Jan uses 22.5 gallons of water in the shower. This amount is 7.5 gallons less than what she uses when washing her clothes. Write

arsen [322]

22.5 (shower) = X (variable used in place of the amount of water she uses to wash clothes) - 7.5 (the amount she used in the shower is 7.5 gallons less than she uses for washing clothes)

22.5 = X - 7.5 《 This is the equation.

Solve is by adding 7.5 to both sides to cancel out the negative 7.5 and you get (X = 30).

If you divide 6 by 8= 0.75, which is equivalent to 75%. So Amber made 75% of her free throws.

Mean is the "meanest" because it requires the most work. Add up the values in your data set and divide by the number of terms in the data.

Let x represent attendees at Harry's Hoedown, then

Mean = $\frac{Martha's (M) + Shirly's (S) + Harry's (x) }{3}$

41 = $\frac{48 + 33 + x}{3}$

123 = 48 + 33 + x

123 = 81 + x

42 = x
