Answer:

D) no solution

Step-by-step explanation:

2x - 4y = 14

X + 2y = 7

2x - 4y + x + 2y = 14 + 7

2x - 4y + x + 2y = 21

3x - 2y = 21

no solution

Answer:

x=2y+7

step by step explanation:

2x-4y=14

2(x-2y)=14

x-2y=14/2

x-2y=7

x=2y+7

Step-by-step explanation:

We know that for a square of side length s, the perimeter is given by:

P(s) = 4*s

a) If initially we have s = 1cm, then the initial perimeter is:

P(1cm) = 4*1cm = 4cm

if now s changes to 1.5cm, the new perimeter will be:

p(1.5cm) = 4*1.5cm = 6cm

So the side length increased 0.5cm, and the perimeter increased 4 times that, 2cm.

b) We can define the change in side length as Δs, then if the initial side length is s, the new side length will be written as:

s + Δs

using this in the perimeter equation we get:

P(s + Δs) = 4*(s + Δs) = 4*s + 4*Δs = P(s) + ΔP

We can see that ΔP = 4*Δs

c) We already know the formula, it is P(s) = 4*s, the graph can be seen below.

d) We need to solve 8 = 4*s

To get this, we need to isolate s.

s = 8/4 = 2

s = 2

This means that if the perimeter is 8cm, then the side length must be 2cm

e) P = 4*s

is the perimeter in terms of the side length, we want to get the side length in terms of the perimeter, we just need to divide both sides by 4:

s = P/4

f) The formula we got in (e) is the formula P = 4*s divided on both sides by 4.

That is the relation between the two formulas.

El tamaño del paso se puede determinar mediante progresión aritmética.

Para determinar el tamaño del paso, usamos lógica aritmética de prorrateo.

Del formulario de progresión aritmética, donde:

[tex] a_{n} \: = a \: + \: (n - 1)d[/tex]

n = número de términos (número de pasos) = 9

d = diferencia común (tamaño de los pasos)

[tex] a_{n}[/tex]

Valor del enésimo término = 2

a = primer término = 1

Usando los parámetros, podemos obtener el valor de d que es el tamaño de cada paso.

Ingresando los valores en la fórmula:

2 = 1 + (9 - 1) d

2 = 1 + 8d

2 - 1 = 8d

1 = 8d

d = 1/8

d = 0,125

Por tanto, el tamaño del paso es de 0,125 metros.

Step-by-step explanation:

4000 Watts means that if you run the machine for one hour, you are using 4000 watt-hours or more commonly used 4 kWh (kilo means 1000).

for 14 cents per kWh we have then

14 × 4 = 56 cents per day

now, if the other model uses only 2000 Watts and still only needs 1 hour for the same job (which is in reality NOT a given, very often such a machine means that it will have to run close to 2 hours) it would cost

14 × 2 = 28 cents per day, saving 28 cents per day.

for a year running the dryer daily

we would save

28 × 365 = 10220 cents = $102.20 savings per year

Answer:

18

Step-by-step explanation:

They want u to find MR, and I can do that by taking CR - CM

But first we need to know what is x

Now u know CM + MR =CR

Therefore

(3x - 2) + (x+8) = 46

3x - 2 + x + 8 = 46

4x + 6 = 46

4x = 40

x = 10

Now we know x is 10, let's just make it easier first

CM = 3x-2

= 3 (10) - 2

= 28

MR = x + 8

= 10 + 8

= 18

Now we got all our values

They want MR?

MR = x + 8

= 10 + 8

= 18

HERE U GO

Answer:

18

Step-by-step explanation:

cm=3x -2

mr=x +8

cr=46

cm+mr=cr

3x-2+x+8=46

4x+6=46

4x=46-6

x=40/4

x=10

hence, mr=x+8

=10+8

=18

Answer:

   [[. . 3 6 .][1 3 4 9 .][9 2 . 7 1][. 1 2 8 3][. 4 9 . . ]]

Step-by-step explanation:

It is helpful to remember that the first four digits {1, 2, 3, 4} total 10, and the last four digits {6, 7, 8, 9} total 30. It is also worthwhile to note that the smallest sum of two digits is 3 = 1+2, and the largest sum of 2 digits is 17 = 8+9. Some sums can only be made one way: 4 = 1+3, 16 = 7+9.

Here, we will refer to rows 1-5 from the top down, and columns 1-5 from the left to right.

__

Based on the above, column 5 can only be made one way: 1+3. Column 4 can only be made one way: 9+8+7+6. Then the choices for row 3B will be 1+7 or 5+3. We know it can't be 5+3 because 5 is not part of column 4. This makes our first fill-in (row, column) be (3,4)=7, (3,5)=1, (4,5)=3.

The sum of the remaining cells in row 4 must be 14-3 = 11, and cell (4,4) must be 6, 8, or 9. It cannot be 9, because that would require the remaining two cells to have a sum of 2, which they cannot. So, cell (4,4) is 6 or 8.

Cell (1,4) cannot be 9, either, because we cannot use 0 in cell (1,3). Then the only place for 9 in column 4 is in cell (2,4)=9.

With cell (1,4) being restricted to 6 or 8 (the two remaining numbers in column 4, cell (1,3) must be 3 or 1, and cell (2,3) must be 4 or 6. It cannot be 6 because that would require a sum of 2 in the first two cells of row 2, so (2,3)=4, (1,3)=3, and (1,4)=6. This makes (4,4)=8 and the remaining two cells of row 4 must be 1 and 2. 1 cannot go in (4,3), so we must have (4,3)=2 and (5,3)=9, (5,2)=4, (4,2)=1. That leaves 2 and 3 for rows 2 and 3 of column 2. The first two cells of row 2 must total 4, so must be 1 and 3. Cell (2,2) cannot be 1, so must be 3, leaving (2,1)=1, (3,1)=9, (3,2)=2 and that completes it.

The fill-ins are ...

   [. . 3 6 .]

  [1 3 4 9 .]

  [9 2 . 7 1]

  [. 1 2 8 3]

  [. 4 9 . . ]
