Yes they must close the pool 7 pm
Answer:
Step-by-step explanation:
Let the three numbers be x, y, z
So from the problem given we can get the equations as
:
x + y+z= 66
x=2y
z=1x/3
Now we will make equation 1 have only one variable using equation 2 and 3.
y=1x/2 since x=2y
Now using equations 1, 3 and 5 we will get
x+1x/2+1x/3=66
11x/6=66
x= 66*6/11
x= 36
y=x/2=36/2=18
z=x/3=36/3=12
Therefore:
x = 36
y=18
z=12
Answer:
y+2=-3(x-2)
Step-by-step explanation:
y+2=-3(x-2)
Answer:
The answer is B
Step-by-step explanation:
y=5x+2, as the slope is 5x, and the y-intercept is 2
