Answer:
4
Step-by-step explanation:
25+25=50
50*2=100
100/25=4
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.
It’s d because one week would b 210 making it 790 and 3 more days would make it 700. 7+3 = 10 days
300 seconds.
First make a proportion:
45/3=x/20
In order to do this now you do:
(45×20)÷3
45×20=900
900÷3=
300
