Answer:
Step-by-step explanation:
since there is no given formula I'm guessing that's what we want to find?
use the dist. = rate * time formula for this kind of problem
or d = r*t ( this looks like the word "dirt" to me so I call this the dirt formula partly b/c it's dirt simple, and it's generally about moving across some give dist. of dirt :P )
so Jean's rate is 64 MPH
her total distance is 448 miles
rearrange the d = rt formula so that you are solving for the thing you don't know.. yet.... t (time) for this case
soooo...
d/r = t
plug in number
448 / 64 = t
7 = t (in hours)
Answer:
P = 12
Step-by-step explanation:
Given formula for the perimeter 'P' of a rectangle is,
P = 2L + 2W
If the values of L and W are,
L = 4 and W = 2
Perimeter of the rectangle = 2(L + W)
= 2(4 + 2)
= 2 × 6
= 12 units
Therefore, value of remaining variable 'Perimeter' = 12 units
(There is no use of 'pi' in calculating the perimeter of a rectangle).
Answer:
Normally, sequences don't go behind 1, but let's see for this one.
f(-1) = 1
Step-by-step explanation:
Let's sub for -1 in x.
f(-1) = 2(-1) + 3.
f(-1) = -2 + 3
f(-1) = 1

To do this you need to know simultaneous equations (which i don’t know if you have learnt it) but this is really hard to explain by words so i hope you can understand by the working out i did
