13 1/2 containers of sugar.
For this case we have the following equation:

The variables are:
t: time in hours
d (t): distance traveled in miles.
We evaluate the distance traveled after 4 hours.
So we have that for t = 4:
Answer:
d (4) = 68
This means that after 4 hours Joanna cycled for 68 miles total
The like terms would be the numbers that are the same.
9 and 3
Negative z and negative 2z
Hope I helped :)
$7.50 x 46 hours = $345.00
His gross pay is $ 345.00 per week
I am assuming from What I have found is that a is the base , b is angle between a and x and x is the hypotenuse .
So we know that
cos θ =base/hypotenuse
here θ = 3π/8 =67.5 degree
cos 67.5 =0.38268
so
0.38268=a/x
x=25/0.38268
x=65.32873
