X= 9 2/7 ( the first answer is correct )
Use the formula
Area= base times height.
You're given that area =300cm^2 and base=20 cm.
Plug these into the equation to get 300=20 x height. Now, you just need to solve for height. To do this, you need to undo the multiplication of b x h by dividing the area by the base.
So, h = 300/20
Simplify for an answer of 15.
So first you see that she picked 20 green peppers and that she picked 4 times more than red. So you take 4 x 5 and you should get your answer 20 so then the answer is 5.
X = 4/3 because set y=0.
so 0=3x-4. add 4 to both sides so
4=3x. divide both sides by. 3 and you get x=4/3.
