On Monday Simon's class filled 3 2/5 boxes with books to donate to charity. On Wednesday the class filled 4 2/5 more boxes with
1 answer:
Simon class donated boxes of books
Given that,
On Monday Simon's class filled boxes with books to donate
On Wednesday the class filled more boxes with books
To find: total number of boxes of books donated
Total number of boxes of books donated = boxes filled in monday + boxes filled in wednesday
From given statement,
Boxes of books filled in monday =
Boxes of books filled in wednesday =
Therefore,
Total number of boxes of books donated =
Thus simon class donated boxes of books

Say that you're thinking of number
You multiply it by 8, and have
You add -1 (i.e., you subtract 1) and have
This equals -17, so you have
Add 1 to both sides
Divide both sides by 8:
So, you were thinking of -2.
A fisherman can row upstream at 4 mph and downstream at 6 mph. He started rowing upstream until he got tired and then rowed downstream to his starting point. The distance of how far the fisherman row if the entire trip took 2 hours is 9.6 miles

The speed of an object refers to the change of the object's distance within a specified time.
Mathematically, we can have;
Distance = speed × time
From the information given;
- The fisherman row upstream for 4 miles/ hour.
- The distance covered by the fisherman = 4 × t₁ ----- (1)
- The fisherman row downstream at 6 miles/ hour
- The distance covered by the fisherman = 6 × t₂ ------ (2)
- SInce it took the entire trip 2 hours, we can infer that:
- t₁ + t₂ = 2
- t₂ = 2 - t₁
From equation (2), replace the above value of t₂ into equation (2)
- d = 6 t₂
- d = 6(2 - t₁)
- d = 12 - 6t₁
From equation (1)
- d = 4 t₁
Equation both distance together, we have:
- 12 - 6t₁ = 4t₁
- 12 = 4t₁ + 6t₁
- 12 = 10t₁
- t₁ = 12/10
- t₁ = 1.2 hours
From t₂ = 2 - t₁
- t₂ = 2 - 1.2
- t₂ = 0.8 hours
From d = 4t₁
Replace t₁ with 1.2 hours
- d = 4(1.2 hours)
- d = 4.8 miles
Also, from d = 6t₂
- d = 6(0.8)
- d = 4.8 miles
Therefore, we can conclude that the distance of how far the fisherman row if the entire trip took 2 hours is (4.8+4.8) miles = 9.6 miles
