Consider the system of equations.
jok3333 [9.3K]

Given:

The system of equations:

x-3y=9

\dfrac{1}{5}x-2y=-1

To find:

The number that can be multiplied by the second equation to eliminate the x-variable when the equations are added together.

Solution:

We have,

x-3y=9                        ...(i)

\dfrac{1}{5}x-2y=-1       ...(ii)

The coefficient of x in (i) and (ii) are 1 and \dfrac{1}{5} respectively.

To eliminate the variable x by adding the equations, we need the coefficients of x as the additive inverse of each other, i.e, a and -a So, a+(-a)=0.

It means, we have to convert \dfrac{1}{5} into -1. It is possible if we multiply the equation (ii) by -5.

On multiplying equation (ii) by -5, we get

-x+10y=5       ...(iii)

On adding (i) and (iii), we get

7y=14

Here, x is eliminated.

Therefore, the number -5 can be multiplied by the second equation to eliminate the x-variable.

Answer: 3 1/3

Step-by-step explanation:

Turned into mixed numbers: -7/3 + 17/3

Multiply all the numbers by 3: -7 * 3 = -21

17 * 3 = 51

3 * 3 = 9

-21 + 51 = 30

30/9

30/9 = 3 1/3

At what rate per annum does the compound interest of Rs 576 becomes to Rs 153 in 2 years
ArbitrLikvidat [17]

Answer:

The value of rate per annum is R = 12.5 %

Step-by-step explanation:

Principal amount = 576

Interest = 153

Amount after 2 years = 576 + 153 = 729

We know that

A = P [1 + \frac{R}{100} ] ^{T}

Put all the values in above equation

729 = 576 [1 + \frac{R}{100} ]^{2}

\frac{27}{24} = 1 + \frac{R}{100}

R = 12.5 %

This is the value of rate per annum.
