1 m = 100 cm
Multiply:
100 * 400 = 40000
So she ran 40,000 centimeters.
Answer: 18.7
Step-by-step explanation:
Find the lengths of AB, BC, and CA
AB = = 5 ≈ 7.1
BC = = 5 ≈ 7.1
CA = = 2 ≈ 4.5
7.1 + 7.1 + 4.5 = 18.7
Answer:
numbers are 3x,2x,5x
so 3x+2x+5x=10x=840
so x=84
so numbers are 252,168,420
X² + y = 4 and -y³ = 1x -5 are not linear equation because they contain a variable with a exponents. These types of equation are called quadratic equations.
The angles of a triangle add up to 180 degrees
180 - 80 = 100
Both of the unknown angles are the same. So...
100/2= 50
X = 50 degrees
