Answer:
Marcelle will use 4 plates of the 25 lb & 2 plates of the 5 lb to fabricate the 110 lb weight lifting bar.
Step-by-step explanation:
There are 6 plates which consist of 25 lb plates and 5 lb plates.
We need to figure out how many of each one compose 110 lb.
Thus, 25 x 4 = 100... 4 plates of 25 pounds.
5 x 2 = 10 ... 2 plates of 5 lbs.
100+10= 110, which is our goal! And a total of 6 plates were used!
All things put into great consideration, Marcelle will use 4 plates of the 25 lb & 2 plates of the 5 lb to fabricate the 110 lb weight lifting bar.
I hope this helped!

Step-by-step explanation:
2 days= 24 hours in 1 day, so multiply that by 2 to get 48 hours total.
Now find the amount of time the wild fire doubles by dividing 48 total hours by 6. So it will double 8 times
The size was 1 acre. Let's multiply by 2, 8 times
1
2
4
8
16
32
64
128
The fire will cover 128 acres in two days.
