Given is 9(2y + 1) = -6(2 - 3y)

9(2y + 1) = -6(2 - 3y)\\\\18y + 9 = -12 + 18y\\\\18y - 18y = 9 + 12 = 21\\\\inconsistent\;\;system

It means there is no solution for this system of equations.

SVETLANKA909090 [29]
Starting January 1, 2015, there are 364 remaining nights.
From 1,001 nights, it will be 637 nights left.

In 2016, there are 366 nights. Subtract it to 637 nights left, you will get 271 nights left.
In 2017, 271 is lesser than 365.
From January to August, the nights left is 28.

Answer:

The density of cube is 6.17959 \frac{g}{cm^{3} }

Step-by-step explanation:

The density is given by ration of a mass of body and volume occupied by a body.

\rho = \frac{m}{V}

Where,

\rho is density.

m is mass of a body

V is the volume of a body

Given that one side of the cube is 0.53cm

Hence, the volume of a body is V=0.53^{3}=0.148877cm^{3}

Now, the Density of the cube will be

\rho = \frac{m}{V}

\rho = \frac{0.92}{0.148877}

\rho =6.17959

Thus, The density of cube is 6.17959 \frac{g}{cm^{3} }

From the explicit formula:
an=3+(n-1)8
simplifying this we get:
an=3+8n-8
an=8n-5
thus 
the recursive formula is:
an=an-1+

Sindi borrowed an amount of money from his
PolarNik [594]

The present value of the loan is R576923.

<h3>What is compound interest ?</h3>

Compound interest is giving the current instalment in terms of the total previous amount.

The formula is given by

A = P(1 + r/100)ⁿ.

Where,

A = Amount, P = Principle, r = rate of interest, n = Time in years.

In case the compound if interest is given every two months that is 6 instalments each year the above given formula will be

A = P{ 1 + (r/6)/100 }⁶ⁿ.

According to the given question

Rate(r) = 7.5%

Time(n) = 6 years

The loan will be paid back in 6 years every second month and it is compounded.

∴ No. of instalments = (12 × 6)/2

= 36.

Now each instalments is of R25000

So, The total amount she has to pay back to his father is

= (25000 × 36)

= R900000.

We know compounding every two months is

A = P(1 + r/100)ⁿ

900000 = P{ 1 + (7.6/6)/100 }³⁶

900000 = P{ 1 + 1.25/100 } ³⁶

900000 = P(1.0125)³⁶

900000 = 1.56P

∴ P = 576923.
