Mrs. Rodger got a weekly pay-raise of $145. If she gets paid every other week, write an integer describing how the raise will affect her paycheck.
Let the 1st paycheck be x (integer). Mrs. Rodger got a weekly pay-raise of $ 145. So after completing the 1st week, she will get $ (x+145). Similarly after completing the 2nd week she will get $ (x + 145) + $ 145. = $ (x + 145 + 145) = $ (x + 290) So in this way, at the end of every week, her salary will increase by $ 145.

DNA is known for its familiar twisted shape. This shape is often described as a spiral staircase or twisted ladder. DNA is a nucleic acid with three main components: nitrogenous bases, deoxyribose sugars, and phosphate molecules. Interactions between water and the molecules that compose DNA cause this nucleic acid to take on a twisted shape
