Answer:

3/10

Step-by-step explanation:

The first thing that you need to do is to find the common denominator of the two fractions. The least common multiple of 2 and 5 is 10, so we can express the new equation as 15/10-12/10=3/10. Hope this helps!

Answer:

\frac{3}{10}

Step-by-step explanation:

<u>Step 1:  Get Common Denominators </u>

\frac{3}{2} - \frac{6}{5}

\frac{3*5}{2*5} - \frac{6*2}{5*2}

\frac{15}{10} - \frac{12}{10}

<u>Step 2:  Combine the two numbers together </u>

\frac{15}{10} - \frac{12}{10}

\frac{3}{10}

Answer:  \frac{3}{10}

A survey of 100 students was taken concerning their knowledge of foreign languages. The results were as follows: 30 know French1
Sati [7]
35 students would not know any of the three languages, because if 30 know French, 19 knew German, and 16 knew Russian, that must mean that 65 students know at least one of the three languages. So you subtract 65 from 100 and end up with 35

I need help on 9-11 please
lisabon 2012 [21]
Hello! I would love to help!


9. Basically, it is asking us to multiply 5.2 by 46.

5.2*46=239.2

So, your answer is 239.2 inches.


10. First, let's find out how many blocks she has left to run by subtracting the number of blocks she has already ran by the number of total blocks.

60-18=42

So Susan has 42 blocks left to run. Now, let's divide that by 2 since she can run 2 blocks per minute.

42/2=21

So, the answer is 21 minutes.


11. Let's set up an equation: We know that she will automatically pay $49.95 per month, plus $0.15 per additional minute. We also know her final total for the month was $61.20:

49.95+0.15m=61.20

Let's solve! Subtract both sides by 49.95


49.95+0.15m-49.95=61.20-49.95

Simplify

0.15m=11.25

Now, divide both sides by 0.15


0.15m/0.15=11.25/0.15

M=75

So your answer is 75 additional minutes.


Hope this helped! Comment if you have questions!
