Step by step equation
Square root
2x - 30 = -2(x + 3) =
2x - 30 = -2x - 6
2x + 2x = -6 + 30
4x = 24
x = 24/4
x = 6
Total no. of teas served: 20
Therefore, we can write the two quantities as fractions of twenty:
14/20 and 6/20
A percentage is "per-cent", i.e. per 100, therefore a fraction of 100. To make this denominator a fraction of 100 we multiply it by 5 (20 x 5 = 100), and because what we do to the bottom of the fraction we must do to the top, we multiply each numerator by 5:
14/20; 14 x 5 = 70
6/20; 6 x 5 = 30
So,
70/100 , 30/100
Answer: 70% of the teas sold were caffeinated.
Given that the tent is in a shape of rectangular prism the volume of the prism will be given by:
volume=[base area]*[height]
since the base area is a triangle, the volume will be:
Volume=[1/2*a*b]*height
The answer is 540.
34 tens is 340, and 20 tens is 200. Together the sum is 540.
