Mathematics
1 answer:
olga2289 [7]3 years ago
7 0

Answer/Step-by-step explanation:

The corresponding side lengths of two triangles are always equal. Apply this in solving for x

4. \frac{9}{6} = \frac{x}{5}

Cross multiply

6*x = 5*9

6x = 45

divide both sides by 6

y = 7.5

5. \frac{10}{8} = \frac{x}{11}

Cross multiply

8*x = 10*11

8x = 110

divide both sides by 8

x = 13.75

6. \frac{12}{x} = \frac{7}{4}

Cross multiply

x*7 = 12*4

7x = 48

divide both sides by 7

x = 6.86 (nearest hundredth)

Viktor [21]

Answer:

Ambitious

In this case, you have to multiply the price of the one way journey ($2.65) by 8 (as this is the number of individual journeys made in one week. It's gives you $21.20. As he has 1 bottle of water at $1.45 each day for four days, you have to multiply these together, giving you $5.80 You then have to add together $21.20 and $5.80, giving you $27. Therefore, it costs Edgar $27 a week

Luba_88 [7]

<u>Answer</u>:

A. y = \frac{-2}{3}x + 3

<u>Explanation</u>:

slope: \frac{y2-y1}{x2-x1}

         : \frac{1-3}{3-0}

         : \frac{-2}{3}

equation: y - y1 = m( x - x1 )

                y - 1 = \frac{-2}{3}( x - 3 )

                y = \frac{-2}{3}x + 3

What is 0.5 repeating as a fraction in simplest form
Solnce55 [7]

Answer:

5/9

Step-by-step explanation:

Start be letting x = 0.555...

Our original equation is:

x = 0.555...

There is only one digit repeating, the 5, so we multiply both sides of that equation by 10 and write it above the original equation.

10x = 5.555...

   x = 0.555...

Now we subtract the second equation from the first equation as written above.

9x = 5

Divide both sides by 9.

x = 5/9

0.555... = 5/9
