please help me. i’ve posted this question 4 times in an hour with no response. i needed it 20 mins ago.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
