Hello! So the equation you have to solve is 49 + j = 81. You want to figure out j, so you have to isolate the variable. This means, you should subtract 49. In math, if you do something to one side of the equation, you have to do it to the other. So, you must subtract 49 from 81. This means j= 32.
I hope this helps! If you need help with how to do the subtraction equation 81-49, please let me know!
Use the distributive property:
And
Problem 2
The figure has one line of symmetry.
This line is vertical and passes through the direct center. Imagine folding one side to have it land perfectly on the other side.
================================
Problem 3
The letter Z has rotational symmetry.
If we were to look at the letter, close our eyes, and then rotate it 180 degrees (or have a friend do so), we wouldn't see any difference if we opened our eyes again. The "before" and "after" images being identical is what gives it rotational symmetry. Put another way, rotating the letter 180 degrees has it line up with itself.
The answer is 271.04 because you have to do 242 times .12 then add your answer to 242.
