10 cm. Because for each cm is 10 mm.
This is the concept of algebra, we are required to find a number,x, such that 87 decreased by three times a number is great than one hundred and sixty-five.
Supposed the number is x, three times the number will be:
3*x=3x
thus;
87-3x≥165
-3x≥165-87
-3x≥78
dividing both sides by -3 we get:
(-3x)/(-3x)≥78/(-3)
x≤-26
This implies that the number is less than or equal to 26
The rate of change is ur slope.
The table : company p
y/x = 0.4/10 = 0.04
the graph : company s
y/x = 6/100 = 0.06
Company s (the graph) has the greatest rate of change
d=rt
divide by r on both sides
d/r = t
300/60 =t
5=t
t=5 hours
d=rt
d/t =r
250/4.5 =r
55.5555555=r
55 5/9 miles per hour
Note the equal sign. What you do to one side, you do to the other.
Isolate the variable. Divide 4 from both sides
(-52)/4 = (4m)/4
m = -52/4
m = -13
-13 is your answer for m
hope this helps
