Solve the following:<br> a) 4x-1 / 2= x+7<br> b)<br> 3x + 2 = 2x + 13 /3

11Alexandr11 [23.1K]

Answer:

a) 2.5

b)2.33

Step-by-step explanation:

$4x-\frac{1}{2}= x+7$

Bring the numerals to the right hand side and the x terms to the left hand side

$4x-x=7+\frac{1}{2}$

Simplify

$3x=\frac{15}{2}$

Divide 3 on both sides, to get x

$x=\frac{5}{2} =2.5$

$3x+2=2x+\frac{13}{3}$

Bring the numerals to the right hand side and the x terms to the left hand side

$3x-2x=\frac{13}{3}-2$

Simplify

$x=\frac{7}{3} =2.33$

TEA [102]

Answer:

AC = 14 cosec(68)

Explanation:

Here given:

angle: 68°

opposite: 14 ft

hypotenuse: AC

Use sine rule:

$\rightarrow \sf sin(x) = \dfrac{opposite}{hypotenuse}$

$\rightarrow \sf sin(68) = \dfrac{14}{AC}$

$\rightarrow \sf AC= \dfrac{14}{ sin(68) }$

$\rightarrow \sf AC= 14 \ cosec(68)$
