Answer:
there were 200 children and 500 adults at the show
Step-by-step explanation:
7x+10y=6400
x+y=700
x=700-y
7(700-y)+10y=6400
4900-7y+10y=6400
-7y+10y=1500
3y=1500
y=500
x=700-y
x=700-500
x=200
So you know that Booker has 85 video games and that he has 3 shelves to put each of them on. And you also know that each shelf can hold 40 games.
So if you multiply 40 games by 3 shelves to find the total number of games that he can put on all the shelves, you will get 120 games.
You know that Booker has 85 video games, and you can fit 120 video games on all the shelves.
To find how many more games Booker can fit in the shelves, you subtract 120 by 85, and you will get 35 video games.
So, Booker can fit 35 more video games in the shelves.
I hope this helps :)
Given problem: 
.
Solution: We can see that first we have 8 and 2 numbers in front of 10's powers.
So, we need to simplify 8 over 2 first.
If we divide 8 by 2, we get 4.
Now, let us work on 10's and their powers.
is being divided by 
We can apply quotient rule of exponents remaining part.
According to quotient rule of exponents, 
If we apply same rule, we need to subtract exponents of 10's.
If we simplify exponent part -4-(-2), it will give us -4+2 =-2.
So, 
And final answer would be 
.
Hello from MrBillDoesMath!
Answer:
76.5 ( the last choice)
Discussion:
Sum =
1/2 ( 1! + 2! + 3! +4! +5!) =
1/2( 1 + 2+ +6 + 24 + 120) =
1/2(153) =
76.5
which is the last choice
Thank you,

Answer:
19 feet
Step-by-step explanation:
The perimeter is calculated by multiplying the sum of length and width by 2
width is 3 less than length so if we call the width x the length would be x + 3
2×(x + x + 3) = 4x + 6 and
4x + 6 = 70 subtract 6 from both sides
4x = 64 divide both sides by 4
x = 16
The length is x + 3 so the answer is 19 feet
