Answer:

Step-by-step explanation:

since you gave no values for both T and S, this is impossible to solve.

figure out what the difference is between the 2 numbers of T and S, then divide that by 200. that should give you the answer.

Answer:

71

Step-by-step explanation:

I think because it's not at 70 and it's not at 80 so 71 because it's between 70 and 80

Usando algebra, veremos que cada estudiante debe aportar $5.00.

En el caso en el que hay 25 estudiantes, cada uno aporta $4.00, entonces la cantidad total que se colecta es:

25*$4.00 = $100

Ahora, en el caso de que hay 20 estudiantes, cada uno aportara una cantidad x, de tal forma que:

20*x = $100

Debemos resolver la ecuación de arriba para x:

x = $100/20 = $5.00

Es decir cada estudiante debe aportar $5.00

Answer:  y = (1/3)x - 5

This is the same as writing [tex]y = \frac{1}{3}x-5[/tex]

======================================================

Explanation:

Assume we have a linear pattern matching the form y = mx+b.

The first row has x = 12 lead to y = -1

The second row has x = 3 lead to y = -4

This produces the two points (12,-1) and (3,-4)

Let's find the slope through those points.

m = (y2-y1)/(x2-x1)

m = (-4-(-1))/(3-12)

m = (-4+1)/(3-12)

m = -3/(-9)

m = 1/3

The slope is 1/3.

The y intercept is b = -5 since x = 0 leads to y = -5

We go from y = mx+b to y = (1/3)x - 5

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

To verify we have the correct equation, plug in each left side value as x values.

Let's try x = 12

y = (1/3)x - 5

y = (1/3)*12 - 5

y = 4 - 5

y = -1

This shows that the input x = 12 maps to the output y = -1

i.e.  12 ↦ −1 is the case here.

Repeat for x = 3

y = (1/3)x - 5

y = (1/3)*3 - 5

y = 1 - 5

y = -4

We can see that 3 ↦ −4 occurs.

I'll let you check the others, but you should find that the other mappings hold true as well. Therefore, the answer has been fully confirmed.

Answer:

2

Step-by-step explanation:

[tex]x + 17 = - 2x + 23 \\ \\ x + 2x = 23 - 17 \\ \\ 3x = 6 \\ \\ x = \frac{6}{3} \\ \\ x = 2[/tex]

Answer:

x = 2

Step-by-step explanation:

First, we will move all the xs to one side and everything else to the other side.

x + 17 = -2x + 23

+2x       +2x

-17         -17

This gives us:

x + 2x = 23-17

Then we can just combine like terms:

3x = 6

And divide both sides by three:

x = 2

The room's width should remain unchanged at 300 inches.

If the question is asking room of the same area but length shortened to 10 inches, then the answer is 400*300/`10 = 12000 inches.

One thing the question lacking (The area of both room is same).

Answer:

1 kg, 0.8 kg, 1.6 kg

Step-by-step explanation:

Add up each part in the ratio

5 + 4 + 8 = 17

Divide the mass of the alloy by 17

3.4/17 = 0.2

To find out how much of each metal is in the alloy multiply 0.2kg by how many parts of it are in the alloy.

Nickel - 5 parts

0.2 x 5 = 1 kg

Zinc - 4 parts

0.2 x 4 = 0.8 kg

Copper - 8 parts

0.2 x 8 = 1.6 kg

Answer:

Step-by-step explanation:

5x+4x+8x=3.4

17x=3.4

x=0.2

Nickel 1 kg

Zinc 0.8 kg

Copper 1.6 kg

Hey there!

Please remember that the ordered pair (0,0) is also called the origin.

Its x-coordinate is 0, and its y-coordinate is 0.

If a line intersects a point (0, 0) then it basically intersects the origin.

Hope everything is clear.
