Solve: 5/2x - 1/3= -1/2<br><br>A. x=-5/12<br>B. x= -25/12<br>C. x= -1/15<br>D. x= 1/3​
devlian [24]

Answer:

c. x = -1/15

Step-by-step explanation:

5/2x - 1/3 = -1/2 [multiply the whole equation by 6 (lowest common denom)

15x - 2 = -3 [add 2 on both sides of equation

15x = -1 [divide both sides by 15 to isolate x]

x = -1/15

Find the missing side. Round to the nearest tenth.
Firdavs [7]

Answer: <em>23.7</em>

Step-by-step explanation:

<em>Let's calculate the acute angle at the base of the triangle:</em>

<em>180° - 90° - 40° = 50°</em>

<em>Find side x:</em>

\dfrac{sin \: 90^{o} }{31} =\dfrac{sin \: 50^{o} }{x}\\\\sin \: 90^{o} \cdot x=sin \: 50^{o} \cdot 31\\\\sin \: 90^{o} =1\\sin \: 50^{o} \approx 0.766\\1 \cdot x =0.766 \cdot 31\\x=23.746\\23.746 \approx 23.7

3. The population P in thousands of a city can be modeled by the equation
madreJ [45]

Answer:

27 years

Step-by-step explanation:

P is measured in thosands therefore, P will have a value of 120

so it would be...

120=80e^0.015t

80e^0.015t=120

e^0.015t=120/80=3/2=1.5

e^0.015t=1.5

0.015t= In(1.5)

t=In(1.5)/0.015

∴ t≈27.03 round it to 27 years

It would be greatly appreciated if you gave me the brainlest
