3x - 2y= 5, 4x + 3y= 1​

Answer:

6

Step-by-step explanation:

3n=3(n)

ur replcing n with 2

3(2)=3x2

3x2=6

Answer:

6

Step-by-step explanation:

3n means you are multiplying 3 and n. since n = 2, the only thing you need to do is plug in 2 for n and then simplify by multiplying 3 · 2.

plug in 2 for n:

3n ⇒ 3(2)

multiply 3(2):

3(2) = 6

therefore, when n = 2, 3n = 6.

Answer:

B. y=50x

Step-by-step explanation:

We can see the y intercept is 0 because the line starts at 0.

To find the slope, we can look at the first point. It is at (1, 50).

Slope=rise/run or change in y/change in x=50/1=50.

Given:

Base of smaller figure = 20 cm

Area of smaller figure = 320 cm²

Base of the larger figure = 25 cm

To find:

The area of the larger figure.

Solution:

We know that the areas of the similar figure are proportional to the square of corresponding sides of them.

Let A be the area of the larger figure.

[tex]\dfrac{\text{Area of the larger figure}}{\text{Area of the smaller figure}}=\dfrac{(\text{Base of the larger figure})^2}{(\text{Base of the smaller figure})^2}[/tex]

[tex]\dfrac{A}{320}=\dfrac{(25)^2}{(20)^2}[/tex]

[tex]\dfrac{A}{320}=\dfrac{625}{400}[/tex]

[tex]\dfrac{A}{320}=\dfrac{25}{16}[/tex]

Multiply both sides by 320.

[tex]A=\dfrac{25}{16}\times 320[/tex]

[tex]A=500[/tex]

Therefore, the area of the larger figure is 500 cm².

Answer:

Step-by-step explanation:

Volume = Area of the base times the height

V = length * width * height

V = 10 * 5 * 1

V = 50 m^3

Now change it to liters

50 * 1000 = 50000 liters^3

Answer:

the total cost is $1,495,000

Step-by-step explanation:

The computation of the total cost is shown below:

Let us assume the months be m

Now the equation would be

= Equipment + software + wages

= $840,000 + $15,000 + 40,000m

= $840,000 + $15,000 + $40,000 (16)

= $840,000 + $15,000 + $640,000

= $1,495,000

Hence, the total cost is $1,495,000

Answer: Choice A) There must be a vertical asymptote at x = c

Explanation:

The first limit [tex]\displaystyle \lim_{x\to c^{-}}h(x) = -\infty[/tex] says that as x approaches c from the left side, the f(x) or y values approach negative infinity. So the graph goes down forever as x approaches this c value from the left side.

The limit [tex]\displaystyle \lim_{x\to c^{+}}h(x) = \infty[/tex] means that as x approaches c from the right side, the y values head off to positive infinity.

Either of these facts are enough to conclude that we have a vertical asymptote at x = c. We can think of it like an electric fence in which we can get closer to, but not actually touch it.

Given:

Total solution : 1000mL

Pure acetic acid = 26mL

To find:

The percent concentration of given solution.

Solution:

We know that,

[tex]\text{Percent concentration}=\dfrac{\text{Pure acetic acid}}{\text{Total solution}}\times 100[/tex]

Putting the given values, we get

[tex]\text{Percent concentration}=\dfrac{26}{1000}\times 100[/tex]

[tex]\text{Percent concentration}=\dfrac{26}{10}[/tex]

[tex]\text{Percent concentration}=2.6[/tex]

Therefore, the percent concentration of this solution is 2.6%.

Answer:

50% chance

Step-by-step explanation:

The even numbers on a die are 2, 4 and 6 compared to the odd numbers 1, 3 and 5. This is 3/6 of the numbers which is 1/2 when simplified. 1/2 is equal to 50%

Answer:

3m•sen(60°) es la respuesta

Answer:

4/5

Step-by-step explanation:

sine is opposite over hypotenuse,

so it's 40/50=4/5

Answer:

12 pens

Step-by-step explanation:

Let the variable that can be used to determine the number of pens that Kamila bought be represented by n.

Price of a notebook = $1.59

Price a pen = $0.29

Total amount spent = $5.07

But,

1.59 + 0.29 n = 5.07

So that,

0.29 n = 5.07 - 1.59

0.29 n  = 3.48

n = [tex]\frac{3.48}{0.29}[/tex]

  = 12

Therefore, Kamila bought 12 pens.

Answer:

Step-by-step explanation:

i took the test and got 100

Answer:

15. percent *80 =

(15.:100)*80 =

(15.*80):100 =

1200:100 = 12

Now we have: 15. percent of 80 = 12

Percentage solution with steps:

Step 1: Our output value is 80.

Step 2: We represent the unknown value with

Step 3: From step 1 above

Step 4: Similarly

Step 5: This results in a pair of simple equations:

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

Step 7: Again, the reciprocal of both sides gives

Answer:

El camino diagonal debe medir 100 metros de largo.

Step-by-step explanation:

Podemos encontrar el camino usando Pitágoras:

[tex] D^{2} = L^{2} + A^{2} [/tex]

En donde:        

D: es el camino diagonal = hipotenusa

L: es el largo = 80 m = cateto

A: es el ancho = 60 m = cateto

Entonces, el camino diagonal es:

[tex] D = \sqrt{L^{2} + A^{2}} = \sqrt{(80 m)^{2} + (60 m)^{2}} = 100 m [/tex]

Por lo tanto, el camino diagonal debe medir 100 metros de largo.

Answer:

MN = π

Step-by-step explanation:

The arc MN is calculated as

MN = circumference of circle × fraction of circle

      = 2πr × [tex]\frac{60}{360}[/tex] ( r is the radius )

      = 2π × 3 × [tex]\frac{1}{6}[/tex]

     = 6π × [tex]\frac{1}{6}[/tex]

     = π

Answer:

243 inches

Step-by-step explanation:

27 bracelets at 9inches each

9x27=243 inches or 20 feet and 1/4 inches of string. Depending on how the string is sold (by the foot, by the inch, yard, etc) will determine her minimum quantity, if you want to get specific.
