Solve for x: 2(10-2x) = 4(3x + 1). Write your answer as a fraction.

qwelly [4]

Answer:

$\boxed{x=1}$

Step-by-step explanation:

$2(10-2x) = 4(3x + 1)$

$\sf Expand \ brackets.$

$20 - 4x = 12x + 4$

$\sf Subtract \ 12x \ and \ 20 \ from \ both \ sides.$

$20 - 4x - 12x - 20 = 12x + 4 - 12x - 20$

$-16x = -16$

$\sf Divide \ both \ sides \ by \ -16.$

$\displaystyle \frac{-16x}{-16} =\frac{-16}{-16}$

$x=1$

Lapatulllka [165]

Answer:

0.4 , 0.1

Step-by-step explanation:

Let number of boys be = b , number of girls = b + 4 . As total students = 20 b + b + 4 = 20 → 2b + 4 = 20 → 2b = 20 - 4 = 16 → b = 16 / 2 = 8 (boys) , so girls = 12

Prob (a random first child is a boy) = boys / total students = 8 c 1 / 20 c1, or = 8 / 20 = 0.4

Prob ( a 'Tina' out of two Tina is the last) = 2 c 1 / 20 c 1 , or = 2 / 20 = 0.1
