There are 11 trains containing giraffes and 7 trains containing rabbits.
<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the number of train with giraffes and y represent the number of train with rabbits.
Hence:
25x = 40y
25x - 40y = 0 (1)
Also:
25x + 40y > 500 (2)
From both equations:
A possible solution is x = 11, y = 7
There are 11 trains containing giraffes and 7 trains containing rabbits.

Answer:
72.4 seconds
Step-by-step explanation:
We are given that,
Time taken by each person in the team = 18.1 seconds
Number of members in the team = 4
It is required to find the total time taken by the team to finish the race.
Thus, the time taken taken = 4 × 18.1 = 72.4 seconds
Hence. the team finished the race in 72.4 seconds.
Answer: 
Step-by-step explanation:
Given
The two communication mask are 2 km apart
Ubi's home is 500 m east of one of the mask
Suppose its distance from the other's is x
From the figure, we can write
x = 8, y = 0
y=
x-4
y=-
x+2
We substitute y=x-4 into the y for y=-x+2, and we get:
x-4 = -x+2
+x +x
x -4 = 2
+4 +4
x = 6
(4)x = 6 (4)
The 4's cross out and we get:
3x = 24
/3 /3
x=8
Not we substitute x(8) into one of our original equations: y=x-4
y=x-4
y=(8)-4
y=4-4
y-0
We get our final answer: (8,0)
Hope that helps!
