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

step-by-step explanation:

when you realize that you dont know just realize i just took a test and im so smart

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
