Answer:

x = -13

Step-by-step explanation:

Distribute:

8 - 6x + 10x - 15 = 20 - 5x

Combine like terms:

4x - 7 = 20 - 5x

Isolate Variable

-x = 13

-1(-x) = -1(13)

x = -13

Answer: x=3

Step-by-step explanation:

You need to apply Distributive property on the left side of the equation:

2(4-3x)+5(2x-3)=20-5x\\\\8-6x+10x-15=20-5x

Now you must add the like terms on the left side of the equation:

-7+4x=20-5x

Add 5x to both sides:

-7+4x+5x=20-5x+5x\\\\-7+9x=20

Add 7 to boht sides of the equation:

-7+9x+7=20+7\\\\9x=27

And finally, divide both sides by 9:

\frac{9x}{9}=\frac{27}{9}\\\\x=3

What is the present value of 6000 received 14 years from today when the interest rate is 10%
likoan [24]

Answer:

$14400

Step-by-step explanation:

Given data

Principal= 6000

Time= 14 years

Rate= 10%

Let us use the simple interest expression to find the final amount

A=P(1+rt)

substitute

A=6000(1+0.1*14)

A=6000(1+1.4)

A=6000*2.4

A=$14400

Hence based on a simple interest model the final amount is $14400

Sam invests $6000 in two different accounts. The first account paid 12 %, the second account paid 7 % in interest. At the end of
Lunna [17]

Answer:

The amount in the account at 12% interest is $3400 and the amount in the second account at 7% interest is $2600

Step-by-step explanation:

Let x be the amount in the account at 12% interest

So, 6000-x is the amount in the second account at 7% interest

SI = \frac{P \times T \times R}{100}

First account:SI=\frac{x \times 1 \times 12}{100}

Second account : SI =\frac{(6000-x) \times 1 \times 7}{100}

We are given that At the end of the first year he had earned $590 in interest.

So, \frac{x \times 1 \times 12}{100}+\frac{(6000-x) \times 1 \times 7}{100}=590\\x=3400

So,the amount in the account at 12% interest is $3400

The amount in the second account at 7% interest =6000-x=6000-3400=2600

Hence the amount in the account at 12% interest is $3400 and the amount in the second account at 7% interest is $2600
