Answer:
1= 0.109
2= 3.46
3 = -(minus)1.24
Step-by-step explanation:
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).
A. 0.25
B. 0.6
C. 0.721
D. 0.07
E. 0.095
F. .0066
When you convert percentages into decimals always move the . two spaces to the left.
Set the angles equal to 180
x + 2x + 3x = 180
6x = 180
Solve for x
6x = 180
x = 30
Plug that into angle C
2(30) = 60
Angle C is 60 degrees
