Answer:
a) 10*10 inch, b)yes, c) 15
Step-by-step explanation:
a)
we need to calculate the Greatest Common Factor between 30 and 50

then, the square tiles will be 10 inch *10 inch
b) it will change because they don't need to have the largest slab possible so they will use any other comon factor with a size they consider correct for the cheese.
c)

15 squares of 10inch*10inch of cheese could be cut.

Answer:
The slope equals the rise divided by the run: . You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope.
Step-by-step explanation:
Guppies: u
Goldfish: o
3 times as many guppies as goldfish
3*o = u (there are more guppies than goldfish)
o + u = 20
o = 20 - u
Substitute in (20 - u) for o in the first equation and solve:
3* (20 - u) = u
60 - 3u = u
60 = 4u
u = 15
He has 15 guppies. Then substitute in the number of guppies into either equation to find the number of goldfish:
o + u = 20
o + (15) = 20
o = 5
Hope this helps! :)
