Answer:
x=2
Step-by-step explanation:
Quotient means division
20/(x+3) =4
Multiply each side by (x+3)
(x+3)*20/(x+3) =4(x+3)
20 = 4(x+3)
Divide each side by 4
20/4 = 4(x+3)/4
5 = x+3
Subtract 3 from each side
5-3 = x+3-3
2 =x
Answer:
there is a 0.02 or 2% difference
It’s -63 all you would be multiple like normal 63 which then you put a negative symbol on front
Average speed of cyclist = x
average speed of car = 3x
x = 225/5
x = 45km/h
3x = 3(45)
3x = 135km/h
average speed of cyclist = 45km/h
average speed of car = 135km/h
Samantha and Mia are 13 km apart from each other.
<h3>What is
Pythagorean ?</h3>
A right triangle's squared sides add up to the hypotenuse's squared length, according to the Pythagorean Theorem.
Mia is 7 kilometers north of Julia's home as she walked at a speed of 7 kilometers per hour.
Samantha walked at an average speed of 11 km/h, and she is now 11 kilometers west of Julia's home.
A right-angled triangle is formed by Julia's house, Mia and Samantha's locations after one hour, and the figure's points.
Hypotenuse of the triangle, which measures distance between the females
the Pythagorean theorem,
H² = P² + B²
H² = 7² + 11²
H² = 49 + 121
H = √170
H = 13.038
H = 13km
Between them, there is a 13 kilometer distance.
