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

First you wanna know 2 negatives equal a positive. So all you do is multiply the number 5×2=10

Answer:

area = (a + b)² = a² + 2ab + b²

Step-by-step explanation:

let side length = a + b

area of a square = side length × side length

⇒ area = (a + b)²

            = (a + b)(a + b)

            = a² + ab + ab + b²

            = a² + 2ab + b²

The fully expanded expression for the area of a square with sides of length a + b is a² + 2ab + b².

The area of a square is given by the formula: Area = side × side.

In this case, the side of the square is a + b.

Therefore, the expression for the area of the square is:

Area = (a + b) × (a + b).

To fully expand this expression using the distributive property, we'll apply the FOIL method (First, Outer, Inner, Last):

Area = a(a + b) + b(a + b)

= a² + ab + ab + b²

= a² + 2ab + b².

So, the fully expanded expression for the area of a square with sides of length a + b is a² + 2ab + b².

Answer:

You multiply the denominator and the whole number then add the numerator.

Step-by-step explanation:

Example: [tex]3\frac{2}{4}[/tex]

You multiply 3 and 4

3*4=12

Then add the numerator

12+2=14

The final answer would be

[tex]\frac{14}{4}[/tex]

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.

Answer:

17x^5 + 5x³ + 4x - 7

Degree of polynomial: 5

Step-by-step explanation:

First put the polynomial is descending order from highest exponent to lowest.

Original: 4x + 5x³ + 17x^5 - 7

New: 17x^5 + 5x³ + 4x - 7

The highest degree is 5 because that's the highest exponent. If it were m²x³ + 7x. The highest degree would be 5 because the exponents equal 5.

I hope this helps!

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

g = 5

Step-by-step explanation:

Combine like terms on the left side.

9g - g + 4g -8g = 4g

4g - 2 = 18

Add 2 to both sides.

4g = 20

Divide both sides by 4.

g = 5

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.

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
