I'm having so much darn trouble! which decimals are equivalent to ? choose exactly two answers that are correct. a. 0.50 b. 5.0 c. 0.5 d. 0.05

The two decimals that are equivalent are option (A) and option (C). Hope this helps!

A and C are equivalent.
If you look in the tenths place, they both have a five while every other place is a zero. Although C doesn't have a zero in the hundredths place and ends there, it actually has an infinite amount of zeros.
0000.5000000000 is also equivalent to A and C, the zeros are just place holders.
A and C are equivalent, they are both 5 tenths which is the same as 0.50 and 0.5.

1.17+3.99a. you combine the terms with a to create 3.99 and the 1.17 stays because it has no like terms or a variable

The answer is 16.64 feetyour welcome
