So you set up your equation, $\frac{x}{100}$ · $\frac{13}{65}$
Cross multiply and get 1300=65x.
Divde both sides by 65, get x= 20
So, 13 is 20% of 65.
Hope this helps

6(x-5) = 5(x+5)

Mariana [72]

Part 1:

6(x-5) = 5(x+5) (x = 55)

4y + 2 (-3 + 2y) = 1-y (x = 7/9)

Part 2:

4(a-6) = 8a - (4a-24) (No Solution)

4(2x-8) = 8(x-8) (No Solution)

2(3x-3) = -6x-6 (Identity (x = 0))

Helpppppppppp please

eduard

You know b=-6 and since you know this, you can plug -6 in for b.

This would become 4(-6) + 6 divided by 6.

You can then multiply 4 and -6 together,

-24 + 6 / 6

You can then add -24 and 6 together,

-18/6

You can then divide -18 by 6,

-18/6=-3

-3 is your final answer

The area of a rectangle is 30 square root 3750 square inches, and the length is 3 square root 250 inches what is the width of th

Ann [662]

Answer:

$width=10\sqrt{15}\ in$

Step-by-step explanation:

-A rectangle's area is given by:

$A=lw\\\\l=length\\w=width$

Given A= $30\sqrt{3750}$ and $l=3\sqrt{250}$ , we substitute in the formula to solve for the width as follows:

$A=lw\\\\30\sqrt{3750}=3\sqrt{250}\times w\\\\w=\frac{30\sqrt{3750}}{3\sqrt{250}}\\\\w=10\frac{\sqrt{3750}}{\sqrt{250}}\\\\=10\times \sqrt{\frac{3750}{250}}\\\\=10\sqrt{15}\ in$

Hence , the rectangle's width is $10\sqrt{15}\ in$
