Answer:

3(4x+5)=33

open the brackets(multiply both by 3)

12x+15=33

Minus 15

12x=18

x=1.5 (18/12)

Step-by-step explanation:

$3(4x + 5) = 33 \\ \\ \therefore \: 12x + 15 = 33 \\ \\ \therefore \: 12x = 33 - 15 \\ \\ \therefore \: 12x = 18 \\ \\ \therefore \:x = \frac{18}{12} \\ \\ \huge \red{ \boxed { \bold{ \therefore \:x = 1.5}}}$

Alonzo takes 12 minutes to run 6 times around a 400-meter track. Assuming he runs at a constant speed, how long does he take to

Answer:

5 minutes to run 1 kilometer

Step-by-step explanation:

Alonzo takes 12 minutes to run 6 times around a 400-meter track.

6 times around a 400 m track

400 * 6 = 2400 meters

It take 12 minutes to run 2400 meters

2400 meters = 2400/1000 = 2.4km

distance = 2.4 km and time = 12 minutes

Now we find our constant speed

$Distance = speed * time$

2.4 = speed * 12

divide by 12 on both sides

speed = 0.2

so speed is 0.2 km per minute

Now we find out time when distance = 1km

Distance = speed * time

1 = 0.2 * t

divide by 0.2 on both sides

5 = t

So it take 5 minutes to run 1 kilometer

2sin^2x - sinx - 3 = 0

e-lub [12.9K]

We have that
2sin²<span>x - sinx - 3 = 0
</span>
Let
A------> sin x
so
2A²-A-3=0

using a graph tool-----> to resolve the second order equation
see the attached figure

the solutions are
A=-1
A=1.5------> is not solution because sin x <span>can not be 1.5

the solution is
A=-1
therefore
sin x=-1
x=arc sin(-1)=-90</span>°

the answer is
sin x=-1
x=-90° or 270°
