In Step 2, Lara did not ensure that the second diamter was perpendicualr to the first diameter she drew.
The correct steps should be:
Step 1: Use the straightedge to draw a diameter of the circle. Label the points at which the diameter touches the circle as A and B.
Step 2: Draw a second diameter <em>perpendicular to the first diameter</em>. Label the points at which the second diameter touches the circle as C and D.
Step 3: Join the end points of the two diameters to form a square.
12,740 - 200= 12,540 Ft above sea level
C
By subtracting 18 to both sides you are separating the 3x because you are not ready to isolate the variable (x) in step 1
Hi! I'm happy to help!
To solve this, we have to divide the 18 pounds, in 1/8 portions. We do this with division. To make this problem easier to solve, we need to turn it into a multiplication problem (opposite of division). To still make the problem correct, we have to take the opposite of one of our numbers. Let's take 1/8, and turn it into 8, now we have the problem:
18×8=
Now all we have to do is multiply:
18×8=
144
He can make 144 croissants!
I hope this was helpful, keep learning! :D
