You're solving an equation approximating the number of farm.incidents in Wales and England between 1980-88.

F = 3500
3500 = 250x - 493000
3500 + 493000 = 250x
496500 = 250x
496500/250 = x
1986 = x

Twice as many men as women attended the concert. If the total attendance was 714, how many women
mixas84 [53]

Answer:

Step-by-step explanation:

This is actually pretty simple. If x= a person, then 2x is men, and x is women.

You just have to solve for x.

714=2x+x

714=3x

x=238

Then you have to multiply it back out.

Men: 476

Women: 238

I hope this helps!

A right rectangular prism has a volume of 470.40 cm³. The length of the solid is 6.4 cm and the width is 9.8 cm.
Bogdan [553]
V = l * w * h
470.40 = 6.4 * 9.8 * h
Multiply the length and width on the right side of the equation.

470.40 = 62.72 * h
Divide both sides by 62.72
7.5 cm = h

CHECK
V = l * w * h
V = 6.4 * 9.8 * 7.5
V = 470.4 cm^3
