Answer: she worked 8 hours at Job A
She worked 16 hours at Job B
Step-by-step explanation:
Let x represent the number of hours that she worked job A.
Let y represent the number of hours that she worked job B.
Kathy works two part-time jobs for a total of 24 hours a week. This means that
x + y = 24
Job A pays $6.00 per hour, and Job B pays $7.30 per hour and she made $164.80 for the week. it means that
6x + 7.3y = 164.80 - - - - - - -1
Substituting x = 24 - y into equation 1, it becomes
6(24 - y) + 7.3y = 164.80
144 - 6y + 7.3y = 164.80
- 6y + 7.3y = 164.80 - 144
1.3y = 20.8
y = 20.8/1.3 = 16
x = 24 - y = 24 -16
x = 8

Answer:
12 cm
Step-by-step explanation:
The rule regarding secants and/or tangents is that the product of distances from their common point to the two intersection points with the circle is the same.
For the tangent the "two" intersection points with the circle are the same point, so ...
product of tangent lengths = product of secant lengths
(8 cm)(8 cm) = (4 cm)(4 cm +x)
Dividing by 4 cm gives ...
16 cm = 4 cm + x
12 cm = x
