Every 20th person who passes the student centre.
The people passing the student centre are very likely to be students and you're very likely to get a mix of lots of different students producing reliable results.
Well if you have four rows, then you could put them in four groups of twelve. 12 times 4 is 48, meaning you would have two left over.
Answer:
y-3x=2......1
y=-2x-8 ......2
substituting value of y in equation 1
-2x-8-3x=2
-5x=2+8
x=10/-5=-2
substituting value of x in equation 1
y-3×(-2)=2
y+6=2
y=2-6=-4
x=-2
y=-4

Answer:
102
Step-by-step explanation:
You can split that shape up into 2 rectangles to make it easier get the area of each rectangle and add them together.
Step 1
Identify the width and height
Step 2
Multiply the sides to get the answer
For example if we split the shape we will have 9,10 and 2,6
9 times 10 is 90
and 2 times 6 is 12
Add the 2 and get 102
Hopefully this helped.
