In your own words explain how you would solve this two step equation for the variable x. 9x-7=-7

Answers

Answer 1

Answer:

Add 7 to both sides

Step-by-step explanation:

The equation has to be just x = y

There cannot be another number on the same side as the variable

Now that we did that, the equation is 9x = 0

x = 0

Well, that was easy lol

Answer 2

Answer:

Step-by-step explanation:

Add 7 to both sides

9x = 0

Then divide by 9 both sides to get x by itself

x = 0

Marks

Sarah:

Robert

Answers

Answer:

James = 119 points

Sarah = 357 points

Roberts = 51 points

Step-by-step explanation:

Given that :

James = x points

Sarah = 3x points

Roberts = x - 68 points

Each point = 3 pence

All students have a total of £15.81

1 pound = 100 pence

£15.81 pound = 1581 pence

3x + 3(3x) + 3(x - 68) = 1581

3x + 9x + 3x - 204 = 1581

15x - 204 = 1581

15x = 1581 + 204

15x = 1785

x = 1785 / 15

x = 119

Hence,

James = 119 points

Sarah = 119 * 3 = 357 points

Roberts = 119 - 68 = 51 points

Eli is following this recipe to bake bread rolls.
He uses 700 mL of water.
How much of the other ingredients does he use?

Recipe: Makes 12 bread rolls
420 g flour
21 g salt
9 g yeast
45 mL oil
300 mL water

Answers

400/300 = 4/3 the water listed in the recipe
420g × 4/3 = 560g flour
21g × 4/3 = 28g salt
9g × 4/3 = 12g yeast
45ml × 4/3 = 60ml oil

En un día de febrero, una ciudad de Estados Unidos registró una temperatura mínima de 9° bajo cero y una temperatura máxima de 13°C. ¿De cuántos grados fue el intervalo de temperaturas registradas?

Answers

Answer:

La cantidad de grados del intervalo de temperaturas registradas en el día de febrero mencionado es de:

5

Step-by-step explanation:

En estadística, cuando se utilizan intervalos como valores para identificar datos cuantitativos, como en este caso temperaturas registradas, deben tomarse todos los valores, en este caso enteros, desde el límite inferior (temperatura mínima) hasta el límite superior (temperatura máxima), por lo cual no se puede restar el valor máximo al valor mínimo, sino que debes identificar todos los valores y después contarlos. En el caso del ejercicio dado, los grados en el intervalo mencionado son:

9°C10°C11°C12°C13°C

Como puedes ver, los grados en el intervalo de temperaturas registradas serían 5.

Ir (2p-1,p) is a solution of the equation 9y + 12 = 10x, then find the value of p​

Answers

Answer:

p = 2

Step-by-step explanation:

Since, (2p-1,p) is a solution of the equation 9y + 12 = 10x.

Therefore, plug x = 2p - 1 & y = p in the above equation.

9p + 12 = 10(2p - 1)

9p + 12 = 20p - 10

12 + 10 = 20p - 9p

22 = 11p

p = 22/11

p = 2

What is division?

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

Simone is buying pies for a party.

One cherry pie costs $7,

and one apple pie costs $5.

If Simone needs to buy at least 18 pies and has no more than $110 to spend,

the maximum number of cherry pies,

= 15.71.

If 15 cherry pies, then 3 apple pies.

The total amount = 15 x 7 + 3 x 5

= 110

Therefore, 15 is the maximum number.

This is a question worth knowing how to do. It is prime candidate for a test question.

Equation

Let the unit be x

therefore

4x + 5x + 6x = 45

Solution

15x = 45

x = 45/15

x = 3

The shortest piece is 4*3 = 12

The middle piece = 5*3   = 15

The longest piece = 6*3 = 18

Total                                    45
