Answer: a. (0, -300), (1, -180), (2, -60), (7, 540)
b. T=120D-300
c. $28080
Step-by-step explanation:
a. T=120D-300 ==> per week
D=0: T=120(0)-300
D=0: T=-300 ==> (0, -300)
D=1: T=120(1)-300
D=1: T=120-300
D=1: T=-180 ==> (1, -180)
D=2: T=120(2)-300
D=2: T=240-300
D=2: T=-60 ==> (2, -60)
D=7: T=120(7)-300
D=7: T=840-300
D=7: T=540 ==> (7, 540)
b. T=120D-300
c. T=120(7)-300
T=840-300
T=$540 per week
1 year = 52 weeks
540*52=$28080
So 5k-7=-7
You need to do the opposite of addition,which is subtraction so...
5k-7=-7
+7
__
K=0
and to double check it,replace the (or variable) with our answer (0)...
so
5×0-7=-7
solve the problem...and
-7=-7√
20:12
i think. 20 being the number of total students to 12 which is the number of boys
