Okay so if 5 notebooks equals $4.65 and you want to find the cost of two I suggest finding the cost of one and then multiplying it by two.
so 5 notebooks = $4.65 1 notebook = $?
How do you get from 5 to 1? you divide by 5. now whatever you do to one part of a fraction, you need to do the same to the other. You need to divide the $4.65 by 5.
$4.65/5=$0.93
So 1 notebook is $0.93 2 notebooks equals twice that ($0.93 × 2) which is $1.86
You can cross-multiply to find the answer. stands for the unknown price of 2 notebooks. 5 notebooks/$4.65 = 2 notebooks/ you multiply 5 and x & 2 and 4.65, so: 5x = (2)(4.65) 5x = 9.30 then, you divide 5 on both sides, to get the x alone, so: x = 9.30/5 so the answer is $1.86 for 2 notebooks.
Step-by-step explanation: so the farmer walks the length then the width of the field then the diagonal which we don't know using pythagorean to find that last side then add the values 51^2+68^2=c^2 and 51+68+85= 204
