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.

Factors of 84 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42 and 84

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

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:

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

Answer: 2

Step-by-step explanation: That expression is a binomial in any case the terms in a polynomial are separated by a plus or minus sign (+,-) so you can determine the number of terms by counting how many number or variable are being separated (ex: 3a+a-1 would have 3 terms and be a trinomial)

Answer:

x = 57

Step-by-step explanation:

42 + 15 = 57

Answer:

a = -bc

Step-by-step explanation:

We are given the equation:

c = -a/b

Because multiplication and division are inverse operations, if we move b over to the other side, since it was dividing on the right side, it would be multiplied on the other side (I don't know how to explain that well)

so you can make it look like this:

b*c = -a

Or:

-a = b*c

Then, do isolate a, we will have to divide by -1 on both sides

a = -b*c

To check this, we can plug in numbers

-8 = -16/2

-16 = -8*2

16 = 8 * 2

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

Step-by-step explanation:

Answer:

`1. You deposit $950 in an account that earns 9% annual interest compounded daily.

2.You deposit $1000 in an account that earns 8% annual interest compounded daily.

3. You deposit $1000 in an account that earns 9% annual interest compounded semiannually.

Step-by-step explanation:

Trick question, number 3 says semiannually so it is only twice a year, so it is the least. In math papa or any algebra calculator, put in the two equations and compare which is greater, in this case, y = 950(1.09)^10 is greater than y=1000(1.08)^10

Accounts according to their values after 10 years, from greatest to least. are Account 3, Account 1, Account 2 and Account 4.

percentage, a relative value indicating hundredth parts of any quantity.

The formula for daily compounding is:

[tex]A = P(1 + r/n)^{nt}[/tex]

where A is the future value,

P is the principal amount,

r is the annual interest rate,

n is the number of times the interest is compounded per year, and t is the time in years.

When we deposit $950 in an account that earns 9% annual interest compounded daily.

A = 950(1 + 0.09/365)³⁶⁵⁰

= $2,436.24

Deposit $1000 in an account that earns 8% annual interest compounded daily.

A = 1000(1 + 0.08/365)³⁶⁵⁰

= $2,223.97

Deposit $1000 in an account that earns 9% annual interest compounded semiannually.

A = 1000(1 + 0.09/2)²⁰

= $2,471.52

Deposit $1000 in an account that earns 10% simple interest.

The formula for simple interest is:

A = P(1 + rt)

where A is the future value, P is the principal amount, r is the annual interest rate, and t is the time in years.

Using this formula, we get:

A = 1000(1 + 0.10(10))

= $2,000

Now we can order the accounts from greatest to least based on their future values after 10 years:

Account 3: $2,471.52

Account 1: $2,436.24

Account 2: $2,223.97

Account 4: $2,000

Hence, accounts according to their values after 10 years, from greatest to least. are Account 3, Account 1, Account 2 and Account 4.
