4/5(2x 5)−4=1

drag and drop the statement that shows the solution to the equation into the box.

x=1 1/4

x=1 3/5

x=5/8

x=3 1/5

 5/8=0.625 4/5=.8

5/8 because 5/8=0.625 and because its 2x you multiply 0.625 by 2=1.25 then you do 1.25+5=6.25 4/5=.8    6.25 times .8=5 5-4=1   

X=5/8 or 0.625

If we convert the ounces to grams, there are approximately 283.495 grams of plant fertiliser

If nitrogen has 15% of this, all we have to do is divide this number by 100 to get the mass of 1% and multiply it by 15.

In the end, we end up with the mass of 42.5243 g
