Answer:

5,440 squares.

Step-by-step explanation:

We have been given that a chessboard has 64 squares. At a chess tournament 84 chessboards were used.

To find the number of squares on 85 chessboards, we will multiply number of squares on each chess board by number of total chess boards.

\text{The number of squares on 85 chessboards}=\frac{\text{64 squares}}{\text{Chess board}}\times \text{85 chess boards}

\text{The number of squares on 85 chessboards}=\text{64 squares}\times 85

\text{The number of squares on 85 chessboards}=5440\text{ squares}

Therefore, there are 5440 squares on 85 chess boards.

How do I solve without s calculator?
baherus [9]
You could solve it ( without a graph) in 2 easy ways :

1 use the equation that you have written in pencil and solve for y

y=3=-x+4
y=-x +1

Or you could use the point slop form after you find the y intercept y=mx+b


-3=4(-1)+b
b= 1

So the answer would be y= -x +1


Hope this help of it does feel free to give the brainliest

​= <br> The solution set is <br> ​ 1/2(10x+16)-13=-3/5(15x-35)
-BARSIC- [3]

Answer: 13/7 or as a decimal 1.857142857

How did i get the answer:

Step 1: Simplify both sides of the equation.

so 1/2 of 10 is 5, 1/2 of 16 is 8

-3/5 of 15 is -9 and -3/5 of -35 is POSITIVE 21

all together should look like 5x+8+−13=−9x+21

(now we have to combine like terms)

8+ -13= -5

5x -5 = -9x+21

Step 2: Add 9x to both sides

5x + 9x= 14x

14x -5 = 21

Step 3: Add 5 to both sides.

21+5= 26

14x=26

Step 4: Divide both sides by 14.

26/14= 1.85714286 or 13/7
