Kara finds the value of  x. her work is shown below. step 1      14/72 = 12/xstep 2      14x = (72) (12)step 3        14x = 864step 4        x = 61.7 mileswhat is kara’s first error? kara should have written the proportion in step 1 as  12/72 = 14/x. kara should have written the cross-product in step 2 as  12x = (72) (12).kara did not correctly divide 864 by 14 going from step 3 to step 4.kara did not find the correct product of 72 and 12 going from step 2 to step 3.

we have been given work of kara to find the error if any.

there is no question or word problem which is used to make equation so step1 is correct without any question.

then she did cross product and got 14x=(72)(12)

which is also correct.

step 3 is multiplication of 72 and 12 which is also correct.

step 4 is for division of 14 into 864.

result of division is 61.7142857143 because 14 doesn't go evenly into 864.

rounded value of 61.7142857143 is 61.7 which is correct as shown in work.

so basically there is no error in her work.

but if you still say that there is error then we can say that she should have written answer as x=864/14 or 432/7 to get more accurate answer.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
