What value of x is in the solution set of 2(3x – 1) ≥ 4x – 6?

Leona [35]

2(3x - 1) ≥ 4x - 6 | Starting equation
6x - 2 ≥ 4x - 6 | Distribute the 2
2x - 2 ≥ -6 | Subtract 4x from each side
2x ≥ -4 | Add -2 to each side
x ≥ -2 | Divide both sides by 2

So, x must be greater or equal to -2 to be in the solution set.

The smaller triangle has a side of 16, while the corresponding side for the larger triangle is 64.

The ratio of the two sides (small to large) is 16:64 which reduces to 1:4 after we divide both parts by 16.

The ratio 1:4 basically means "multiply the smaller length by 4 to get the larger length". In other words, the larger length is 4 times longer.

----------------------------------

From here, we square both parts of the ratio above
we go from 1:4 to 1:16 after we square both parts

What does the ratio 1:16 mean? It means that the larger area is 16 times that of the smaller area

If
x = smaller area
y = larger area
then,
y = 16*x

----------------------------------

We're told that the larger area is 1360 square cm. So we know that y = 1360. Use this to find x

y = 16*x
1360 = 16*x
1360/16 = 16*x/16
85 = x
x = 85

----------------------------------

Answer: The smaller area is 85 square cm
Answer is choice D

Darina [25.2K]

Answer:

Last year Dr. Potter give<u> 32 </u>Polio vaccination and <u>28</u> measles vaccination.

Step-by-step explanation:

Given:

Each Polio vaccination consists of 4 doses , and each measles vaccination consists of 2 doses.

Last year ,Dr. Potter gave a total of 60 vaccinations that consisted of a total of 184 doses.

Now, to find the number of polio vaccinations and many measles vaccination.

Let the number of Polio vaccination be $x.$

And let the number of measles vaccination be $y.$

So, the total number of vaccinations:

$x+y=60$

$y=60-x$ .......(1)

<em>As, given each Polio vaccination consists of 4 doses , and each measles vaccination consists of 2 doses.</em>

Thus, the total number of doses:

$4x+2y=184$

Substituting the value of $y$ from equation (1):

$4x+2(60-x)=184$

$4x+120-2x=184$

$2x+120=184$

<em>Subtracting both sides by 120 we get:</em>

$2x=64$

<em>Dividing both sides by 2 we get:</em>

$x=32.$

<em>The number of Polio vaccination = 32.</em>

Now, putting the value of $x$ in equation (1):

$y=60-x$

$y=60-32$

$y=28.$

<em>The number of measles vaccination = 28.</em>

Therefore, last year Dr. Potter give 32 Polio vaccination and 28 measles vaccination.
