Answer:
32
Step-by-step explanation:
the denominators are the same, so just add the two fractions on the right and subtract it from the answer on the left.
3500/7+210/7=3710/7
subtract 3710 from 3742
= 32
Let
x--------> the border’s length
y--------> the border’s width
P--------> perimeter of the border
we know that
x=5+y------> equation 1
P=2*[x+y]-----> P=2x+2y
P <=180 ft
(2x+2y) <= 180-------> equation 2
substitute the equation 1 in equation 2
2*[5+y]+2y <= 180
10+2y+2y <= 180
4y <= 180-10
4y <=170
y <=42.5 ft
so
the maximum value of the width is 42.5 ft
for y=42.5 ft
x=42.5+5------> x=47.5 ft
the answer is
the width of the border is less than or equal to 42.5 ft
Answer:
I am confused what is the question?
4.9 then divide by .7 and you get 7 then 7x3=21
So, 21 Amoeba Proteus would be lined up to equal 3 Pelomyxa Palustris.
