5 0

I = p * r * t
p = 450
i = interest ??? That's what you are trying to find.
r = 12.1/100 = 0.121
t = 1 year

i = 450 * 0.121 * 1
i = 54.45 dollars.

A rectangle has a length of (x + 4) centimeters and a width of 12x centimeters. If the perimeter is 26 centimeters, what is the

mars1129 [50]

Width of rectangle is 8.4 cm

Step-by-step explanation:

Length of rectangle = x+4

Width of rectangle = 12x

Perimeter = 26 cm

We need to find width of rectangle.

The formula used is:

$Perimeter=2(length+width)$

Putting values and finding x first:

$Perimeter=2(length+width)$

$26=2(x+4+12x)$

$26=2(13x+4)$

$26=26x+8$

$26-8=26x$

$26x=18$

$x=\frac{18}{26}$

$x=0.7$

So, value of x is 0.7

Now width= 12x = 12(0.7)

=8.4 cm

So, width of rectangle is 8.4 cm.

What makes b in the equation true 3/8 X 8/b

Gala2k [10]

$\frac{3}{8} * \frac{8}{b} = \frac{3}{1} * \frac{1}{b}$ (I crossed simplify)

Next cross multiply;

3b = 1

b = 1/3

To check if the statement is true just substitute the value of b in the equation;

3b = 1

3(1/3) = 1

1 = 1
