If the line is perpendicular, that means the slope has to be opposite, so it will have a slope of -1/2
Fill in the point that it has to pass through on y and x
1=-1/2(0) + b
1=0+b
1=b
Then go back to the standard form y=mx + b and fill in the slope and y intercept
Y= -1/2x + 1
The least common denominator of 3/8 and 1/4 is the same as the least common multiple of 4 and 8.
List the multiples.
4: 4, 8, 12, 16, ...
8: 8, 16, ...
The least common multiple of 4 and 8 is 8.
The least common denominator of 3/8 and 1/4 is 8.
25 students were surveyed in total.
make all the fraction have the same denominator and you will get 3/5=24/40
1/4=10/40 and 1/8=5/40.
24/40 is equal to 60%
therefore 15 kids like the color green which is the same thing to 60% of the kids asked like green. 15 is 60% of 25, therefore 25 kids were serveyed
