In order to find the unit rate of acres per day, or in other words, how many acres can they plant in one day, you must divide 5/8, the number of acres planted, by 4/5, the number of days it took to plant. When you divide the two fractions, first set up an expression:
5/8<span>÷4/5
Then, to make things simpler, turn the division expression into a multiplication statement so that you have 5/8*5/4. Then multiply straight across and you get your answer as 25/32. This means that the workers can plant 25/32 acres per day.</span>
No. when plugging 4 into the equation, 0 is not the final result. instead it is 6.
square root of 2(4)+1 = square root of 9 = 3
3+3 = 6
and 6 is not 0 so x cannot = 4
I believe it’s a 76. It’s the only one that makes since
I don't feel like working it out/ maybe someone will give you the answer/ but basically you would set

and add it to

to equal 180( which is the degree of a line
so it looks like this:

and then solve( tell me if you need more clarification)
