Length: 2x-1, width: x

A=LW

120=x(2x-1) 120=2x^2-x 0=2x^2-x-120, Factor (x-8)(2x+15)=0

x=8 is the width and 15 is the length

What is 5/16 written as a percent?

Rom4ik [11]

First, you divide the fraction, and then you multiply it by 100.
So you get:
$\frac{5}{16} * 100$
$0.3125 * 100$
$31.25$

So, 5/16 is 31.25%

Hope this Helps! :)

I need help pls and thank you...

Answer:

AB = 32

Step-by-step explanation:

Since line l bisects AB at point M, we have AM = MB.

$4x = 5x - 4$

$4x + 4 = 5x$

$x = 4$

AM = 4(4) = 16, MB = 5(4) - 4 = 16.

So AB = AM + MB = 16 + 16 = 32.

Kareem and Marco went to the mall. Kareem spent $8 less than Marco spent at the mall. Kareem spent more than $15. Write an inequ

mestny [16]

Marco spent more than $23. M > 23

We know the Kareem spent 8 less than Marco and that Kareem spent more than 15. If we add 8 onto the 15, we know that Marco has to be more than 23.

To graph this, draw an open circle at 23 and have an arrow going to the right.
