Answer:
what i would do is just divide each of the fractions until you get 0.6.
for example if you divide 2/3 you get 0.6
which is your answer, or B
Step-by-step explanation:
we know
distance =time *speed
from given question we have following equation
4*t+(1.5-t)*8=10
4*t+12-8t=10
12-4t=10
-4t=10-12
4*t=2
t=0.5 hour
hence at speed 4 miles per hour he crosses 4*0.5=2 miles
at speed 8 miles per hour he crosses 8*(1.5-0.5)=8 miles
I think for A it is either 54-p=? or 54 divided by p
Answer:

Step-by-step explanation:
Given line = 30x - 5y = 5 or y = 6x + 1
so, the slope of the given line is 6.
now, let the line which is perpendicular to the given line be y = mx + c
where,
m = slope of the line
c = constant
As we know, if two lines are perpendicular to each other, the value of product of there slopes are -1.
so, slope of given line × slope of perpendicular line = -1
⇒ 6(m) = -1
⇒ m = 
By substitutiong the value of m in the equation, we get;
⇒ 
For c,
as the point (0,-3) passes through the line, we get;
⇒ 
⇒ 
Hence,
The line which is perpendicular to the given line and passes through (0,-3) is
.
If 18000 divided by n equals 300 then n equals 60.
