To answer this problem, we let x be the number of hours working on weekdays and y be the number of hours working on nights and weekends. The sum of these two variables should be equal to 50. The system of linear equation that would best represent this problem is,
x + y = 50
80x + 120y = 4800
Answer:
p=75(alternative) , t=105(sum of all sides) ,
q=105(sum of all sides) , s=105(straight angle)
r=75(sum of all sides)
First you need to find out how many cm of water that will be saved after brushing your teeth 3 times.
379 x 3 = 1137
Next you need the convert the cm to liters. You do this by dividing the cm total by 1000.
1137 / 1000 = 1.137
So you would save 1.137 liters of water while brushing your teeth 3 times.
Hope this helps!!
Answer:8.9
Step-by-step explanation:
192/43 is about 4.46
4.46*2 is about 8.9
Answer:
If only Jim purchased a cup of coffee, we will subtract its cost from the total;
9.50 - 1.00 = 8.50
Assuming that the two purchased nothing else for breakfast, and that the cost of an egg scramble was the same for both, let's call the price of the egg scramble x.
Since they both bought eggs, then 2x = 8.50
x = $4.25, the price for each egg scramble
