Answer:

x = 3.6

B. {7.88}

Step-by-step explanation:

\frac{6}{x}= \frac{10}{6}

x · 10 = 6 · 6

10x = 36

10x ÷ 10 = 36 ÷ 10

x = 3.6

\frac{9}{8} =\frac{x}{7}

8 · x = 9 · 7

8x = 63

8x ÷ 8 = 63 ÷ 8

x=7\frac{7}{8} or x = 7.875

7.875 rounded to the nearest tenth is 7.88.

statuscvo [17]

Answer:

0.3 chance of not drawing a blue marble.

Step-by-step explanation:

This problem can be found using the theoretical probability formula.

Now all you have to do is input the numbers into the equation.

P(not drawing a blue marble) = <u>3</u>

                                                  10

3/10 is equal to 0.3 as a decimal.

JulsSmile [24]

Answer:

1 minute

Step-by-step explanation:

We can see that Lisa types 165 words in 3 mins.

So she types 55 words in 1 minute.

How did I work that out?

Well, all you really do is \frac {165}{3} which is equal to \frac{55}{1} if you divide top and bottom by 3. Anything divided by 1 is itself.
