Answer:

Step-by-step explanation:

Hello,

You need to group the terms in x

$-2 \times x + \times x = (-2+5) \times x = 3 x$

And then, you can divide by 3 to find the solution

$-2x+5x=3x=9x=9/3=3$

Hope this helps

Answer:

The Right Equivalent Fraction for the give Fractions are,

$\dfrac{1}{2}$ ------------------> $\dfrac{6}{12}$

$\dfrac{6}{8}$ ------------------> $\dfrac{3}{4}$

$\dfrac{4}{5}$ ------------------> $\dfrac{8}{10}$

$\dfrac{2}{3}$ ------------------> $\dfrac{8}{12}$

$\dfrac{10}{12}$ ------------------> $\dfrac{5}{6}$

Step-by-step explanation:

The Right Equivalent Fraction for the give Fractions are,

$\dfrac{1}{2}$ -------------> $\dfrac{6}{12}=\dfrac{6}{6\times 2}$

$\dfrac{6}{8}=\dfrac{2\times 3}{2\times 4}$ ---------------> $\dfrac{3}{4}$

$\dfrac{4}{5}$ ------------------> $\dfrac{8}{10}=\dfrac{2\times 4}{2\times 5}$

$\dfrac{2}{3}$ ------------------> $\dfrac{8}{12}=\dfrac{4\times 2}{4\times 3}$

$\dfrac{10}{12}=\dfrac{2\times 5}{2\times 6}$ ------------------> $\dfrac{5}{6}$

The Right Equivalent Fraction for the give Fractions are,

$\dfrac{1}{2}$ ------------------> $\dfrac{6}{12}$

$\dfrac{6}{8}$ ------------------> $\dfrac{3}{4}$

$\dfrac{4}{5}$ ------------------> $\dfrac{8}{10}$

$\dfrac{2}{3}$ ------------------> $\dfrac{8}{12}$

$\dfrac{10}{12}$ ------------------> $\dfrac{5}{6}$

There are 7 balls in the bag: 3 blue, 2 red and 2 white. What is the probability that one would pick two balls of the same colou

bearhunter [10]

Answer:

5/21.

Step-by-step explanation:

Total number of balls = 7.

Prob(Blue on first pick) = 3/7

Prob(Blue on second pick) = 2/6 = 1/3

So Prob( 2 Blue's) = 3/7 * 1/3 = 3/21 = 1/7.

Prob(Red on first pick) = 2/7

Prob(Red on second pick) = 1/6

So Prob( 2 Red's) = 2/7 * 1/6 = 1/21.

Now the Probability of getting 2 white balls is the same as for the red balls

= 1/21.

Finally, the probability of 2 balls of the same colour

= 1/7 + 1/21 + 1/21

= 3/21 + 1/21 + 1/21

= 5/21.
