Answer:

25 girls

Step-by-step explanation:

Let

x denote number of boys

and

y denote number of girls

According to the statement that total 45 people came,

x+y = 45      => Eqn 1

And total paid amount was 175

So,

5x + 3y = 175    => Eqn 2

For solving, We will use the substitution method

So, from eqn 1

x = 45-y

Putting value of x in eqn 2

5(45-y) +3y = 175

225 - 5y + 3y = 175

-2y+225 = 175

-2y = 175-225

-2y = -50

2y = 50

y = 25

Putting y =25 in eqn 1

x+25 = 45

x = 45 - 25

x = 20

As y= 25

So, 25 girls came to the dance ..

Answer:

3w+10>2w+15

Step-by-step explanation:

If Jerry initially releases 10 videos a week and creates an additional 3 each week, he will create a total of 3w+10 videos, where w is the number of weeks. If Martin initially releases 15 videos a week and creates an additional 2 each week, he will create a total of 2w+10 videos, since w is maintained. Therefore, the inequality \fbox{$3w+10>2w+15$} can be used to find who creates more videos, where w is the number of weeks.
