Question

1. determine whether each statement is true or false. select the correct cell in each row. statement true false the sum of -6, 8, and -4 is equal to zero. the sum of 9, -5, and -4 is greater than zero. the sum of 5 and -\frac{12}{3} is less than zero. the sum of -\frac{18}{3} and 7 is greater than zero.

Explanation:

Step1: Calculate sum of -6, 8 and -4

$-6 + 8+( - 4)=-6 + 8-4=-2$
Since $-2
eq0$, the first statement is False.

Step2: Calculate sum of 9, -5 and -4

$9+( - 5)+( - 4)=9 - 5-4=0$
Since $0$ is not greater than $0$, the second statement is False.

Step3: Calculate sum of 5 and $-\frac{12}{3}$

$5+( -\frac{12}{3})=5 - 4 = 1$
Since $1>0$, the third statement is False.

Step4: Calculate sum of $-\frac{18}{3}$ and 7

$-\frac{18}{3}+7=-6 + 7=1$
Since $1>0$, the fourth statement is True.

Answer:

False, False, False, True
