Makenzie is going scuba diving. For the first dive, she dives 36 feet.
During her second dive she goes down an additional 55 feet farther than
her first dive. How deep was her second dive?

Mackenzie's second dive was -91 feet.

Step-by-step explanation:

This is because if we look, we can see Mackenzie dived down -36 feet. She then dived -55 feet. To get our answer, we can just ignore the negative sign and do the addition normally. So, 36 + 55. After you finish the addition, don't forget to add the negative sign!

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
