Answer:
Below in bold.
Step-by-step explanation:
As we all know a car has 4 wheels and a motorcycle has 2 so we can write 2 equations:
x + y = 140 where x = number of cars and y = number of cycles.
4x + 2y = 370.............A
Multiply first equation by 2:-
2x + 2y = 280.............B
Subtract equation B from A:
2x = 90
x = 45.
So there are 45 cars and 140 - 45 = 95 motorcycles.
Answer:
The velocity is 17 m/s
Step-by-step explanation:
To find the velocity, we find the first differential of the displacement
That will be
S’(t) = 16t + 1/t
We simply proceed to replace t with 1
That will give;
16(1) + 1/1
= 16 + 1 = 17 m/s
You know each side is 9 meters long, meaning it’s a square. To find perimeter, add up all the sides aka. 9+9+9+9=36. To find the area, multiply one side by the other aka. 9x9 = 81.
Answer:
x = 40
Step-by-step explanation:
Simplifying
0.25x = 10
Solving
0.25x = 10
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '0.25'.
x = 40
Simplifying
x = 40
hope this helps
