Answer:
Step-by-step explanation:
12a=x
4a+6b=10
2a+3b=5
2a-4b=12
a-2b=6
2a+3b+1=a-2b
a+5b+1=0
a=-1-5b
2(-1-5b)+3b=5
-2-10b+3b=5
-2-7b=5
-7b=7
7b=-7
b=-1
-1-5*-1=a
-1+5=a
4=a
4*12=48
12a=48
Hope this helps :)
D = 900t
because if you want to simplify t (2 hours) into one then you divide 1800 by 2 and that gives you the constant of proportionality (slope) of 900. Using this information you can write the expression d = 900t.
