Answer:

$x = \frac{15}{8}$

$\\$

Step-by-step explanation:

$\frac{10}{14} = \frac{x}{2x - 3 + x} \\ \frac{10}{14} = \frac{x}{3x - 3} \\ 10(3x - 3) = 14x \\ 30x - 30 = 14x \\ 30x - 14x = 30 \\ 16x = 30 \\ x = \frac{30}{16} \\ x = \frac{15}{8}$

A bag holds 1 blue block and 3 yellow blocks. How many green blocks should be added to the bag to make the probability of random

Drupady [299]

$n$ - the number of green blocks which is equal to the number of favourable events
$1+3+n=4n$ - the number of all blocks, which is equal to the number of all possible outcomes

$P(A)=\dfrac{n}{4+n}=\dfrac{1}{2}\\
1\cdot( 4+n)=2\cdot n\\
4+n=2n\\
2n-n=4\\
n=4
