2x + 4y = 200 ...... Ecuación 1
Hoy
Hoy compré 2 cajas más de plaquetas y otras 2 de tejas por 130 €.
2x + 2y = 130 ..... Ecuación 2
Resolvemos usando el método de Eliminación
2x + 4y = 200 ...... Ecuación 1
2x + 2y = 130 ..... Ecuación 2
Restar la ecuación 2 de 1
2 años = 70
y = 70/2
y = 35 €
Resolviendo para x
2x + 4y = 200 ...... Ecuación 1.
2x + 4 × 35 = 200
2x + 140 = 200
2x = 200 - 140
2x = 60
x = 60/2
x = 30 €
el costo de
Caja de plaquetas = x = 30 €

What is the value of x? NEDD HELP ASP
A x=15
B x=30
C x=37.5
D x=52.5
Answer:
The value of x is 15 .
Option (A) is correct.
Step-by-step explanation:
As given
∠1 and ∠2 are complementary.
i.e the sum of ∠1 and ∠2 is 90° .
Thus
∠1 + ∠2 = 90°
x° + (3x+30)° = 90°
x + 3x + 30 = 90
4x = 90-30
4x = 60
x = \frac{60}{4}x=
4
60
x = 15
Therefore the value of x is 15 .
Option (A) is correct.
Answer:
A. x=15
Step-by-step explanation:
To solve this problem, we can combine like terms.
3x + (1)x are like terms.
3x + (1)x = 4x.
Since 3x and (1)x are the only pair of like terms, we are done with this step.
Complementary angles have a sum of 90°.
4x + 30 = 90.
Next, we subtract 30 from 90.
90 - 30 = 60.
Then, we divide 60 from 4.
60 / 4 = 15.
15 is the final answer.
Therefore, the value of x is 15.

Step-by-step explanation:
1)
P = a + b + c + d
P = 7x + 8 + 7x + 8 + 9x + 4 + 12x - 2
P = 35x + 18
2)
P = 4a
P = 4(4x - 8)
P = 16x - 32
3)
P = 5a
P = 5(2x - 4)
P = 10x - 20
4)
P = 4a
P = 4(7x + 2)
P = 28x + 8
There are 8 sophomores on the academic team. At the last competition, they each took the math test. Their scores were 82%, 92%, 76%, 72%, 92%, 74%, 80%, and 78%. What was the median math score of the sophomores? 79% 82% 87% 92%
The median of the math scores is = 79%.
You can understand more about calculation of median of a set of numbers below.
Estimation of median scoresThe total number of sophomores is = 8
The percentage score of each sophomore = 82%, 92%, 76%, 72%, 92%, 74%, 80%, and 78%.
To calculate the median of the percentage scores, arrange the scores in ascending order and pick the figure in the middle as the median math score.
72, 74, 76, 78, 80, 82, 92, 92
Here the median is two figures 78, and 80 which are located in the middle. The median is =>78 +80/2
= 158/2 = 79%
Therefore, the median of the math scores is = 79%

The number of 2-digit numbers can be formed from the digits 4, 6, and 8 is 18.
What is the Permutations?Permutations are different ways of arranging objects in a definite order. It can also be expressed as the rearrangement of items in a linear order of an already ordered set. The symbol nPr is used to denote the number of permutations of n distinct objects, taken r at a time.
The given digits are 4, 6 and 8.
We know that, P(n, r)= n!/(n-r)!
Here, n=3 and r=2
Now, 3!/(3-2)!
= 3×2
= 6
Using C(n, r)= n!/r!(n-r)!
Now, 3!/2!(3-2)!
= 3
So, 6×3
= 18
Therefore, the number of 2-digit numbers can be formed from the digits 4, 6, and 8 is 18.

Step-by-step explanation:
10)
Range = Max value - Min value
18 = x - 9
x = 27
15)
Range = Max value - Min value
32 = 50 - x
-x = 32 - 50
-x = -18
x = 18
Answer:
27 and 18
Step-by-step explanation:
The range is the difference between the largest and smallest numbers

Given range = 18 and smallest number is 9 then
largest number = 9 + 18 = 27

Hey guys. So I'm doing a basic program for a battle game in Javascript, and I've having trouble on this one question. (subtraction)
If I have one number like 20, then 3 numbers such as 2, 4 and 7, I could easily find out which number in those 3 i subtracted by. For example if I had 18 as the answer, then I could do 20 - 18 and get 2 from the 3 numbers.
But how do I do that twice? or three or more after that one time? how would I know which one I picked after? (after the number is used once, it can still be used forever on, it's always random)

Step-by-step explanation:
Volume of a triangular pyramid = [tex]\frac{1}{3}(\text{Area of the triangular base})(\text{Height})[/tex]
1). Volume of the pyramid = [tex]\frac{1}{3}(72)(15)[/tex]
= 360 cm³
2). Volume of the pyramid = [tex]\frac{1}{3}(\text{Area of the triangular base})(\text{Height})[/tex]
Area of the triangular base = [tex]\frac{1}{2}(\text{Base})(\text{height})[/tex]
= [tex]\frac{1}{2}(8)(5)[/tex]
= 20 cm²
Therefore, volume of the pyramid = [tex]\frac{1}{3}(20)(12)[/tex]
= 80 cm³
5). Volume of the cone = [tex]\frac{1}{3}\pi r^{2}h[/tex]
Here, r = radius of the circular base
h = Height of the cone
Volume of the cone = [tex]\frac{1}{3}\pi (2)^2(4)[/tex]
= [tex]\frac{16\pi }{3}[/tex]
= 16.76 cm³
