Answers

remember
you can do anyting to an equaiton as long as you do it to both sidess

distributive property
a(b+c)=ab+ac
commutativ property
a+b=b+a

distribute
3(4x-2)=12x-6

12x-6=9+2x+5
add 6 both sides
12x+6-6=9+6+5+2x

Divide 6/13 by 6/12 .
A. 1/12
B. 9/16
C. 12/13
D. 13/12

Answers

If you would like to divide 6/13 by 6/12, you can do this using the following steps:

6/13 / 6/12 = 6/13 * 12/6 = 12/13

The correct result would be C. 12/13.
Use the formula:

(a)/(b) /  (c)/(d) =  (a)/(b) *  (d)/(c)  = \boxed{\bf{(ad)/(bc)}}

Let's solve your question:
(6)/(13)/  (6)/(12)  =  (6)/(13) *  (12)/(6) =\boxed{\bf(12)/(13)}}

Your answer is C. 12/13.

Question 1 Which expression is the simplified form of the square root 150 times b cubed?

6 times b times the square root of 5 times b

5 times b times the square root of 6

6 times b times the square root of 5

5 times b times the square root of 6 times b

Answers

5 times b times the square root of 6 times b;
\sqrt{150* b^(3) }
\sqrt{25*6* b^(3) }
=5b√(6b)

Answer:

The simplified form of the given expression is:

       5 times b times the square root of 6 times b .

Step-by-step explanation:

We are given a expression in  words as:

     square root 150 times b cubed.

Now mathematically it is expressed as:

   √(150b^3)

Now on simplifying as follows:

√(150b^3)=√(5^2* 3* 2* b^2* b)\n\n√(150b^3)=√((5b)^2* 6b)\n\n√(150b^3)=√((5b)^2)* √(6b)\n\n√(150b^3)=5b√(6b)

Hence, we obtain the expression:

                     5 times b times the square root of 6 times b .

(i.e.  5b√(6b)   )

Which expression is the LCD of these fractions1/p^3/4/7

A p^3+7
B p+7
C 7p^3
D 7p

Answers

1/p³ ÷ 4/7 

The least common denominator of both fraction is 7p³.

Rules in dividing fractions:
1) Get the reciprocal of the 2nd fraction
1st fraction = 1/p³
2nd fraction = 4/7
reciprocal of the 2nd fraction = 7/4

2) multiply the 1st fraction with the reciprocal of the 2nd fraction

1/p³ * 4/7 = 4/7p³


Please help i cant figure this out

First work out the bracket: -1 2/3, make this into one fraction 
                                          a b/c = (ac+b)/c 
                                          ignore the negative for now, so 3+2= 5 so your                                             fraction is -5/3
Then multiply: 3/5 x -5/3 = -15/15 so your answer is -1
-1 2/3 = - (1*3+2/3)
          = - (3+2/3)
          = -5/3

Now lets multiply
= 3/5 * -5/3
= 3*-5 / 5*15
= -15/15
= -1
