Look at this estimate of the cost of a bag of pears that weighs 6.78 pounds.

$1.41(6.78) - $1 * 7 = $7

which statements are true about the estimate? check all that apply.

the estimate is correct.

the estimate is incorrect.

the exact product is less than $7.

the exact product is greater than $7.

the answer is A and D

Step-by-step explanation:

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
