Answer:

Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.

Step-by-step explanation:

Let [tex]x[/tex] denote the number of rafts seating 3 people and [tex]y[/tex] the number of rafts seating 5 people. The total number of rafts is 13, so [tex]x+y=13[/tex]. We can also assume that every raft is filled to the brim (it isn't stated explicitly though, but it's probably the intention of the question maker), so [tex]3x+5y=53[/tex].

It's always a good idea to put these equations under each other:

[tex]\left \{ {{x+y = 13} \atop {3x+5y=53}} \right.[/tex]

We can subtract the first equation three times from the second one to obtain [tex](3x+5y)-3(x+y) = 53 - 3(13)\\3x-3x + 5y - 3y = 53 - 39\\2y = 14\\y=\frac{14}{2} = 7[/tex]

Now, substitute this found value for [tex]y[/tex] into [tex]x+y = 13[/tex] and we see that [tex]x=6[/tex]. We are now done: Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.

Answer: 5.2 units

Step-by-step explanation:

This is a right-angled triangle which means that the missing length can be solved using the Pythagorean theorem:

c² = a² + b²

Where c is the hypotenuse

a and b are the other sides.

c =  6

a = 3

b = ?

6² = 3² + b²

36 = 9 + b²

b² = 27

b = √27

b = 5.2 units

Answer:

[tex]y = \frac{4}{5} x -9.8[/tex]

Step-by-step explanation:

I hope this is what you were looking for.

Answer:

y=4/5x-9.8

Step-by-step explanation:

For this you would need to use point-slope form which is: y-y1=m(x-x1)

All you have to do is put in -5 for y1, 6 for x1, and 4/5 for m.

So, the equation should then be y+5=4/5(x-6)

Then, start by solving the right side of the equation by distributing 4/5 into (x-6)

This will then leave you with the equation, y+5=4/5x-24/5

Next, you have to subtract both sides by 5.

Once done, your final answer should be y=4/5x-9.8

Answer:

C=87

Step-by-step explanation:

To isolate the variable, you need to take away -57 by adding it to -144.

Then, you'd see:

-n=-87

Next, you divide both sides by -1 to get 87

A pergunta não está bem formatada. No entanto, pelo que parece óbvio

Responda:

3 horas

Explicação passo a passo:

Fração de hora gasta por sessão = 3/4 horas por sessão

Se o exercício for feito apenas aos domingos

Número de domingos por mês = 4

Portanto, número de sessões = 4

Fração de horas por sessão * Número de sessões

3/4 * 4 = 3 horas

Portanto, 3 horas são dedicadas ao exercício por mês

Answer:

B)

Step-by-step explanation:

1) the sum of angles of triangle is 180, then

180=25+33+E;

2) the measure of the angle E is:

E=180-25-33=122°

3) correct answer is B) 122°

Answer:

Step-by-step explanation:

r=d÷2

Multiply both sides by 2

d=2r

Please mark brainliest.

d = 2r

Simplification means to make any equation simple or any large equations to a simple form, simplification can be done with mathematical formula and done for all operators in mathematics.

Given r = d/2

when we transfer digits to other sides of equal they change their sign,

plus tends to minus or vice versa,

and multiply tends to divide or vice versa.

so d = 2r

Hence the solution for d is 2r
