Answer:
x = 5/2
y = -1/2
Step-by-step explanation:
if both equations start with 'y=' then set the expressions equal to each other
3/5x - 1 = x - 3
add 1 to each side to get:
3/5x = x - 1
subtract 5/5x from each side:
3/5x - 5/5x = -1
-2/5x = -1
multiply each side by -5/2:
x = 5/2
y = 2 1/2 - 3
y = -1/2
There are 10 rooms per floor if there are 30 floors then there are 300 rooms
Answer:
Rounded, 22 yards.
Step-by-step explanation:
The pythagorean theorem states: a^2 + b^2 = c^2
a = 34, squared = 1156
b = 41, squared = 1681
Add those to get 2837.
√2837 = 53.26, rounded.
34 + 41 = 75
75 - 53 = 22
22 yards is your answer.
