Answer:
(-2,4)
Step-by-step explanation:
This implies 
.
This means 
and 
.
Subtract 3 on both sides for first equation: 
.
Add 3 on both sides for the second equation: 
.
So the pre-image (x,y) is (-2,4) if the image is (1,1).
Let's check:
So the solution has been checked and verified.
Answer:
5/6
Step-by-step explanation:
Since 1/3÷2/5 can also be written as 1/3/2/5
So the ÷ can then be converted to × and 2/5 will change to 5/2
So let's solve
1/3×5/2
5/6
Since there is no common number that can divide the two
So the final answer is 5/6
Answer:
45 degrees
Step-by-step explanation:
the right angle is 90 degrees and one angle is 45 degrees and 90+45=135 and 180-135=45 so 45 degrees is the missing angle
OK so each block is 3cm tall and 3.5cm wide (because 2 are 7cm wide)
so to measure the perimeter count all the side values for example:
the 5 squares at the bottom which measure 3.5cm each adds up to a total of 17.5cm then if you add the top 2 flat sides that's another 2, 3.5cm which adds up to 7cm. 17.5cm + 7cm = 24.5cm then their are 3 walls on each side measuring 3cm each so 3cm * 6 = 18
24.5cm + 18cm = 42.5cm (I think this is correct)
