Answer:
50+ 20x= y
25+ 40x= y
Explanation:
For Billy and Susie, the starting values are $50 and $25. You simply add that to the money saved per week ($20 and $40).
x= number of weeks
Water in the swimming pool initially = 2.5 million liters
Water in the swimming pool after evaporation = 2 million liters
Therefore, volume of water evaporated = 2.5 million liters - 2 million liters
=0.5 million liters
To find the percent of water evaporated, divide the volume of water evaporated by the volume of water in the swimming pool initially and then multiply it by 100.
Percent of water evaporated =( 0.5 / 2.5) x 100 =20%
Answer:
1. w = 3l
2. k = 1/2 * b
Step-by-step explanation:
1. w = 3l
w = width l = length
Since we are solving the equation for the width, we can make the equation w = ? for now. since the width is equal to three times the length, we can make the equation w = 3l.
2. k = 1/2 * b
k = kool-aid b = beef
Since we are solving the equation for the kool-aid, we can make the equation k = ? for now. since the kool-aid is equal to half the beef sold, we can make the equation k = 1/2 * b
