John borrowed $ from bank for 3 years at a rate of 10%

garik1379 [7]

<h3>Given:</h3>

P= $12500
R= 10%
T= 3 years

P= Principal amount
R= Rate of interest
T= Time period

The simple interest
The total amount paid

<h3>Solution:</h3>

$\large\boxed{Formula: I= \frac{PRT}{100}}$

First, we'll have to multiply, principal amount (12500), rate (10) and time period (3).

$12500×10×3$

$=375000$

Now, we'll have to divide the amount (375000) by 100.

$\frac{375000}{100}$

I=$3750

Now, we can find the total amount paid.

$\large\boxed{A=SI+P}$

Let's substitute according to the formula.

$A=3750+12500$

A=$16250

Therefore, simple interest is $3750 and $16250 was paid in total.

If angle KLJ~angle VWU. Find the x value

Alenkasestr [34]

Answer:

Step-by-step explanation:

Since angle KLJ~angle VWU are similar :

KL / WV = KJ/ UV

(25 / 20) = (4x - 23 / 2x + 2)

Cross multiply :

25(2x + 2) = 20(4x - 23)

50x + 50 = 80x - 460

50x - 80x = - 460 - 50

-30x = -510

x = 510 / 30

x = 17

Please hurry! If you don't know it, that's okay.

makvit [3.9K]

Answer:

The answer is (x,y)=(-10,-7)

Step-by-step explanation:

The solution comes from replace x= -10 into the equation of y=2/5 x -3.
Replacement of x= -10 into y = 2/5 x -3 results: $y=\frac{2}{5}\times{(-10)}-3=2\times{(-2)} -3=-4-3=-7$ .
