Let x be larger integer so x-3 is the smaller
so x^2+ x-3 = 87
x^2 +x -90=0 and factor
(x-9)(x+10)=0
x=9 or x=-10 but x must be positive
so x=9 and smaller number is 6
D is the correct answer
x+5=10: subtract 5 from both sides the 5 will cancel out leaving x=5
x+5=10
-5 -5
x=5
A, because in order to find the price for each unit you must divide the total price by the number of units bought and 9p=54.90 you would end up dividing both sides by nine which would then get you to find the price of each unit
The answer would be .5 pounds
1 ounce is equal to .0625 lbs
so 8 * .0625 = .5
hope this helps :)
