The talent show consists of introduction and talent performance. It could be written into this equation
Talent show duration= introduction + talent performance
Each performer for the talent show has 6 minutes for their show, the <span>introduction of the talent show is 24 minutes, and the total duration should be 150 minutes. Then, maximum performance count of the show would be:
</span>
Talent show duration= introduction + talent performance
<span>150 min = 24 min + (performance count * 6min)
</span>performance count = (150min - 24min) / 6 min
performance count=21
Answer:
Solution is invalid
Step-by-step explanation:
Let the time when they will have the same water content be x hours
At x hours;
For the first tank, the content will be;
50 + 10x
For the second;
29 + 3x
Equating both, will give us x
29 + 3x = 50 + 10x
We will get x as a negative number here
Since number of hours can not be negative, the solution is invalid
Answer:
9 bottles of soda and 7 bottles of juice
Step-by-step explanation:
Let x be the number of bottles of soda purchased and y be the number of bottles of juice purchased.
1. Gabriel purchased 2 more bottles of soda than bottles of juice, then

2. Each bottle of soda has 35 grams of sugar, then there are 35x g of sugar in x bottles of soda.
Each bottle of juice has 10 grams of sugar, then there are 10y g of sugar in y bottles of juice.
In total, there are 35x+10y g of sugar.
All bottles collectively contain 385 grams of sugar, thus

3. Solve the system of two equations:

Substitute the first equation into the second equation:
