Answer:

If x is 6, y is 9

Step-by-step explanation:

In your equation, substitute 6 in for each x. This would be (6) + 3y = 4(6) + y.

This ends up being 6 + 3y = 24 + y.

After that, you can subtract y from both sides to get 6 + 2y = 24.

Then you can subtract 6 from both sides to get 2y = 18.

Finally, divide both sides by 2 to get y = 9.

The ratio of dimes to quarters in a money bag is 12.2. If there are 8 quarters. How many dimes are there?

Answers

Answer:

98

Step-by-step explanation:

Given: The ratio of dimes to quarters in a money bag is 12.2

Also, there are 8 quarters.

To find: Number of dimes

Solution:

Number of dimes : Number of quarters = 12.2

Number of dimes : 8 = 12.2

Therefore,

Number of dimes = 12.2 × 8 = 97.6 ≈ 98

Jane works as a tutor for $14 an hour and as a waitress for $11 an hour. This month, she worked a combined total of 93 hours at her two jobs.

Answers

Answer:

3t + 1,023

Step-by-step explanation:

The computation is shown below:

As a tutor it is $14 per hour

As a waitress it is $11 per hour

Total number of hours worked is 93

Now let us assume the number of hours worked as a tutor is t

So as a waiter is 93 - t

Now the equation is

= $14(t) + $11(93 - t)

= 14t + 1,023 - 11t

= 3t + 1,023

From the set (76, 77, 78), use substitution to determine which value of x makes the equation true

Answers

Answer:

The answer is C.

Step-by-step explanation:

Multiply 4 by 76, 77, and 78.

4 * 76 = 304

4 * 77 = 308

4 * 78 = 312

304 = 304, so C is the correct answer.

What is 7.0483 rounded to the nearest hundredth?

Answer:

Step-by-step explanation:

The rounding off to the number nearest hundredth will be 7.048.

What is rounding off the numbers?

When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done.

A number can be rounded off to its lower value if the number after the decimal is between 0 and 4. The number will be rounded off to its higher value if the number after it is between 5 and 9.

The given number will be rounded off as below:-

7.0483 = 7.048

Therefore, the rounding off to the number nearest hundredth will be 7.048.

Dentro de cinco años mi abuelo tendrá el cuádruple de mi edad. Hace cinco años tenia siete veces mi edad¿que edad tenemos el y yo?

Answers

Answer:

La edad del abuelo es 75 años y la tuya es de 15 años.

 

Step-by-step explanation:

Si dentro de 5 años tu abuelo (A) tendrá el cuádruple de tu edad (E), tenemos:

[tex] A + 5 = 4(E + 5) [/tex]  (1)

Ahora, si hace cinco años tenia siete veces tu edad:

[tex] A - 5 = 7(E - 5) [/tex]    (2)

Multiplicando la ecuacion (1) por -1, tenemos:

[tex] -A - 5 = -4(E + 5) [/tex]   (3)

Ahora sumando la ecuación (3) con (2):

[tex] -10 = 3E - 55 [/tex]

[tex] E = 15 [/tex]

Entonces, reemplazando el valor de E en la ecuación (1):

[tex] A + 5 = 4(15 + 5) [/tex]

[tex] A = 75 [/tex]

Por lo tanto, la edad del abuelo es 75 años y la tuya es de 15 años.

Help me solve thank you will give 20 points

Answers

Answer:

Natalie bought 500 apples at $0.40 each, then she pays $0.40 500 times, this means that the total cost of the 500 apples is:

Cost = 500*$0.40 = $200

Now she threw away n apples from the 500 apples, then the number of apples that she has now is:

apples = 500 - n

And she sells the remaining apples for $0.70 each.

a) The amount that she gets by selling the apples is:

Revenue = (500 - n)*$0.70

b) We know that she did not make a loss, then the revenue must be larger than the cost, this means that:

cost ≤ revenue

$200 ≤ (500 - n)*$0.70

c) We need to solve the inequality for n.

$200 ≤ (500 - n)*$0.70

$200/$0.70 ≤ (500 - n)

285.7  ≤ 500 - n

n + 285.7 ≤ 500

n ≤ 500 - 285.7

n ≤ 214.3

Then the maximum value of n must be equal or smaller than 214.3

And n is a whole number, then we can conclude that the maximum number of rotten apples can be 214.

Algebra I

Standard Form: ax² + bx + c = 0

Discriminant: b² - 4ac

Positive - 2 solutions Equal to 0 - 1 solution Negative - No solutions/Imaginary

Step-by-step explanation:

Step 1: Define

x² - 6x - 10 = 0

Step 2: Identify Variables

Compare quadratic.

x² - 6x - 10 = 0 ↔ ax² + bx + c = 0

a = 1, b = -6, c = -10

Step 3: Find Discriminant

Substitute in variables [Discriminant]:                                                            (-6)² - 4(1)(-10)[Discriminant] Evaluate exponents:                                                                36 - 4(1)(-10)[Discriminant] Multiply:                                                                                    36 + 40[Discriminant] Add:                                                                                          76

This tells us that our quadratic has 2 real solutions.

The Strange Case of Dr. Jekyll and Mr. Hydeby Robert Louis StevensonPart 11. Mr. Utterson the lawyer was a man of a rugged countenance, that was never lighted by a smile; cold, scanty and embarrassed in discourse; backward in sentiment; lean, long, dusty, dreary, and yet somehow lovable. At friendly meetings, and when the wine was to his taste, something eminently human beaconed from his eye; something indeed which never found its way into his talk, but which spoke not only in these silent symbols of the after-dinner face, but more often and loudly in the acts of his life. He was austere with himself; drank gin when he was alone, to mortify a taste for vintages; and though he enjoyed the theatre, had not crossed the doors of one for twenty years. But he had an approved tolerance for others; sometimes wondering, almost with envy, at the high pressure of spirits involved in their misdeeds; and in any extremity inclined to help rather than to reprove.2. "I incline to, Cain's heresy*," he used to say. "I let my brother go to the devil in his quaintly 'own way.'" In this character, it was frequently his fortune to be the last reputable acquaintance and the last good influence in the lives of down-going men. And to such as these, so long as they came about his chambers, he never marked a shade of change in his demeanour.3. No doubt the feat was easy to Mr. Utterson; for he was undemonstrative at the best, and even his friendship seemed to be founded in a similar catholicity of good-nature. It is the mark of a modest man to accept his friendly circle ready-made from the hands of opportunity; and that was the lawyer's way. His friends were those of his own blood or those whom he had known the longest; his affections, like ivy, were the growth of time, they implied no aptness in the object. Hence, no doubt, the bond that united him to Mr. Richard Enfield, his distant kinsman, the well-known man about town. It was a nut to crack for many, what these two could see in each other, or what subject they could find in common. It was reported by those who encountered them in their Sunday walks, that they said nothing, looked singularly dull, and would hail with obvious relief the appearance of a friend. For all that, the two men put the greatest store by these excursions, counted them the chief jewel of each week, and not only set aside occasions of pleasure, but even resisted the calls of business, that they might enjoy them uninterrupted.*The biblical story of Cain and Abel is a story about two brothers who gave offerings to God. Abel's offering was accepted by God, but Cain's was not. Jealous, Cain killed his brother. When God asked Cain where Abel was, Cain said, Am I my brother's keeper? By saying this, Cain implied that what his brother did was his own business.
