Answer:
a=1, b=7. (1, 7).
Step-by-step explanation:
3a+6b=45
2a-2b=-12
-----------------
simplify 3a+6b=45 into a+2b=15
and 2a-2b=-12 into a-b=-6
--------------------
a+2b=15
a-b=-6
--------------
a+2b=15
-(a-b)=-(-6)
-----------------
a+2b=15
-a+b=6
---------------
3b=21
b=21/3
b=7
a+2(7)=15
a+14=15
a=15-14
a=1
12/100
x/8400
cross multiply to get 100x = 100800
x = $1008 commission
Answer:
Try to find the unit rate for bulk items that you have for these and then compare all of the prices together.
Orio has 9 more than Ted. Using the equation y=mx+b to find Orios number of comic books, we can plug 2 months to substitute for the variable x.
2(2)+15 becomes 4+15, which is 19.
We know Ted has 10 comics after 2 months from the graph.
19-10= 9. :)
