3/4+x=2x−x+_
Make equation have infinite solutions in the blank

Answers

Answer:

3/4

Step-by-step explanation:

3/4+x=2x−x+_

2x-x is x

So the equation is now

3/4+x=x+_

So to have infinite solutions, we will have to get both of the sides the same value

Since there is already an x on both sides we don't have to worry about it

Now there isn't a 3/4 on one side so we can just add that to the blank side, thus creating an infinite solution equation

Hope this helps!

B+8/2=6
How do I do this

Answers

divide 8/2 which is 4 so B+4=6 subtract 4 from both sides so b+4-4=6-4

so that means B=2 and that is ur answer

Answer:

B = 2.

Step-by-step explanation:

First work out 8/2. Okay so how many 2's go into 8? 4.

We now have B + 4 = 6.

Now that we've simplified it a bit we can do a reverse equation and turn it into subtraction.

Take the answer (6) and 4 and put them into a subtraction equation,

6 - 4. And simple subtraction should be easy so 6 - 4 = 2.

So B equals 2. Let's check it! 2 + 4 = 6. I think that sounds right so that will be the answer. B=2.

Hope that helps. x

Solve for x:
4x-3Divided by 2 =5/3

Answers

Answer:

x=19/12

Step-by-step explanation:

(4x-3)/2 = 5/3

4x-3 = 10/3

3 = 9/3

4x = 10/3 + 9/3 = 19/3

x = 19/12

Hey there!

4x - 3/2 = 5/3

ADD 3/2 to BOTH SIDES

4x - 3/2 + 3/2 = 5/3 + 3/2

CANCEL out: -3/2 + 3/2 because it gives you 1

KEEP: 5/3 + 3/2 because it helps solve for the x-value.

NEW EQUATION: 4x = 5/3 + 3/2

SIMPLIFY IT!

4x = 19/6

DIVIDE 4 to BOTH SIDES

4x ÷ 4 = 19/6 ÷ 4

CANCEL out: 4 ÷ 4 because it gives you 1

KEEP: 19/6 ÷ 4 because it helps solve for the x-value

NEW EQUATION: x = 19/6 ÷ 4

SIMPLIFY IT!

x = 19/24

There are eight swans swimming on a pond and four of those swans are
black. What fraction of the swans are black?

Answers

Answer: A. (4/8)

Step-by-step explanation: If there is 4 black swans and 8 swans in total you could see it's 4 black swan out of 8 total swans. You could do

8/8 - 4/8 = 4/8 to find out the answer too.

Total number of swans= 8
Total no.of black swans= 4
Fraction of black swans among all swans= 4/8
If you simplify 4/8 you will get 1/2, in exam you have to always write the simplified version to get full marks
