What is the value of x in the equation 2.5(6x - 4) = 10 + 4(1.5 +0.5 x)?

0 13

Answers

Answer:

Step-by-step explanation:

15x - 10 = 10 + 6 + 2x

15x - 10 = 16 + 2x

Bringing like terms on one side

15x - 2x = 16 + 10

13x = 26

x = 26/13

x = 2

The value of x in the equation is 2.

Option C is the correct answer.

What is an equation?

An equation is a mathematical statement that shows that two expressions are equal.

It consists of variables, constants, and mathematical operations such as addition, subtraction, multiplication, division, exponents, and roots. Equations are used to solve problems and find unknown values.

We have,

We are given the equation 2.5(6x - 4) = 10 + 4(1.5 + 0.5x) and we need to find the value of x that satisfies this equation.

First, we can simplify both sides of the equation by using the distributive property of multiplication.

This gives us:

15x - 10 = 10 + 6 + 2x

Next, we can combine like terms on both sides of the equation. Specifically, we can combine the constants on the right-hand side:

15x - 10 = 16 + 2x

Now, we want to isolate the term with x on one side of the equation.

We can do this by subtracting 2x from both sides of the equation:

13x - 10 = 16

Finally, we can solve for x by adding 10 to both sides of the equation and then dividing both sides by 13:

13x = 26

x = 2

Therefore,

The value of x in the equation is 2.

La suma de las edades de los hermanos Carlos y Felipe es igual a la edad de su tía María; Si María tiene 29 años y Carlos tiene 13 años, ¿Cuántos años tiene Felipe?

Answers

Answer:

16 años

Step-by-step explanation:

Si la suma de la edad de Carlos y Felipe es igual a la de Maria, y en la pregunta nos dan la edad de Maria (M) y Carlos (C), entonces tenemos que encontrar la edad de Felipe. Para calcular esto necesitamos restar la edad de Carlos de la edad de Maria. Esto nos dara la edad exacta de Felipe (f).

M - C = f

29 - 13 = f

16 = f

Finalmente, vemos que la edad de Felipe es de 16 años

Please could I have the answers or step by step I don’t mind just PLEASEE help asap!!

Answers

Ok first you need to get a common denominator of 3 and 5 the smallest one would be 15 so then you rewrite both but remember if you do something to the bottom u have to do it to the top so you multiplied 3by 5 to get 15 to get your bottom then you have to times 5by 1 to get 5. So 5/15,same process for 3/5




5/15+ 9/15=9+5=14 so 14/15 (you keep the bottom the same) also it doesn’t need to be simplified because nothing can go into 14and 15 evenly





Same process for subtracting just subtract in the end so...

30/35-14/35= 16/35 also can’t be simplified evenly
In the end your answers are

1.14/15
2.16/35

A 64-ounce container of sports juice costs $6.50. A 48-ounce container of the same juice costs $4.25. Which juice container is the better buy.

Answers

Answer:

The juice container that is a better buy is the 48 ounce container because the price per ounce is lower.

Step-by-step explanation:

In order to determine the juice container that is the better buy, you have to find the one that has a lower cost per ounce by dividing the price of each juice container by the number of ounces it has:

64-ounce container: 6.50/64=0.10

48-ounce container: 4.25/48=0.08

According to this, the answer is that the juice container that is a better buy is the 48 ounce container because the price per ounce is lower.

In this extract, the narrator discusses what his life is like now, long after a traumatic ordeal with a ghostly woman who stole the life of his only son.CHRISTMAS EVEIt was nine-thirty on Christmas Eve. As I crossed the long entrance hall of Monks Piece on my way home from the dining room, where we had just enjoyed the first of the happy, festive meals, towards the drawing room and the fire around which my family were now assembled, I paused and then, as I often do in the course of an evening, went to the front door, opened it and stepped outside.I have always liked to take a breath of the evening, to smell the air, whether it is sweetly scented and balmy with the flowers of midsummer, pungent with the bonfires and leaf-mould of autumn, or crackling cold from frost and snow. I like to look about me at the sky above my head, whether there are moon or stars or utter blackness, and into the darkness ahead of me; I like to listen for the cries of nocturnal creatures and the moaning rise and fall of the wind, or the pattering of rain in the orchard trees, I enjoy the rush of air towards me up the hill from the flat pastures of the river valley.Tonight, I smelled at once, and with a lightning heart, that there had been a change in the weather. All the previous week, we had had rain, chilling rain and a mist that lay low about the house and over the countryside. From the windows, the view stretched not farther than a yard or two down the garden. It was wretched weather, never seeming to come fully light, and raw, too. There had been no pleasure in walking, the visibility was too poor for any shouting and the dogs were permanently morose and muddy. Inside the house, the lamps were lit throughout the day and the walls of larder outhouse and cellar oozed damp and smelled sour, the fires sputtered and smoked, burning dismally low.My spirits have for many years now been excessively affected by the ways of the weather, and I confess that, had it not been for the air of cheerfulness and bustle that prevailed in the rest of the house, I should have been quite cast down in gloom and lethargy, unable to enjoy the flavour of life as I should like and irritated by my own susceptibility. But Esme is merely stung by inclement weather into a spirited defiance, and so the preparations four our Christmas holiday had this year been more than usually extensive and vigorous.I took a step or two out from under the shadow of the house so that I could see around me in the moonlight. Monks piece stands at the summit of land that rises gently up for some four hundred feet from where the little River Nee traces its winding way in a north to south direction across this fertile, and sheltered, part of the century. Below us are pastures, interspersed with small clumps of mixed, broadleaf woodland. But at our backs for several square miles it is quite a different area of rough scrub and a heathland, a patch of wildness in the midst of a well-farmed country. We are but two miles from a good-sized village, seven from the principal market town, yet there is an air of remoteness and isolation which makes us feel ourselves to be much further from civilization.
