Answer:
7:20 pm
Step-by-step explanation:
25 + 55 = 80
80 - 60 = 20
Add 2 hours to 5
Answer:
5 sets
Step-by-step explanation:
The average number of pieces per set is the ratio of the total number of pieces to the total number of sets.
Let x represent the number of 3-piece sets. Then the total number of pieces is ...
3x +5(5) +10(2) = 3x +45
The total number of sets is ...
x +5 +2 = x +7
We want the ratio of these numbers to be 5 pieces per set:
(3x +45)/(x +7) = 5
3x +45 = 5x +35 . . . . . multiply by (x+7)
10 = 2x . . . . . . . . . . subtract (3x+35)
5 = x . . . . . . . . . divide by 2
Divya owns 5 sets with 3 pieces.
_____
<em>Alternate solution</em>
Each 10-piece set has 5 more pieces than average, so the two of them total 10 more pieces than average.
Each 3-piece set has 2 fewer pieces than average. The total number of 3-piece sets must have a total of 10 fewer pieces than average in order to balance the excess of the 10-piece sets. That is, there must be 10/2 = 5 of the 3-piece sets to have a total lof 10 fewer pieces than average.
Altogether, the differences from average must total zero.

I would say c. you welcome for my so called help
We have been given a Quadratic equation, where we have to find the real values of x ~
So, let's proceed with middle term splitting method :
Now, we have two conditions here~
Either (x + 6) = 0
or (x - 1) = 0
Answer:
5 hours.
Step-by-step explanation:
- If the train travels at a speed of 80 kilometers per hour, and a kilometer is equivalent to 1000 meters, then the train travels at a speed of
- Then, to reach the 400,000 meters, it will take
