Multiply total students by 2/3 to find how many like math:

Like math = 120 x 2/3 = 240/3 = 80 total students like math

Multiply total students by 3/5 to find number of boys:

120 x 3/5 = 360/5 = 72 boys

A) number of girls = total students - boys = 120 -72 = 48 girls

Solve the expression and find the value of x.

vovangra [49]

$\large\underline{\sf{Solution-}}$

$\sf \dfrac{x + 1}{10} - \dfrac{3(x - 1)}{5} = 2$

$\sf\longmapsto \dfrac{x + 1}{10} - \dfrac{3x - 3}{5} = 2$

$\sf\longmapsto \dfrac{(x + 1) - 2(3x - 3)}{10} = 2$

$\sf\longmapsto \dfrac{x + 1 - (6x - 6)}{10} = 2$

$\sf\longmapsto \dfrac{x + 1 - 6x + 6}{10} = 2$

$\sf\longmapsto \dfrac{ - 5x + 7}{10} = 2$

$\sf\longmapsto - 5x + 7 = 20$

$\sf\longmapsto - 5x = 20 - 7$

$\sf\longmapsto - 5x = 13$

$\sf\therefore x = - \dfrac{13}{5}$

Hence, the value of x will be -13/5 respectively.

Black: 0

Blue: 2/5 or 0.4 or 40%

Step-by-step explanation:

In total, the bag contains 10 balls,

2 are Red = 2/10 = 1/5
