Simplify the following surd expressions<br> a) 7/3 - 2/3 + V3 - 3V3

Nata [24]

Answer:

$\frac{7}{3}-\frac{2}{3}+\sqrt{3}-3\sqrt{3}=\frac{5}{3}-2\sqrt{3}$

Step-by-step explanation:

Given the expression

$\frac{7}{3}\:-\:\frac{2}{3}\:+\:v^3\:-\:3v^3$

solving the expression

$\frac{7}{3}\:-\:\frac{2}{3}\:+\:\sqrt{3}-3\sqrt{3}$

combine the fractions i.e $\frac{7}{3}-\frac{2}{3}=\frac{5}{3}$

$\frac{7}{3}\:-\:\frac{2}{3}\:+\:\sqrt{3}-3\sqrt{3}=\frac{5}{3}+\sqrt{3}-3\sqrt{3}$

add similar elements i.e $\sqrt{3}-3\sqrt{3}=-2\sqrt{3}$

$=\frac{5}{3}-2\sqrt{3}$

Thus,

$\frac{7}{3}-\frac{2}{3}+\sqrt{3}-3\sqrt{3}=\frac{5}{3}-2\sqrt{3}$

Solve the following proportion4 x— = —7 28x=

Ierofanga [76]

Answer:

x = 16

Explanations:

The given rquation is:

$\frac{4}{7}=\text{ }\frac{x}{28}$

Step 1: Cross multiply the equations. That is 28 multiplies 4 and 7 multiplies x:

$28\text{ x 4 = 7 }\times\text{ x}$ 112 = 7x

Step 2: Divide both sides by 7

$\frac{112}{7}=\text{ }\frac{7x}{7}$ 16 = x x = 16
