Answer:

Step-by-step explanation:

Simplifying

2.1x + -5.7 = 3.9(4.3 + -1.8x)

Reorder the terms:

-5.7 + 2.1x = 3.9(4.3 + -1.8x)

-5.7 + 2.1x = (4.3 * 3.9 + -1.8x * 3.9)

-5.7 + 2.1x = (16.77 + -7.02x)

Solving

-5.7 + 2.1x = 16.77 + -7.02x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '7.02x' to each side of the equation.

-5.7 + 2.1x + 7.02x = 16.77 + -7.02x + 7.02x

Combine like terms: 2.1x + 7.02x = 9.12x

-5.7 + 9.12x = 16.77 + -7.02x + 7.02x

Combine like terms: -7.02x + 7.02x = 0.00

-5.7 + 9.12x = 16.77 + 0.00

-5.7 + 9.12x = 16.77

Add '5.7' to each side of the equation.

-5.7 + 5.7 + 9.12x = 16.77 + 5.7

Combine like terms: -5.7 + 5.7 = 0.0

0.0 + 9.12x = 16.77 + 5.7

9.12x = 16.77 + 5.7

Combine like terms: 16.77 + 5.7 = 22.47

9.12x = 22.47

Divide each side by '9.12'.

x = 2.463815789

Simplifying

x = 2.463815789

What is the future value of a R 75 000 deposit made every 6 months for 3 years using an annual rate of 10% compounded semi-annua

dolphi86 [110]

Answer:

The future value is: RS 132867.075

Step-by-step explanation:

Given

$PV = 75000$ --- present value

$r = 10\%$ --- annual rate

$n = 6$ --- number of times compounded (3 years/ 6 months)

Required

The future value

This is calculated as:

$FV =PV * (1 + r)^n$

$FV = 75000 * (1 + 10\%)^6$

$FV = 75000 * (1 + 0.10)^6$

$FV = 75000 * (1.10)^6$

$FV = 132867.075$

<em>Hence, the future value is: RS 132867.075</em>

Lucia flips a coin three times. What is the probability she gets (Head, tail, Head) in that order?

Svetach [21]

Answer: $\dfrac{1}{8}$

Step-by-step explanation:

The total outcomes of tossing a coin = 2

The total number of possible outcomes of flipping coin three times =2 x 2 x 2 = 8

Favorable outcome= (Head, tail, Head) in order

i.e. Number of Favorable outcomes = 1

We know that , Probability = $\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}$

Therefore , The required probability $=\dfrac{1}{8}$

Hence , the probability she gets (Head, tail, Head) in that order $=\dfrac{1}{8}$
