+19)

Distribute

x+29 = 2x+38

Subtract x from each side

x-x+29 = 2x-x+38

29 = x+38

Subtract 38 from each side

29-38= x+38-38

-9 =x

The ratio of Aziz's money to Osman's money was 2:1 at first. After Aziz spent $10 ratio became 4:3. How much money did each boy

Dvinal [7]

Answer:

Aziz's money was $30

Osman's money was $15

Step-by-step explanation:

Let

x-----> Aziz's money at first

y-----> Osman's money

we know that

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

$x=2y$ ------> equation A

$\frac{x-10}{y}=\frac{4}{3}$ -----> equation B

substitute equation A in equation B and solve for y

$\frac{2y-10}{y}=\frac{4}{3}\\ \\6y-30=4y\\ \\6y-4y=30\\ \\2y=30\\ \\ y=15$

Find the value of x

$x=2(15)=30$

therefore

At first

Aziz's money was $30

Osman's money was $15

If the slope of a line is -1/4,<br>find x when (x,2) and (1/2,6)

Alecsey [184]

Use slope formula:
m = (y2-y1) / (x2-x1)
-1/4 = 6-2 / 1/2 - x
-1/4 = 4 / 1/2 - x
-1(1/2 - x) = 4(4)
-1/2 + x = 16

x = 16 1/2 or 33/2
