Answer:
2nd row, circle is <u><em>6</em><em>x</em><em> </em><em>+</em><em> </em><em>2</em><em>y</em></u><em>.</em>
3rd row, rectangle is <u><em>3</em><em>x</em><em> </em><em>+</em><em> </em><em>y</em></u><em> </em>and circle is <u><em>5</em><em>x</em></u><em>.</em>
Step-by-step explanation:
As the question say when 2 rectangles, at the sides are add up together, it will form circle in the middle. So in order to find circle or rectangle, you either have to add or substract :
For 2nd row, circle,
T/L(r) + B/R(r) = M(c)
4x + 3y + 2x - y = M(c)
6x + 2y = M(c)
M(c) = 6x + 2y
For 3rd row, rectangle,
T/L(r) + B/R(r) = M(c)
x + 4y + B(r) = 4x + 5y
B(r) = 4x + 5y - x - 4y
= 3x + y
For 3rd row, circle,
T/L(r) + B/R(r) = M(c)
2x - y + 3x + y = M(c)
5x = M(c)
M(c) = 5x
* Take note, for 3rd row, you first have to find the rectangle then circle.
Symbols :
- T/L(r) = Top/Left (rectangle)
- B/R(r) = Bottom/Right (rectangle)
- M(c) = Middle (circle)
Find a number that you can make 10,100,or any 1 followed by zeroes
then,multiply both numerator and deno with that number
Then write down just the top number, putting the decimal point in the correct spot (one space
from the right hand side for every zero in the bottom number)
One of the 2s are 200 the other is 20,5s 50,000 and then 5,00
