Solve for x 3x+4 = (2/5)x +2

julsineya [31]

Answer:-10/13

Step-by-step explanation:

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

First move the 4 to the other side by subtracting it.

it becomes : 3x = (2/5)x - 2

then multiply everything by 5 to get rid of the fraction.

it becomes 15x = 2x -10

then move the 2x to the other side by subtracting it.

you get 13x = -10

now you can divide everything by 13 to isolate the x.

and you get x = -10/13

Brad the pair of fractions as a pair of fractions with a common denominator 3/10 and 1/2

LuckyWell [14K]

Answer:

2/10 and 3/10

Step-by-step explanation:

Hello!

The best way of finding common denominators is using their factors!

(of denominators)

10 : 1, 2, 5, 10

2 : 1, 2

We also can see that 10 is divisible by 2.

For that reason, 1/2 is equivalent to 2 * 10 ÷ 2.

That's 10.

So 5/10 and 3/10 have a common denominator 10.

Hope this helps!

what is the answer to the multiplication problem. Jhon has 20 fish if he lets 6 fish go how many fish dose Jhon have?

spayn [35]

Isn't this a subtraction problem, not a multiplication problem?

If John starts out with 20 fish and lets 6 go, he still has (20-6), or 14, fish.
