Answer:

$\sf b=2$

Step-by-step explanation:

$\sf 6(2b-4)=0$

Divide both sides by 6.

(Anything divide by zero will give you zero, and anything plus zero gives itself)

$\sf 2b - 4=0$

Add 4 to both sides.

$\sf 2b = 4$

Divide both sides by 2.

$\sf \cfrac{2b}{2}=\cfrac{4}{2}$

$\sf b = 2$

Answer:

b=2

Step-by-step explanation:

We fist of all open the brackets.

6(2b-4) =0

= 12b-24=0

Then we combine like terms

( whenever a sign crosses over an equal to sign it changes)

12b = 0+24

12b=24

Divide by co-efficient of b which is 12

12b = 24

12 12

b=2

Point a (–4,1) is in the standard ( x , y ) co ordinate pl an

ser-zykov [4K]

The line x = 2 is vertical. This means that ab is horizontal since they are perpendicular. So, the y coordinate of b must be 1.

If x = 2 bisects ab, then a and b are equal distances from x = 2.

a is 2 - (-4) = 6 units away from x = 2, so b must be 6 units away in the other direction. The x coordinate of b is 6 + 2 = 8.

The coordinate of b is (8, 1)

4,024 divided by 68 using Partial qoutients

LiRa [457]

We will use Partial quotients to find the quotient and remainder of 4024 divided by 68.

Step 1: $68 \times 50 = 3400$

Now, we will subtract 3400 from 4024,

we get remainder as 624.

Step 2: $68 \times 5 = 340$

Subtracting 340 from 624,

we get remainder as 284.

Step 3: $68 \times 4 = 272$

Subtracting 272 from 284,

we get remainder as 12.

So, Quotient = $50 + 5+ 4 = 59$ and Remainder is 12.

The Capulet and Montague families love writing. Last year, each Capulet wrote 44 essays, each Montague wrote 66 essays, and both

makvit [3.9K]

Answer: The answer is 2275 and 0.

Step-by-step explanation: Given that the Capulet and Montague families love to write. Last year, each Capulet wrote 44 essays, each Montague wrote 66 essays and both families wrote 100100 essays in total. This year, each Capulet wrote 88 essays, each Montague wrote 1212 essays, and both families wrote 200200 essays in total. We are to find the number of Capulets members and Montagues members.

Let there are 'x' members in Capulet family and 'y' members in the Montague family. Then, we have

$44x+66y=100100,\\\\88x+1212y=200200.$

Multiplying first equation by 2 and then subtracting from the second equation, we have

$1212y-132y=200200-200200\\\\\Rightarrow 1080y=0\\\\\Rightarrow y=0.$

So,

$x=\dfrac{100100}{44}=2275.$

Thus, there are 2275 Capulets and 0 Montagues.
