Carl knows that the area of a given circle is 400 cm2. he wants to defend an informal argument that the area of a circle can be approximated by dividing the circle into congruent segments, rearranging the segments to resemble a parallelogram, and replacing the dimensions of the parallelogram with appropriate values from the circle. carl divides the circle into 6 congruent segments and makes his calculations, but the area he calculates for the circle is only 350 cm2. how could carl defend his informal argument?

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
