Answer:
1. -9 because -9x6= -54, -10 because 5 x -10= -50, and x=1 because -2 x 1= -2
Step-by-step explanation:
Answer:
No Solution
Step-by-step explanation:
| −2n | + 10 = −50
Subtract 10 on both sides
|-2n|+10-10=-50-10
Simplify
|-2n=|=-60

Answer:
200
Step-by-step explanation:
First, we know that 1 meter=100 centimeters, so we need to find a common measurement. Lets right it all as meters, so we dont get confused. Then we can find the total area of the floor by multiplying the too side lengths together:
400 centimeters x 200 centimeters= 80000 centimeters!
The total area of the floor is 80,000 centimeters
Now find the area of each tile:
20 centimeters x 20 centimeters= 400 centimeters
Now to find how many of those tiles can fit in that floor, we divide 80,000 by 400.
80,000/400=200
He needs 200 tiles.
Hope this helps!

Answer:
x=6*sqrt(5)
Step-by-step explanation:
We use Pythagoras' theorem:
x^2 =6^2+(24/2)^2
x^2 =6^2+12^2
x^2 =36+144
x^2=180
x=sqrt(180)
x=sqrt(9*4*5)
x=3*2*sqrt(5)
x=6*sqrt(5)
