Maria is weighing a glass jar filled with marbles. the weight of each marble is 4 grams and the weight of the empty jar is x grams. there are 72 marbles in the glass jar and the total weight of the marbles and the glass jar is 703 grams. which equation could be used to find x, the weight of the empty glass jar? a. 703 = 4x ÷ 72 b. 703 = 4(72) + x c. 703 = 4x + 72 d. 703 = 72x + 4

B.  

703 = 4(72) + x

Step-by-step explanation:

total weight of marbles and jar = weight of marbles + weight of jar

weight of marbles = number of marbles * weight of each marble

                                = 72 *4

total weight of marbles and jar = 703

weight of jar=x

total weight of marbles and jar = weight of marbles + weight of jar

703 = 72*4 + x

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
