Step-by-step explanation:
I got it on Khan.
0 is 500mg and the numbers above are larger.
The area of the rectangular garden is 50 x 10 = 500 square feet.
The perimeter of the rectangular garden is 50 + 50 + 10 +10 =120 feet.
The perimeter of the square also needs to be 120 because it is using the same amount of fence.
Divide 120 by 4 sides: 120/4 = 30
Each side of the square garden would need to be 30 feet.
The area of a square is Side^2, 30^2 = 900 square feet.
The square is 900 - 500 = 400 square feet more.
Y= -x-1
y= -5x-17 Multiply the 1st equation by (-1) & then add up the result to the 2nd one:
-y = -1(-x) -1(-1)
y = -5x-17
-----------------
0y = -4x-16 ===> x=-4 & y=3
Answer:
There were 15 students in van and 51 students in the bus.
Step-by-step explanation:
Let the number of students in each van be 'x'.
Let the number of students in each bus be 'y'.
Given:
For High School A
number of vans = 11
Number of buses =9
Number of students = 624
now we can say that;
Total Number of students is equal to sum of the number of vans multiplied by the number of students in each van and Number of buses multiplied by the number of students in each bus.
framing in equation form we get;
For High School B
number of vans = 5
Number of buses = 1
Number of students = 126
now we can say that;
Total Number of students is equal to sum of the number of vans multiplied by the number of students in each van and Number of buses multiplied by the number of students in each bus.
framing in equation form we get;
On solving both equation we will get the number of students in vans and buses.
First we will multiply equation 2 by 9 we get;
Now Subtracting equation 2 from equation 1 we get;
Now dividing both side by 34 we get;
Now we will substitute the value of 'x' in equation 2 we get;
Hence There were 15 students in van and 51 students in the bus.
