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.

Please help me please guys please guy
Answer:
[tex]y = 2 {(x - 3)}^{2} + 1[/tex]
Answer:
D) 2(x - 3)² + 1
Step-by-step explanation:
First off:
the equations are in y = a(x-h)²+k format.
So, that means that since the vtx is (3, 1), the answers could only be c or d
The difference between the two is one parabola is reflected (negative) and the other is facing up. Since (1, 9) is above the vtx, only D is the one that passes through (1, 9) because it is the only one facing upward to touch that point.
sin( x+ π/4) + sin( x− π/4 ) = 1

1. What is the value of n in -57 - n = -144?
A-201
B-87
C 87
D 201
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

de hora de aeróbicos y
hora de máquinas en el gimnasio; si ella va a
gimnasio solamente los domingos durante un mes, ¿cuántas horas dedica a ejercitarse?
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

Solve for d in terms of r.
r=d/2
d=
Answer:
Step-by-step explanation:
r=d÷2
Multiply both sides by 2
d=2r
Please mark brainliest.
d = 2r
What is simplification?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
