Only number 5, check image above for question. . whichever answer best i’ll mark as “brainliest answer”.

I think it is 20%. I'm, not 100% percent sure.

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
