Answer:
a) x = 5
b) x = 4
Step-by-step explanation:
a) 
= 9.5
3x+4 = 9.5(2)
3x = 19-4
x = 15/3
x = 5
b) 
= 5
7+2x = 5(3)
2x = 15-7
x = 8/2
x=4

In 6 hours, Mr. White takes a total of 30 min in breaks.
36 h
=
6 h
×
6
In 36 hours
, there are 6 sets of 6 h
.
Hence we can multiply the number of minutes in breaks taken in
6 h
ours by 6 to obtain the number of minutes in breaks taken in 36 h
ours.

F(x) = -2.5x + 135...where x is the number of weeks, and f(x) = total weight
Answer:

Step-by-step explanation:
Answer:
The center is (-4,-6) and the radius is 8
Step-by-step explanation:
(x+4)²+(y+6)²=64
The equation of a circle can be written in the form
(x-h)²+(y-k)²=r^2
Where (h,k) is the center and r is the radius
Rewriting the equation
(x - -4)²+(y- -6)²=8^2
The center is (-4,-6) and the radius is 8
