Step-by-step explanation:
X+y+z=t
simple..
there are no other numbers that we have to follow like (1/2x or 3/4y) so it is just all together=t. the x, y, z will equal t because t is the total number of students taking three languages. And that number should be equivalent to x,y,z combined.

Answer:
196
Step-by-step explanation:
100 divided by 12 is 8 r 4 24 x 8 = 192, 192 + 4 is 196
Georgia worked overtime on 4 of the 5 days. Her total overtime hours were
... (12-8) +(9 -8) +(10 -8) +(10 -8) = 4 +1 +2 +2 = 9
Then her pay for the week is
... (hours) × (pay per hour)
... = ((7 + 4×8) +1.5×9) × $7.50
... = 52.5 × $7.50
... = $393.75 . . . . Georgia's gross pay for the week
_____
Pay for "time and a half" can be computed by multiplying pay by 1.5 for overtime hours, or multiplying overtime hours by 1.5 and using straight pay. Either way, it is (overtime hours)×(1.5)×(straight pay).
