At a pumpkin patch, if armando guesses the weight of his pumpkin within 0.3 pounds, he gets to take the pumpkin home for free. if his pumpkin weighs 4.9 pounds, which two equations can be used to find the minimum and maximum weights he can guess in order to get his pumpkin for free? a. x – 0.3 = 4.9 and x – 0.3 = –4.9 b. x + 0.3 = 4.9 and x + 0.3 = –4.9 c. x + 4.9 = 0.3 and x + 4.9 = –0.3 d. x – 4.9 = 0.3 and x – 4.9 = –0.3

Let x be the weight of the pumpkin, that Armando suppose to be and the real weight is 4.9 pounds. The difference between these weights is x-4.9 pounds. If Armando guesses the weight of his pumpkin within 0.3 pounds, then

.

The minimum weight he can guess is x-4.9=-0.3 and the maximum weight he can guess is x-4.9=0.3 (the minimum and the maximum should be at the endpoints of the interval ).

correct choice is D.

you would need to know all the numbers that are on there

step-by-step explanation:

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
