A factory made 886 jars of peanut butter. 443 of the jars contained creamy peanut butter. What percentage of the jars of peanut butter was creamy?

50%

Step-by-step explanation:

To find the percentage, we need to divide the amount of creamy peanut butter by the total amount of peanut butter. In this case, there are 443 jars with creamy peanut butter and 886 total jars.

What is 443/886? Well, you could divide it out, but you could also notice that 443 is exactly half of 886 and simplify to 1/2, which is equal to 0.5. Either way works, but one's just a lot quicker.

Next, we have to convert the decimal - 0.5 - into a percentage. To do this, we move the decimal point to the right two spots, getting us to 50, and then slap a percentage sign on there giving us a final answer of 50%.

Hopefully that's helpful! :)

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
