Answer:
2x-6
Step-by-step explanation:
Let mass of truck be t
mass of car A be a
and carB be b
so , a=2b-5
t=a+2135
putting a into t...
t=2b-5+2135
so, a+b+t=11350 ( putting all values)
2b-5+b+2b-5+2135=11350
so b=1845
a=3685
t=5820
so weight of Car A is 3685 lb
weight of Car B is 1845 lb
and truck is 5820 lb ......answers !!
Answer:
The answer is 852,00.
Step-by-step explanation:
If you multiply 7,100 x 12.
1/4 x 4/7
do the top numbers first. 1 x 4 is 4do bottom numbers next 4 x 7 is 28
that leaves you with 4/28. But you have to reduce.
4/28 = 2/14 = 1/7 (notice I just cut both the top and bottom numbers in half each time I reduced until I couldn't reduce any more).
So, final answer is 1/7
