3. A study team is discussing multiplying integers.

Scott says, "Two negatives multiply to make a negative and two positives multiply to make a positive."

Aaron says, "No, it depends on what there are more of', like -10(3) is negative, but 5(-2) is positive."

Zachary says, "If the signs are the same it is positive, but if they signs are different, the product is

negative."

Tina disagrees. "The sign of the product is the sign of the first number being multiplied."

Who, if anyone, is correct? Give at least three examples to illustrate the concept these students are

debating.

The monthly interest is $1.15.

Answer:

$255.20

Step-by-step explanation:

Answer:

$7,300 was invested in the 14% account while $2,700 was invested in the 8% interest account

Step-by-step explanation:

Let the amount invested in first account be $x while the amount for second account is $y

Mathematically;

x + y = 10,000 •••••••••(i)

Interest on first account

= 14% of x = 14/100 * x

Interest on second account

= 8% of y= 8/100 * y

Adding all together will give total

14/100 * x + 8/100 * y = 1238

Multiply through by 100

14x + 8y = 123800 •••••••(ii)

From equation 1, x = 10,000 - y

Insert this into second equation

14(10,000-y) + 8y = 123,800

140,000 - 14y + 8y = 123,800

140,000 - 6y = 123,800

6y = 140,000 - 123,800

6y = 16,200

y = 16,200/6

y = $2,700

Recall

x + y = 10,000

x = 10000 - y

x = 10,000 - 2,700

x = $7,300

Answer:

Step-by-step explanation:

C. Cost = $19 x u + $9shipping fee

So k = 19u + 9

The function that represent the information is k = 19u + 9

The shipping fee = $9

The company charges $19 per costume.

The shipping fee is acting like a constant in the linear equation while the amount charged for the costumes is dependent on the value u, which is the number of costumes purchased.

k = total cost

number of costumes she orders = u

Therefore, the equation can be represented as follows

k = 19u + 9

Answer:

$10

Step-by-step explanation:

Total amount earned = $2400

Less: federal and state taxes, social security, and health insurance = $550

Balance = $2400 - $550

=$1,850

Less : Rent = $1,000

Balance = $1,850 - $1,000

= $850

Less: insurance = $700

Balance = $850 - $700

= $150

He has to divide the remaining total up equally and make it last for 15 days

Amount to spend per day = $150 / 15 days

= $10 per day

Answer:

7. Perimeter = x+12

8.  Area = 3x² +19x-8

Step-by-step explanation:

Perimeter -To calculate the perimeter of a triangle, add the length of its sides. For example, if a triangle has sides a, b, and c, then the perimeter of that triangle will be P = a + b + c.

Area -The area A of a rectangle is given by the formula, A=lw, where l is the length and w is the width.

Complete question is;

Summer and Autumn are friends who live 25 miles apart and they are training for a long race. On wednesday after school, they ran toward each other’s houses to meet up. They left their houses at 4pm and met at 6 pm. Summer ran an average rate of 8 ½ miles per hour faster than autumn. What is the average speed of each?

Answer:

Autumn's average speed is 1.3158 mph

Summer's average speed is 11.1843 mph

Step-by-step explanation:

We are told that they live 25 miles from each other.

They left their houses at 4pm and met at 6 pm. This means they met 2 hours later.

Now, summer ran 8.5 mph faster than autumn.

This means if autumn's speed is "x", then summer ran 8.5x mph

Thus, total distance covered by summer is; d_summer = 8.5x * 2 = 17x

Total distance by autumn is; x * 2 = 2x

Since their houses are 25 miles apart.

Thus;

17x + 2x = 25

19x = 25

x = 25/19

x = 1.3158 mph

Thus, autumn's speed is 1.3158 mph

Summer's speed is 1.3158 × 8.5 = 11.1843 mph

Answer:

making it very simple it is D Edge 2021

Step-by-step explanation:

The correct option is △ TUX ≅ △ TSV

CPCTC stands for "corresponding parts of congruent triangles are congruent" and tells us if two or more triangles are congruent, then their corresponding angles and sides are congruent as well.

Given that, △STU an equilateral triangle and ∠TXU ≅ ∠ TVS, and UX ≅ SV by CPCTC so,

∠TXU ≅ ∠TVS →  given

∠STV ≅ ∠UTX → reflex. prop.

△STU is an equilateral triangle →  given

ST ≅ UT  → sides of an equilat. △ are ≅

△ TUX ≅ △ TSV by AAS rule

UX ≅ SV by CPCTC

According to the given proof, the only option fitting is option D.

Hence, The correct option is △ TUX ≅ △ TSV

Answer:

Ana tiene 166,67 dólares, mientras que Sergio tiene 333,33 dólares.

Step-by-step explanation:

Consideramos que la mejor estrategia para resolver este problema consiste en leer cuidadosamente cada frase del enunciado, traducirlo matemáticamente y utilizar software gráfico para determinar la solución de las ecuaciones resultantes:

1) Entre Ana y Sergio tienen $ 500

[tex]x + y = 500[/tex] (Eq. 1)

Donde:

[tex]x[/tex] - Cantidad de dinero de Ana, medida en dólares.

[tex]y[/tex] - Cantidad de dinero de Sergio, medida en dólares.

2) Sergio tiene el doble de dólares que Ana

[tex]2\cdot x - y = 0[/tex] (Eq. 2)

En consencuencia, tenemos un sistema de dos ecuaciones lineales con dos incógnitas, lo que nos permite la posibilidad de encontrar una solución única y utilizar un plano cartesiano para su resolución. Mediante software gráfico (véase imagen adjunta) encontramos que la solución del sistema es:

[tex](x,y) = (166,67, 333,33)[/tex]

Ana tiene 166,67 dólares, mientras que Sergio tiene 333,33 dólares.
