Answer:
D No, the integer with the larger absolute value always determines the sign of the sum.
Step-by-step explanation:
Suppose the integer you start with is +3. Adding -1 or -2 or -3 to that will result in 2, 1, or 0, none of which are negative. Only when you add a negative number with an absolute value greater than 3 will you get a sum that is negative. That is, <em>the number in the sum that has the largest absolute value determines the sign of the result</em>. (This is most important when the signs differ, but it is also true when the signs are the same.)
Jack has 212 marbles.
Step-by-step explanation:
Jack and Watson have = 365 marbles
Jack and Asher have = 263 marbles
Let,
x be the marbles Jack have
y be the marbles Watson have
z be the marbles Asher have
According to given statement;
x+y=365 Eqn 1
x+z=263 Eqn 2
Watson has three times as many marbles is Asher.
y=3z Eqn 3
Putting y=3z in Eqn 1;
x+3z=365 Eqn 4
Subtracting Eqn 2 from Eqn 4
Dividing both sides by 2
Putting z=51 in Eqn 2
Jack has 212 marbles.
