Please help me add 5 3/4 + (-1/4), - 2/3 + 1/6, 8/5 + (- 3/4).

Answer:

the fist one = 160 - 24

the second one = 12.50 / 5

Step-by-step explanation:

Answer:

15. equation: g+24=160, and the answer is g=136

16. equation: 5d=12.50, answer is d=3.5 hours

17. 15 cakes are made when the cost is $395

Step-by-step explanation:

15: You know that there are 160 students in 7th grade. This would be on one side of the equal sign. You know that there are 24 more students in the 7th grade class than the 8th grade class. And we know that g represents the number of students in the 8th grade class. So you set up your equation as g+24=160. You would subtract 24 from both sides: g+24-24=160-24, which gives you g=136.

16: You spend $5 an hour, so, on one side, you will have 5. On the other you will have $12.50. We will let d represent dollars, and it will go with the 5 to give us 5d. The equation is 5d=12.50. From there, you will divide 5 from both sides: 5d/5=12.50/5, which gives you d=3.5.

17:  So, we have the equation, and we just plug in what we know. So, $395=24n+35. From there, we will subtract 35 from both sides. That would give us $395=24n and we will divide 24 from both sides to give us n=15 cakes.

Answer:

PN= $17,800

Step-by-step explanation:

La formula general para calcular el activo de una empresa es la siguiente:

A= PN + P

El activo es igual al patrimonio neto y el pasivo.

Debemos intercambiar los términos:

PN= A - P

Activo:

Caja= 10,000

Bancos= 13,500

Equipos de computación= 2,400

Documentos por cobrar= 5,100

Pasivo:

Cuentas por pagar= 8,000

Documentos por pagar= 4,000

Intereses por pagar= 1,200

PN= 31,000 - 13,200

PN= $17,800

Answer:

d. 242..................

Answer:

d

Step-by-step explanation:

The sum to n terms of an arithmetic sequence is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 3 and d = 5, thus

[tex]S_{11}[/tex] = [tex]\frac{11}{2}[/tex] [ (2 × - 3) + (10 × 5) ]

      = 5.5(- 6 + 50)

       = 5.5 × 44

       = 242 → d

The two parallel lines will be b and d in the given question

From the figure, we can see that

Angles formed by lines b and a are 89. 5 degrees

Angles formed by lines c and a are 91.5 degrees

Angles formed by lines d and a are 89.5 degrees

Angles formed by lines e and a are  88.5 degrees

Angles formed by lines f and a are   90.5 degrees

Since the angle formed by line b with a and d with a are equal that is 89.5

so these two lines will never intersect each other

But other lines have varied angles then they can intersect at one point

Thus the two parallel lines will be b and d in the given question

Daniel is...remember "is" in a word problem means "equal"

So Daniel=x+26. x representing Daniel's son's age which we do not know.

In six years he will be three times his son's age, "times" meaning multiplication.

Daniel+6=3x, so just equate the two equations. So you must solve;

Step-by-step explanation:

If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence. The constant difference in all pairs of consecutive or successive numbers in a sequence is called the common difference, denoted by the letter d.

It is given that the expression  [tex]\rm \frac{sin\theta sec\theta}{cos\theta tan\theta}[/tex]

It is required to find the simpler form from the given options.

The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

The series: 2 + 4 + 6 +.... is an arithmetic series

The sum of T41 to T47 is 616

The series is given as:

2 + 4 + 6 +....

The above series is an arithmetic series with the following parameters:

Initial value, a = 2

Common difference, d = 2

Start by calculating S40 using the sum of n terms formula

[tex]S_n = \frac n2 * [2a + (n - 1)d][/tex]

So, we have:

[tex]S_{40} = \frac {40}2 * [2*2 + (40 - 1)*2][/tex]

[tex]S_{40} = 1640[/tex]

Calculate S47 using the same formula

[tex]S_{47} = \frac {47}2 * [2*2 + (47 - 1)*2][/tex]

[tex]S_{47} = 2256[/tex]

Subtract S40 from S47

[tex]S_{47} - S_{40} = 2256 - 1640[/tex]

[tex]S_{47} - S_{40} = 616[/tex]

Hence, the sum of T41 to T47 is 616
