What is the solution to the equation 8-2b= -2/3(12b+6) ?

b =??????????????

Answers

ok so remember you can do anything to an equaiton as long as you do it to both sides

-8-2b=-2/3(12b+6)
distribute so we can work with innter terms
a(b+c)=ab+ac
-2/3(12b+6)=-24b/3-12/3=-8b-4

we now have
8-2b=-8b-4
get all b's on one side
add 8b to both sides
8+8b-2b=8b-8b-4
8+6b=0-4
8+6b=-4
subtract 8 fro both sides
8-8+6b=-4-8
0+6b=-12
6b=-12
divide both sides by 6
6/6b=-12/6
1b=-2
b=-2



b=-2
So the answer would be b=-2. The steps of this is you would refine -2/3 (12b+6) to -4(2b+1) so then the equation would turn into 8-2b= -4 (2b+1). Then you would expand -4(2b+1) into -8b+4. So now the equation is 8-2b=-8b-4. Then you'd subtract 8 from both sides: 8-2b-8=-8b-4-8 which is -2b=-8b-12. Then you'd add 8b to each side. -2b+8b=-8b-12+8b that equals 6b=-12. Then you divide both sides by 6: 6b/6=-12/6. Then you get b= -2. Hope this helped. 

Determine the quotient of 3/5 and 2/3

Answers

The quotient of 3/5 and 2/3 is 9/10 and this can be determined by using the arithmetic operations.

Given :

Number 1 - 3/5

Number 2 - 2/3

The following steps can be used to determined the quotient of 3/5 and 2/3:

Step 1 - First, divide 3/5 by 2/3.

=((3)/(5))/((2)/(3))

Step 2 - Now, multiply 3/5 and 3/2.

=(3)/(5)* (3)/(2)

Step 3 - Multiply 3 and 3 in the above expression.

=(9)/(5* 2)

Step 4 - Multiply 5 and 2 in the above expression.

=(9)/(10)

The quotient of 3/5 and 2/3 is 9/10 and this can be determined by using the arithmetic operations.

Answer:

The result is (9)/(10)

Step-by-step explanation:

Below are the steps to divide fractions:

  1. The 1st fraction remains untouched.
  2. The division sign turns into a multiplication sign.
  3. Flip the 2nd fraction over (finding its reciprocal)
  4. Multiply the numerators (top numbers) together
  5. Multiply the denominators (bottom numbers) together.
  6. Simplify the resulting fraction by dividing both numerator and denominator by the same number.

Let's follow the above steps:

Steps 1, 2 and 3 can be done together.

(3)/(5):(2)/(3) = (3)/(5).(3)/(2)

As you can see, we leave 1st fraction alone, change division sign (:) by multiplication sign (.), and flip 2nd fraction over.

Now, we can do steps 4 and 5...

(3)/(5):(2)/(3) = (3)/(5).(3)/(2) = (3.3)/(5.2) = (9)/(10)

Finally, step 6, we cannot simplify the resulting fraction since both numerator and denominator have no common factors.

9 = 3 . 3

10 = 2 . 5

T is to 9 as 7 is to 39

Answers

Answer:

T = 21/13

Step-by-step explanation:

Step 1:  Make an expression

T is to 9 as 7 is to 39

(T)/(9) = (7)/(39)

Step 2:  Cross multiply

(T)/(9) = (7)/(39)

39(T) = 7(9)

39t = 63

Step 3:  Divide both sides by 39

39T / 39 = 63 / 39

T = 21 / 13

Answer:  T = 21/13

Which equation best represents this situation? The number 46 is equal to 23 multiplied by an unknown number.



A.


46 = 23 ÷ p


B.


46 = 23p


C.


46 = 23 – p


D.


46 = 23 + p
NEED help plz!

Answers

So since the problem says the number 46 is equal to something, you immediately know that your equation will look like this

46 = something

Now, when an unknown number is multiplied by a number, it has the number and a letter right next to it.

example.  23p

So since 23p = 46, your answer is B :) Hope this helped!
it's B because p is used as the unknown number here and some ways of saying multiplication is
23 x p
23 (dot in the middle) p
or 23p
since the qw says the number 46 is equal to it is
46=
so the answer is B) 46=23p
