Answer:
Which expression is equivalent to 5(4x+3)-2x?a 18x+15b 18x+3c 7x+8d 2x+8
A-18x+15
Now, supplementary
angles sum up to 180°.
so hmmm say one has a measure of a°, and her sibling is 5 times larger, or 5 times that much, or 5a°, we know that both will sum up to 180°, thus

so, the smaller is that much, and her sibling is 5a, and you know how much that is, unless you mean
angels, and hmmmm both have wings and feathers and are wearing a gown, but doubt that's the case.
Answer:
two minute difference
Step-by-step explanation:
3/4 of an hour is 45 minutes. So they spent 3 hours and 45 minutes at the beach. They arrived at 10:30 so just add 3 hours and 45 minutes to their arrival time and you get 2:15pm. They left at 2:15pm
10:30+3:45=14:15
14:15=2:15
