To find their mph you would have to divide by 2 to find out how much they got in 1 hour instead of 2. You would have to do 4 2/3 / 2. An easier way to do this is just doing 14/3 x 1/2 which is the same thing except making 4 2/3 a fraction and changing divided by 2 to multiply 1/2. The answer you would get is 14/6, which is 2 1/3 miles per hour. To do this quickly you could just look at the question and divide 4 by 2 to get 2 and then divide 2/3 by 2 to get 1/3 and then add them up.
Hope this helps!
You would multiply $81.50x2.5 and you’d get 203.75
Answer:
Step-by-step explanation:
Step one:
for James
the initial mile covered= 6miles
the planned number of miles per day= 3miles
let the number of days be x
and the total distance in miles be y
the total distance for the x days day will be
y=6+3x------------1
step two:
for Aaron
the planned number of miles per day= 4miles
let the number of days be x
and the total distance in miles be y
the total distance for the x days day will be
y=4x------------2
The system of equations is
y=6+3x--2
y=4x----2
Step three:
for the number of days that Aaron needs to run to meet up with James, we need to equate the two equations to find x which is the solution
6+3x=4x
6=4x-3x
x=6days
This means that Aaron will have to run at 4mile per day consistently for 6 days to meet up with James
Reflection over the y-axis = change 
Compress by a factor of k = multiply by k
So, in your case, we first change the sign of the argument. Note that this has no effect, because f(x) is symmetric with respect to the y-axis:
Then, we compress the function, multiplying it by the scaling factor:
we are given three angles
first angle =x-4
second angle =3x
third angle =100
we can see that this is a triangle
and we know that
sum of all angles in any triangle is always 180
so,
first angle + second angle + third angle =180
now, we can plug values
and we get
now, we can solve for x
