To the nearest tenth which choice is length of ac

there is no photo

Step-by-step explanation:

but to answer the question for example: 0.04 would round down to the nearest tenth 0.0 and 0.05 would round up to 0.1      . So if the number is 5 or above round up or if it is 4 or below round down, hope this helps

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
