Answer:
A. $6.67
Step-by-step explanation:
a) 2y -3x + 8
a) y = - 3/2x + 8/2
a) y = - 3/2x + 4
b) 5y - 15x = -30
b) 5y = 15x - 30
b) y = 15/5x - 30/5
b) y = 3x - 6
3x - 6 = 3/2x + 4
3x -3/2x = 4+6
3/2x = 10
x = (10) / (3/2) = $6.67

Answer:
7 hours/week
Step-by-step explanation:
A "unit rate" is found by dividing one quantity by the other so that the denominator of the result is 1 (a unit). Often, we want the units of the independent variable in the denominator. Sometimes, we don't know what that is, because it depends on the intended use of the rate.
(14 h)/(2 wk) = 7 h/wk
__
When numerator and denominator have the same units, the result is a pure number (one with no units). If that number is a fraction, sometimes it is expressed as a percentage; other times, it is left as a fraction or written as a ratio with a colon, such as 1 : 35.
Here, both units are time, so the "unit rate" could be expressed as a fraction. We know there are 168 hours in a week, so this rate could be ...
(14 hours)/(2·168 hours) = 1/24 . . . . . with no units
