With a number of 328×41 and coming up with a answer of nearly 5,000 is not reasonable because just estimating it 300×10 is 3,000 so times that by 4 is 12,000.

Its not reasonable, here is why.

Grab a sheet of paper and follow along, write 328 x 41 and put 328 on top of 41.
multiply 8 x 1
multiply 2 x 1
multiply 3 x 1
multiply 8 x 4 which is 32
multiply 2 x 4 which is 8
multiply 3 x 4 which is 12
bring down the carry digit of 1
add 328 + 13120 which is 13448
or multiply 328 x 41 and u get 13448

The answer is not reasonable because its not the correct solution.

Let x be the length of each row.
Denver can plant 3 rows of a certain length with 2 seedlings leftover.
Total number of seeds he has = 3x+2 Denver can plant 4 rows of the same length with 3 seedling spots left empty.
Total number of seeds he has = 4x-3 Using (i) and (ii), we get= 3x+2=4x-3

Isolate variable terms: 2+3=4x-3
Answer= 5=X

To convert temperatures in degrees Celsius to Fahrenheit multiply by 1.8 and add 32 so the paper has a typo you would multiply 25 x 1.8 = 45 + 32 = 77F so 25 C is 77 F but the way it says it we would all be dead because 25 x 8 = 200 + 32 = 232 F it would be to hot for life. So the correct answer is 77°F Hope this helps! ;D
