Hope this picture helps!

The 2.7 has been broken into 2 and 0.7, and then both of these parts have been multiplied by 3, giving you the two answers of 6 and 2.1 shown. Adding these two together gives you the answer of 8.1.

How do you multiply 12x12 step by step?

geniusboy [140]

Answer:

144

Step-by-step explanation:

X12

------

If you are writing this problem out by hand, be sure that your numbers are lined up, like above. This will help you in making sure that you solve each step of your problem properly.

First, start with the 12. Multiply 12 by the "2" in the one's place, in the second number:

X 2

-----

Begin by multiplying 2 X 2 first, in the "ones" column.

Do you have 2X2=4? Great! Put the 4 in the ones column, where your answer would go.

Next, multiply 2 times the 1 digit. The 1 is actually a 10, because it is in the "tens" column.

2 X10=20

Place your 2 in the "tens" column--It should look like this...

X 2

-----

Since you are finished with the "ones" place, now you will work with the tens column.

put a zero under the 4 in 24.

then continue like this

X12

-----

120 because 12 X10=120

------

144 If you add 24 +120, you should have 144.

If you have a slightly different way of doing this problem, that's OK. The point is to get the correct answer.

If you have a times table, you can check yourself.

12 X12=144

Tony and Maria are two star-crossed lovers trying to get on a committee of 4 people. If there are 9 people eligible for this com

ASHA 777 [7]

Answer:

The number of ways Tony and Maria can both be selected for the committee is 8 ways.

Step-by-step explanation:

i) Tony and Maria have to be on the committee together or not at all.

ii) Let us consider Tony and Maria as combined as one person.

Therefore now we can say that the number of eligible people for the committee = 9 - 1 = 8.

iii) therefore the number of ways that both Tony and Maria can be selected for the committee are

= 8C1 = $\hspace{0.2cm}\binom{8}{1} = \frac{8!}{1! (8-1)!} = \frac{8!}{1!\times 7!} = \frac{8}{1} = \hspace{0.1cm}8 \hspace{0.1cm}ways$

Find the least common denominator of 7 and X+4 x-4

Effectus [21]

(X+4)(X-4) is the LCD because you just have to look at the denominators and see what factors or values are not already part of your LCD.
